== Purpose ==

GRASS GIS Community Meeting is a great occasion for folks to support the development by actively contributing to the source code, documentation (manuals, wiki, tutorials), translations, website or likewise. The '''community''' meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS GIS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and desiring to '''celebrate with us the 40th GRASS GIS birthday!!'''

In this meeting, we will work on GRASS GIS and integrations with related OSGeo projects. We will revise connection to QGIS to make it easier to maintain, and we will work on migration of the build to CMake to improve Windows builds including PDAL support. Furthermore, we will start moving documentation to Markdown to make it easier to contribute to and we will add images and examples for tools and workflows which still miss them. Finally, we will automate and document maintenance processes to reduce the burden on maintainers and thus improve the project sustainability.

Note that while we have our general plan, we can't accept any earmarked donations, i.e., we can't make any promises for a specific work to be done. We do require participants to work on GRASS GIS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project at that time given their skills and time available.

For the detailed agenda and individual's plans, see below.

== Sponsors ==

We welcome '''financial contributions''' to support the meeting and we are looking for sponsors to cover costs such as meals or to help reducing travel and accommodation expenses for GRASS developers who volunteer their time. If you are interested in sponsoring the GRASS Community Meeting, please see our

::: '''[https://opencollective.com/osgeo/projects/grass/contribute/grass-community-meeting-prague-2023-55074 OpenCollective GRASS Community Meeting Prague 2023 Tier]'''

Any surplus at the end of the event will used for future activities of the GRASS GIS project such as the successful [[Student Grants|student mini grant program]].

This GRASS Community Meeting is a great occasion for you to support the development of GRASS. With your contribution you'll enable more developers to meet. Community meetings are important opportunities for developers to discuss, fix bugs, plan the direction for the project and work on new features. Please see below for the detailed agenda. The developers and contributors are donating their valuable time, so it would be great if in-kind funding can be made available from within the community to cover out-of-pocket expenses. All of the work that takes place at the community meeting will be directly contributed back into the GRASS project to the benefit of everyone who uses it.

=== Thanks to our sponsors ===

== FAQ ==

* '''How was it last time?'''
** Very nice, see [[GRASS_GIS at OSGeo Virtual Community Sprint 2020]]!
* ''Is the GRASS Community Meeting just a coding event?''
** It is mainly a coding and documentation event. It is a working session for people who are already participants in the GRASS project and/or are committed to improving the GRASS project.
** On demand we can do some presentations of current working GRASS implementation and new upcoming features to spread the idea of Open Source GIS software.
* ''Is the GRASS Community Meeting for developers only?''
** No: anybody can help, with testing, checking out bugs and fixes, documentation and more.
* ''Where can I get help and more information about the community meeting?''
** Contact [[User:Landa|Martin Landa]] <tt><landa.martin at gmail.com></tt>

== Report and press release ==

TBD: After the event :-)

We'll esp. craft a report for our sponsors.

== FAQ ==

* '''How was it last time?'''
** Very nice, see [[GRASS_GIS at OSGeo Virtual Community Sprint 2020]]!
* ''Is the GRASS Community Meeting just a coding event?''
** It is mainly a coding and documentation event. It is a working session for people who are already participants in the GRASS project and/or are committed to improving the GRASS project.
** On demand we can do some presentations of current working GRASS implementation and new upcoming features to spread the idea of Open Source GIS software.
* ''Is the GRASS Community Meeting for developers only?''
** No: anybody can help, with testing, checking out bugs and fixes, documentation and more.
* ''Where can I get help and more information about the community meeting?''
** Contact [[User:Landa|Martin Landa]] <tt><landa.martin at gmail.com></tt>

== Report and press release ==

TBD: After the event :-)

We'll esp. craft a report for our sponsors.

{{toc|right}}
The GRASS GIS team is organizing the ''GRASS GIS Community Meeting with contributors, power users and developers'' from '''June 2 to June 6, 2023''' to celebrate GRASS GIS '''40th birthday''' (by contributing to GRASS GIS of course).

<gallery mode="slideshow">
Image:grass-sprint-prague.jpg|Prague 2013
Image:Grass_sprint2018_bonn_fotowall.jpg|Bonn 2018
</gallery>

== Purpose ==

GRASS GIS Community Meeting is a great occasion for folks to support the development by actively contributing to the source code, documentation (manuals, wiki, tutorials), translations, website or likewise. The '''community''' meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS GIS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and desiring to '''celebrate with us the 40th GRASS GIS birthday!!'''

