Participant comments and plans

...

Joint efforts

(see here for participants' names)

  • Creating 3D vector test data (for 3D interpolation) - ES, SG, MN
  • Added General introduction (based on manual of G7/i.vi by Yann Chemin) - MN, MN, YC
  • Discussions on Bundle Block Adjustments - YC, ST
  • wxGUI refactoring - AP, VP
  • Presentation of state of image processing in GRASS 7 - YC, MN
  • Presentation of state of Temporal GIS Algebra in GRASS 7 - SG, TL
  • ISIS-GRASS bridge port to GRASS7 - YC, VP, ML, MN
  • Discussions on potential integration of Rasdaman software as raster data backend - SG, YC, and Jachym (virtually)
  • Presentation on vector conflation - TF with discussion
  • ...

Individual Reports

Here the (very incomplete) list of individual efforts:

Martin Landa

  • Community Sprint organization
  • OSGeo4W GRASS 6.4.3RC4 package published
  • Fix v.pack on MS Windows, r57117
  • Fix v.unpack on MS Windows, r57121

Markus Neteler

Yann Chemin

  • ISIS-GRASS bridge port to GRASS7 (with Vaclav, Martin and MarkusN)
 If ISIS (http://isis.astrogeology.usgs.gov) is installed, 
 GRASS will load it in the background,
 the banner and prompt will change to ISIS-GRASS.
 Both ISIS and GRASS commands are available at the ISIS-GRASS prompt.
  • g.isis3mt exports a ISIS3 template from current location, ported into GRASS 7
  • Tested direct access of ISIS3 data into G7, r.in.gdal and r.external both work (tested Mars MOLA and Dawn test_datasets)
  • Discussed with Soeren, Vaclav and Jachym about Rasdaman, Voxel lib and Raster handling in Grass 8, we agreed on investigating handling, interfaces and performances.
  • Went through the Bundle Block Adjustment files with Stepan
  • Landsat 7 chain processing using pyGRASS goes in testing mode with MarkusN and Soeren
  • Worked more on r.crater

Margherita Di Leo

Markus Metz

  • r.stream.* modules: clean up before moving from addons to trunk r57151, r57152
  • GRASS wiki image processing update (MM, MN, YC)

Anne Ghisla aka aghisla

  • Google Summer of Code live discussions
  • v.krige fixed in G7 r57146 and following

Sören Gebbert aka huhabla

  • Google Summer of Code Temporal Algebra presentation and implementation support
  • Discussion of RASDAMAN GRASS integration
  • Discussion and implementation of the new temporal module t.rast.accumulate and the use of a modified version of r.gdd (implemented by Markus Metz) instead of r.mapcalc
  • Writing and updating of many temporal modules manual pages

Stepan Turek

  • Working on Google Summer of Code project
  • Went through the Bundle Block Adjustment files with Yann

Thomas Leppelt

  • Working on GSoC Project: Temporal Algebra
  • Implementing functions for if-statements in the temporal algebra

Milena Nowotarska

  • GUI translation to Polish

Anna Petrasova

  • attempts to compile wxPython with wxGTK3/Broadway (HTML5) backend, so far not successfull, see discussion
  • wxGUI refactoring
  • wxGUI design
  • toolboxes: discussion, adding <addons> tag

Vaclav Petras

  • compiling wxPython with wxGTK3/Broadway with Anna
  • discussion of Rasdaman GRASS integration
  • wxGUI refactoring
  • wxGUI design
  • toolboxes: discussion
  • ISIS-GRASS bridge port to GRASS7 with Yann

Eva Stopková

  • debug of plotting variogram output in module v.kriging (not published yet)
  • discussion about kriging methods in GRASS GIS with Anne

Video-conferencing options

Q: is Google Hangouts smartphones only?

not sure, but I'm pretty sure you can get a web browser plugin for all major desktop OSs

Q: do you have to be signed up with a Google+ social media account?

in theory no, but in practice they strongly funnel you that way

Q: is Jitsi on a desktop computer compatible with G+?

at the text chat level, yes. video and voice via Google Talk, reported to work with Voice, not sure about video
Jitsi
It is compatible with GoogleTalk instant messaging (and most other instant messaging including the XMPP RFC like Facebook; Skype is the notable one that it doesn't work with), not sure about GoogleTalk's voice calls, I'd give that a 80% chance of working.
An interesting side-project Jisti offers its own work-alike free multi-person video chat for XMPP(Jabber compatibles) which is not limited to 10 people: VideoBridge. Given enough bandwidth and a modern desktop CPU acting as the bridge server, you can have someone in a G+ hangout share their desktop to pass through the other members of the video hangout.
Also there's a functional alpha-release Android client.
For Jitsi <-> Jitsi video you may need a valid XMPP account. Many (federated in a single grid) providers for that, so it doesn't matter much who. Jitsi run a simple registry at http://jit.si
All quite interesting possiblies and the development is quite active -- but is it there yet? I'm not sure, probably a not far away "almost"; if so, perhaps we could run the bridge on Adhoc for a few days (can run as an unprivilidged user, needs Java 6, chat "host" user needs shell access to set magic pass word and get the assigned port numbers to plug into their client), or perhaps host it at fsv.cvut.cz? (i.e. locate it at the shortest hop to max number of participants using it) --HB