In this meeting, we will work on GRASS GIS and integrations with related OSGeo projects. We will revise connection to QGIS to make it easier to maintain, and we will work on migration of the build to CMake to improve Windows builds including PDAL support. Furthermore, we will start moving documentation to Markdown to make it easier to contribute to and we will add images and examples for tools and workflows which still miss them. Finally, we will automate and document maintenance processes to reduce the burden on maintainers and thus improve the project sustainability.

Note that while we have our general plan, we can't accept any earmarked donations, i.e., we can't make any promises for a specific work to be done. We do require participants to work on GRASS GIS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project at that time given their skills and time available.

For the detailed agenda and individual's plans, see below.

== Sponsors ==

We welcome '''financial contributions''' to support the meeting and we are looking for sponsors to cover costs such as meals or to help reducing travel and accommodation expenses for GRASS developers who volunteer their time. If you are interested in sponsoring the GRASS Community Meeting, please see our

::: '''[https://opencollective.com/osgeo/projects/grass/contribute/grass-community-meeting-prague-2023-55074 OpenCollective GRASS Community Meeting Prague 2023 Tier]'''

Any surplus at the end of the event will used for future activities of the GRASS GIS project such as the successful [[Student Grants|student mini grant program]].

This GRASS Community Meeting is a great occasion for you to support the development of GRASS. With your contribution you'll enable more developers to meet. Community meetings are important opportunities for developers to discuss, fix bugs, plan the direction for the project and work on new features. Please see below for the detailed agenda. The developers and contributors are donating their valuable time, so it would be great if in-kind funding can be made available from within the community to cover out-of-pocket expenses. All of the work that takes place at the community meeting will be directly contributed back into the GRASS project to the benefit of everyone who uses it.

=== Thanks to our sponsors ===

We are grateful for the support which we have received to organize this GRASS Community Meeting:

Financial support: (partial) travel grants can be payed upon request thanks to our sponsors!

== Agenda - What we plan to do ==

'''Note:''' The program is generally open for your ideas. Please write an email to the [http://lists.osgeo.org/mailman/listinfo/grass-dev GRASS developer list] to discuss your contribution.

During the meeting we will work on GRASS GIS on these tasks (please add more!):

* We will update and revise the [https://github.com/qgis/QGIS/tree/master/python/plugins/grassprovider GRASS GIS Integration with QGIS] to simplify maintenance.
* Furthermore, we will migrate the compilation technology to CMake to significantly improve the Windows builds including PDAL support and become binary compatible with OSGeo4W.
* The extensive GRASS documentation will be converted from HTML to Markdown to facilitate future collaboration.
* Pictures, examples and workflows will be added to the documentation where they are still missing.
* Software maintenance processes are automated and documented to reduce the burden on maintainers and thus improve the sustainability of the project.

This means that there are tasks from both the programming and documentation areas to appeal to a wide range of interested parties.

{{toc|right}}
The GRASS GIS team is organizing the ''GRASS GIS Community Meeting with contributors, power users and developers'' from '''June 2 to June 6, 2023''' to celebrate GRASS GIS '''40th birthday''' (by contributing to GRASS GIS of course).

</gallery>

== Purpose ==

GRASS GIS Community Meeting is a great occasion for folks to support the development by actively contributing to the source code, documentation (manuals, wiki, tutorials), translations, website or likewise. The '''community''' meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS GIS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and desiring to '''celebrate with us the 40th GRASS GIS birthday!!'''

In this meeting, we will work on GRASS GIS and integrations with related OSGeo projects. We will revise connection to QGIS to make it easier to maintain, and we will work on migration of the build to CMake to improve Windows builds including PDAL support. Furthermore, we will start moving documentation to Markdown to make it easier to contribute to and we will add images and examples for tools and workflows which still miss them. Finally, we will automate and document maintenance processes to reduce the burden on maintainers and thus improve the project sustainability.

Note that while we have our general plan, we can't accept any earmarked donations, i.e., we can't make any promises for a specific work to be done. We do require participants to work on GRASS GIS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project at that time given their skills and time available.

For the detailed agenda and individual's plans, see below.

== Sponsors ==

We welcome '''financial contributions''' to support the meeting and we are looking for sponsors to cover costs such as meals or to help reducing travel and accommodation expenses for GRASS developers who volunteer their time. If you are interested in sponsoring the GRASS Community Meeting, please see our

::: '''[https://opencollective.com/osgeo/projects/grass/contribute/grass-community-meeting-prague-2023-55074 OpenCollective GRASS Community Meeting Prague 2023 Tier]'''

Any surplus at the end of the event will used for future activities of the GRASS GIS project such as the successful [[Student Grants|student mini grant program]].

This GRASS Community Meeting is a great occasion for you to support the development of GRASS. With your contribution you'll enable more developers to meet. Community meetings are important opportunities for developers to discuss, fix bugs, plan the direction for the project and work on new features. Please see below for the detailed agenda. The developers and contributors are donating their valuable time, so it would be great if in-kind funding can be made available from within the community to cover out-of-pocket expenses. All of the work that takes place at the community meeting will be directly contributed back into the GRASS project to the benefit of everyone who uses it.

=== Thanks to our sponsors ===

We are grateful for the support which we have received to organize this GRASS Community Meeting:

== Agenda - What we plan to do ==

'''Note:''' The program is generally open for your ideas. Please write an email to the [http://lists.osgeo.org/mailman/listinfo/grass-dev GRASS developer list] to discuss your contribution.

During the meeting we will work on GRASS GIS on these tasks (please add more!):

* We will update and revise the [https://github.com/qgis/QGIS/tree/master/python/plugins/grassprovider GRASS GIS Integration with QGIS] to simplify maintenance.
* Furthermore, we will migrate the compilation technology to CMake to significantly improve the Windows builds including PDAL support and become binary compatible with OSGeo4W.
* The extensive GRASS documentation will be converted from HTML to Markdown to facilitate future collaboration.
* Pictures, examples and workflows will be added to the documentation where they are still missing.
* Software maintenance processes are automated and documented to reduce the burden on maintainers and thus improve the sustainability of the project.

This means that there are tasks from both the programming and documentation areas to appeal to a wide range of interested parties.

GRASS Community Meeting Prague 2023

2023-06-03T08:09:44Z

⚠️Chaedrich: /* Photos */

{{toc|right}}
The GRASS GIS team is organizing the ''GRASS GIS Community Meeting with contributors, power users and developers'' from '''June 2 to June 6, 2023''' to celebrate GRASS GIS '''40th birthday''' (by contributing to GRASS GIS of course).

<gallery mode="slideshow">
Image:grass-sprint-prague.jpg|Prague 2013
Image:Grass_sprint2018_bonn_fotowall.jpg|Bonn 2018
</gallery>

== Purpose ==

GRASS GIS Community Meeting is a great occasion for folks to support the development by actively contributing to the source code, documentation (manuals, wiki, tutorials), translations, website or likewise. The '''community''' meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS GIS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and desiring to '''celebrate with us the 40th GRASS GIS birthday!!'''

In this meeting, we will work on GRASS GIS and integrations with related OSGeo projects. We will revise connection to QGIS to make it easier to maintain, and we will work on migration of the build to CMake to improve Windows builds including PDAL support. Furthermore, we will start moving documentation to Markdown to make it easier to contribute to and we will add images and examples for tools and workflows which still miss them. Finally, we will automate and document maintenance processes to reduce the burden on maintainers and thus improve the project sustainability.

Note that while we have our general plan, we can't accept any earmarked donations, i.e., we can't make any promises for a specific work to be done. We do require participants to work on GRASS GIS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project at that time given their skills and time available.

For the detailed agenda and individual's plans, see below.

== Sponsors ==

We welcome '''financial contributions''' to support the meeting and we are looking for sponsors to cover costs such as meals or to help reducing travel and accommodation expenses for GRASS developers who volunteer their time. If you are interested in sponsoring the GRASS Community Meeting, please see our

Any surplus at the end of the event will used for future activities of the GRASS GIS project such as the successful [[Student Grants|student mini grant program]].

This GRASS Community Meeting is a great occasion for you to support the development of GRASS. With your contribution you'll enable more developers to meet. Community meetings are important opportunities for developers to discuss, fix bugs, plan the direction for the project and work on new features. Please see below for the detailed agenda. The developers and contributors are donating their valuable time, so it would be great if in-kind funding can be made available from within the community to cover out-of-pocket expenses. All of the work that takes place at the community meeting will be directly contributed back into the GRASS project to the benefit of everyone who uses it.

=== Thanks to our sponsors ===

'''Note:''' The program is generally open for your ideas. Please write an email to the [http://lists.osgeo.org/mailman/listinfo/grass-dev GRASS developer list] to discuss your contribution.

During the meeting we will work on GRASS GIS on these tasks (please add more!):

* We will update and revise the [https://github.com/qgis/QGIS/tree/master/python/plugins/grassprovider GRASS GIS Integration with QGIS] to simplify maintenance.
* Furthermore, we will migrate the compilation technology to CMake to significantly improve the Windows builds including PDAL support and become binary compatible with OSGeo4W.
* The extensive GRASS documentation will be converted from HTML to Markdown to facilitate future collaboration.
* Pictures, examples and workflows will be added to the documentation where they are still missing.
* Software maintenance processes are automated and documented to reduce the burden on maintainers and thus improve the sustainability of the project.

This means that there are tasks from both the programming and documentation areas to appeal to a wide range of interested parties.

== FAQ ==

* '''How was it last time?'''
** Very nice, see [[GRASS_GIS at OSGeo Virtual Community Sprint 2020]]!
* ''Is the GRASS Community Meeting just a coding event?''
** It is mainly a coding and documentation event. It is a working session for people who are already participants in the GRASS project and/or are committed to improving the GRASS project.
** On demand we can do some presentations of current working GRASS implementation and new upcoming features to spread the idea of Open Source GIS software.
* ''Is the GRASS Community Meeting for developers only?''
** No: anybody can help, with testing, checking out bugs and fixes, documentation and more.
* ''Where can I get help and more information about the community meeting?''
** Contact [[User:Landa|Martin Landa]] <tt><landa.martin at gmail.com></tt>

== Report and press release ==

TBD: After the event :-)

We'll esp. craft a report for our sponsors.

GRASS Community Meeting Prague 2023

2023-06-03T08:04:17Z

⚠️Chaedrich: /* Photos */

{{toc|right}}
The GRASS GIS team is organizing the ''GRASS GIS Community Meeting with contributors, power users and developers'' from '''June 2 to June 6, 2023''' to celebrate GRASS GIS '''40th birthday''' (by contributing to GRASS GIS of course).

<gallery mode="slideshow">
Image:grass-sprint-prague.jpg|Prague 2013
Image:Grass_sprint2018_bonn_fotowall.jpg|Bonn 2018
</gallery>

== Purpose ==

GRASS GIS Community Meeting is a great occasion for folks to support the development by actively contributing to the source code, documentation (manuals, wiki, tutorials), translations, website or likewise. The '''community''' meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS GIS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and desiring to '''celebrate with us the 40th GRASS GIS birthday!!'''

In this meeting, we will work on GRASS GIS and integrations with related OSGeo projects. We will revise connection to QGIS to make it easier to maintain, and we will work on migration of the build to CMake to improve Windows builds including PDAL support. Furthermore, we will start moving documentation to Markdown to make it easier to contribute to and we will add images and examples for tools and workflows which still miss them. Finally, we will automate and document maintenance processes to reduce the burden on maintainers and thus improve the project sustainability.

Note that while we have our general plan, we can't accept any earmarked donations, i.e., we can't make any promises for a specific work to be done. We do require participants to work on GRASS GIS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project at that time given their skills and time available.

For the detailed agenda and individual's plans, see below.

== Sponsors ==

We welcome '''financial contributions''' to support the meeting and we are looking for sponsors to cover costs such as meals or to help reducing travel and accommodation expenses for GRASS developers who volunteer their time. If you are interested in sponsoring the GRASS Community Meeting, please see our

::: '''[https://opencollective.com/osgeo/projects/grass/contribute/grass-community-meeting-prague-2023-55074 OpenCollective GRASS Community Meeting Prague 2023 Tier]'''

== FAQ ==

* '''How was it last time?'''
** Very nice, see [[GRASS_GIS at OSGeo Virtual Community Sprint 2020]]!
* ''Is the GRASS Community Meeting just a coding event?''
** It is mainly a coding and documentation event. It is a working session for people who are already participants in the GRASS project and/or are committed to improving the GRASS project.
** On demand we can do some presentations of current working GRASS implementation and new upcoming features to spread the idea of Open Source GIS software.
* ''Is the GRASS Community Meeting for developers only?''
** No: anybody can help, with testing, checking out bugs and fixes, documentation and more.
* ''Where can I get help and more information about the community meeting?''
** Contact [[User:Landa|Martin Landa]] <tt><landa.martin at gmail.com></tt>

GRASS Community Meeting Prague 2023

2023-06-03T08:03:45Z

⚠️Chaedrich: /* Photos */

{{toc|right}}
The GRASS GIS team is organizing the ''GRASS GIS Community Meeting with contributors, power users and developers'' from '''June 2 to June 6, 2023''' to celebrate GRASS GIS '''40th birthday''' (by contributing to GRASS GIS of course).

</gallery>

== Purpose ==

GRASS GIS Community Meeting is a great occasion for folks to support the development by actively contributing to the source code, documentation (manuals, wiki, tutorials), translations, website or likewise. The '''community''' meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS GIS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and desiring to '''celebrate with us the 40th GRASS GIS birthday!!'''

In this meeting, we will work on GRASS GIS and integrations with related OSGeo projects. We will revise connection to QGIS to make it easier to maintain, and we will work on migration of the build to CMake to improve Windows builds including PDAL support. Furthermore, we will start moving documentation to Markdown to make it easier to contribute to and we will add images and examples for tools and workflows which still miss them. Finally, we will automate and document maintenance processes to reduce the burden on maintainers and thus improve the project sustainability.

Note that while we have our general plan, we can't accept any earmarked donations, i.e., we can't make any promises for a specific work to be done. We do require participants to work on GRASS GIS or connections to other projects. However, we leave them the freedom to work on what they think is the best contribution to the project at that time given their skills and time available.

For the detailed agenda and individual's plans, see below.

== Sponsors ==

We welcome '''financial contributions''' to support the meeting and we are looking for sponsors to cover costs such as meals or to help reducing travel and accommodation expenses for GRASS developers who volunteer their time. If you are interested in sponsoring the GRASS Community Meeting, please see our

::: '''[https://opencollective.com/osgeo/projects/grass/contribute/grass-community-meeting-prague-2023-55074 OpenCollective GRASS Community Meeting Prague 2023 Tier]'''

Any surplus at the end of the event will used for future activities of the GRASS GIS project such as the successful [[Student Grants|student mini grant program]].

This GRASS Community Meeting is a great occasion for you to support the development of GRASS. With your contribution you'll enable more developers to meet. Community meetings are important opportunities for developers to discuss, fix bugs, plan the direction for the project and work on new features. Please see below for the detailed agenda. The developers and contributors are donating their valuable time, so it would be great if in-kind funding can be made available from within the community to cover out-of-pocket expenses. All of the work that takes place at the community meeting will be directly contributed back into the GRASS project to the benefit of everyone who uses it.

=== Thanks to our sponsors ===

We are grateful for the support which we have received to organize this GRASS Community Meeting:

== Agenda - What we plan to do ==

'''Note:''' The program is generally open for your ideas. Please write an email to the [http://lists.osgeo.org/mailman/listinfo/grass-dev GRASS developer list] to discuss your contribution.

During the meeting we will work on GRASS GIS on these tasks (please add more!):

* We will update and revise the [https://github.com/qgis/QGIS/tree/master/python/plugins/grassprovider GRASS GIS Integration with QGIS] to simplify maintenance.
* Furthermore, we will migrate the compilation technology to CMake to significantly improve the Windows builds including PDAL support and become binary compatible with OSGeo4W.
* The extensive GRASS documentation will be converted from HTML to Markdown to facilitate future collaboration.
* Pictures, examples and workflows will be added to the documentation where they are still missing.
* Software maintenance processes are automated and documented to reduce the burden on maintainers and thus improve the sustainability of the project.

This means that there are tasks from both the programming and documentation areas to appeal to a wide range of interested parties.

== Purpose ==

GRASS GIS Community Meeting is a great occasion for folks to support the development by actively contributing to the source code, documentation (manuals, wiki, tutorials), translations, website or likewise. The '''community''' meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS GIS project and the interfaces to QGIS, GDAL, PostGIS, R, OGC Services and desiring to '''celebrate with us the 40th GRASS GIS birthday!!'''

In this meeting, we will work on GRASS GIS and integrations with related OSGeo projects. We will revise connection to QGIS to make it easier to maintain, and we will work on migration of the build to CMake to improve Windows builds including PDAL support. Furthermore, we will start moving documentation to Markdown to make it easier to contribute to and we will add images and examples for tools and workflows which still miss them. Finally, we will automate and document maintenance processes to reduce the burden on maintainers and thus improve the project sustainability.

Note that while we have our general plan, we can't accept any earmarked donations, i.e., we can't make any promises for a specific work to be done.

GRASS Community Meeting Prague 2023

2023-04-25T14:59:15Z

⚠️Chaedrich:

{{toc|right}}
The GRASS GIS team is organizing the ''GRASS GIS Community Meeting with contributors, power users and developers'' from '''June 2 to June 6, 2023''' to celebrate GRASS GIS '''40th birthday'''.

<gallery mode="slideshow">
Image:grass-sprint-prague.jpg|Prague 2013
Image:Grass_sprint2018_bonn_fotowall.jpg|Bonn 2018
</gallery>

== Purpose ==

GRASS GIS Community Meeting is a great occasion for folks to support the development by actively contributing to the source code, documentation (manuals, wiki, tutorials), translations, website or likewise. The '''community''' meeting is also a get-together where supporters, contributors, power users and developers make decisions and tackle larger problems related to the project, discuss and collaboratively resolve bugs, plan the direction for the project and work on new features. We welcome people committed to improving the GRASS GIS project and the interfaces to QGIS, GDAL, PostGIS, R statistics, OGC Services and willing to '''celebrate with us the 40th GRASS GIS birthday!!'''

For the detailed agenda, see below.

== Sponsors ==

We welcome '''financial contributions''' to support the meeting and we are looking for sponsors to cover costs such as meals or to help reducing travel and accommodation expenses for GRASS developers who volunteer their time. If you are interested in sponsoring the GRASS Community Meeting, please see our

::: '''[https://opencollective.com/osgeo/projects/grass/contribute/grass-community-meeting-prague-2023-55074 OpenCollective GRASS Community Meeting Prague 2023 Tier]'''

Any surplus at the end of the event will used for future activities of the GRASS GIS project such as the successful [[Student Grants|student mini grant program]].

This GRASS Community Meeting is a great occasion for you to support the development of GRASS. With your contribution you'll enable more developers to meet. Community meetings are important opportunities for developers to discuss, fix bugs, plan the direction for the project and work on new features. Please see below for the detailed agenda. The developers and contributors are donating their valuable time, so it would be great if in-kind funding can be made available from within the community to cover out-of-pocket expenses. All of the work that takes place at the community meeting will be directly contributed back into the GRASS project to the benefit of everyone who uses it.

=== Thanks to our sponsors ===

== Accommodation and Costs ==

Participants should plan for the following costs:

* The participation is free of charge
* Travel to Prague, variable depending on where you come from, reimbursements depending on the financial contributions provided by the community
* Accommodation and meals (with the donated sponsorship money we will try to cover some expenses of the participants)
'''Please note''': The currency in Czech Republic is {{wikipedia|Czech crown}} (CZK, koruna, Kč). 100 Czech crowns are about 4 Euros (see [https://www.cnb.cz/cs/financni-trhy/devizovy-trh/kurzy-devizoveho-trhu/kurzy-devizoveho-trhu/ current rates]).

Please let us know your time of arrival and departure, so we can book accommodations and organize the logistics.

Financial support: (partial) travel grants can be payed upon request thanks to our sponsors!

== Agenda - What we plan to do ==

'''Note:''' The program is generally open for your ideas. Please write an email to the [http://lists.osgeo.org/mailman/listinfo/grass-dev GRASS developer list] to discuss your contribution.

During the meeting we will work on GRASS GIS on these tasks (please add more!):

* We will update and revise the [https://github.com/qgis/QGIS/tree/master/python/plugins/grassprovider GRASS GIS Integration with QGIS] to simplify maintenance.
* Furthermore, we will migrate the compilation technology to CMake to significantly improve the Windows builds including PDAL support and become binary compatible with OSGeo4W.
* The extensive GRASS documentation will be converted from HTML to Markdown to facilitate future collaboration.
* Pictures, examples and workflows will be added to the documentation where they are still missing.
* Software maintenance processes are automated and documented to reduce the burden on maintainers and thus improve the sustainability of the project.

This means that there are tasks from both the programming and documentation areas to appeal to a wide range of interested parties.

Further details about the action items you '''find [[Talk:GRASS Community Meeting Prague 2023|here]]''' and below. Topics cover non-technical, semi-technical, and technical issues.
