Line 81: Line 57:
The '''GRASS GIS Layer Manager''' provides an interactive graphical interface to GRASS commands. The Layer Manager includes a set of pull-down menus for all GRASS GIS functions (analysis, file I/O, GIS configuration and management), toolbar that manage display map layers in map display windows, layer tree in which map layers to display are organized, command output window and integrated command line prompt.

=== Map display window ===
* see [[Importing data]]


'''Status:''' prototype implemented.
==== Map display window ====


Each '''Map display window''' has a unique set of layers to display and region setting (zoom). The map display window includes main toolbar with basic tools including zooming, panning, data querying, simple analyse functions (measure, profile, histogram, etc.), overlay management, etc. From main toolbar are accessible additional toolbars, currently only Digitization tool is available. Under development is Georectification tool.

: Probably write a front end for {{cmd|r.in.poly}}, that's all the old {{cmd|r.digit}} is.
* {{cmd|d.rast.edit}}
: Idea: get cell center coords and new values from GUI interaction, then pass those through {{cmd|r.in.xyz}}, and {{cmd|r.patch}} the new values over the top of the old map.

'''Status:''' development not started yet.
[[Image:D_rast_edit_grass7.png|center|thumb|500px|Raster map editor in GRASS 7]]


==== GUI for ps.map ====
* merge with Georectifier? (i.points, i.vpoints)


* [http://grass.osgeo.org/grass63/manuals/html63_user/ps.map.html ps.map] is a cartographic composer, intended to be a stand-alone hardcopy plot generator. It is not meant to be a '''Print''' button for the maps currently displayed in the map canvas, that will need it own controls.
===== Category Labels =====


* The GUI will prepare a semi-WYSIWYG + tree menu controls which can write a ps.map control file, and then run ps.map to create PostScript and PDF output directly. Loading a ps.map control file is harder and can happen later.
* Write with new {{cmd|r.category}} import tool
** ''Back-end component complete: {{cmd|r.category}} module is now updated to handle a rules= file and other goodies like dynamic labels''


* For a start at a Tcl/Tk composer see gui/tcltk/d.m/print.tcl
* Read with one of {{cmd|r.category}}, {{cmd|r.describe}}, {{cmd|r.report}}, {{cmd|r.stats}}, ???
: see also these discussions and pyGTK prototype by Jachym Cepicky
** probably need to add a new flag to one of those to print flat <tt>"%d %s", cat, label</tt>
:* http://thread.gmane.org/gmane.comp.gis.grass.devel/12469
: or read the cats/ file directly, it's already flat ascii.
:* http://thread.gmane.org/gmane.comp.gis.grass.devel/19368
* how to deal with FP maps & cats?


* Start with most important mapping instructions
=== Command line ===
** paper
** scale
** maploc
** rast
** vects
** grids
** scalebar
** mapinfo
** text labels


===== Intelligent label placement in ps.map =====
In order to provide a command line in all operating systems, there is a tab "Command console" available (with auto-completion support). It communicates directly with the Map Display window:


* use PAL/JPAL [http://geosysin.iict.ch/PAL cartographic labelling library] (GPL, C++ language, JNI wrapper)
[[Image:Wxgui command line.png|350px|center|Command line]]


===== Outputs =====
=== Cartography tools ===


* ps.map instructions file
==== GUI for {{Cmd|ps.map}} ====
* PostScript file [ps.map instructions tmp file]
* lpr [PostScript tmp file]
* PDF File (pstopdf? ps2pdf? GNU Ghostscript?) [PostScript tmp file]


===== Inputs =====
'''Status:''' under development (Anna Kratochvilova).


* Ability to load in saved ps.map scripts. I consider this to be a low priority, deal with it after map creation is fully functional. Start with scripts saved using the GUI, after that is working expand to load any ps.map instructions file.
Note: More info at '''[[WxGUI Cartographic Composer]]'''

Layer Manager

Status: prototype implemented.

The GRASS GIS Layer Manager provides an interactive graphical interface to GRASS commands. The Layer Manager includes a set of pull-down menus for all GRASS GIS functions (analysis, file I/O, GIS configuration and management), toolbar that manage display map layers in map display windows, layer tree in which map layers to display are organized, command output window and integrated command line prompt.

Import tool

The GUI offers a convenient tool for single map and bulk import:

Map display window

Each Map display window has a unique set of layers to display and region setting (zoom). The map display window includes main toolbar with basic tools including zooming, panning, data querying, simple analyse functions (measure, profile, histogram, etc.), overlay management, etc. From main toolbar are accessible additional toolbars, currently only Digitization tool is available. Under development is Georectification tool.

Map query tool

Raster and vector maps can be queried at cursor position:

Raster and vector map query (select map to query in layer manager)

Map measure tool

Raster and vector maps can be measured with a digitizer (line or self-closing area).

Note for LatLong locations: The lengths/areas are returned also in metric units.

Measurements of line length and area size (latitude-longitude location example with SRTM

GUI dialogs

Status: prototype implemented.

Generated from XML using --interface-description.

E.g. d.rgb --help 

Description:

Raster digitizer

Status: development started in GRASS 7 (2014) --> implemented in 2020

Probably write a front end for r.in.poly, that's all the old r.digit is.
Idea: get cell center coords and new values from GUI interaction, then pass those through r.in.xyz, and r.patch the new values over the top of the old map.
Current status:
Raster map editor in GRASS 7
  • merge with Georectifier? (i.points, i.vpoints)
Category Labels
  • Write with new r.category import tool
    • Back-end component complete: r.category module is now updated to handle a rules= file and other goodies like dynamic labels
or read the cats/ file directly, it's already flat ascii.
  • how to deal with FP maps & cats?

Command line

In order to provide a command line in all operating systems, there is a tab "Command console" available (with auto-completion support). It communicates directly with the Map Display window:

Help browser

Status: development not started yet.

For browsing manual pages is currently used web browser, the goal is to design integrated help system.

HB: We used to have one of these for viewing the help pages of Tcl/Tk NVIZ. We dropped it because it was a pain to maintain and generally outside our core mission so a distraction.

Known issues

Platform specific

For the GUI to know what platform it's on, and therefore apply platform specific commands (e.g. append '.exe' to programs) it has to test what platform it is running on. Here we take the experimental approach to learning what's best to use. Please add or generalize this list as you can.

Platform information - start Python from the command line then issue 

 import sys
 sys.platform
 
 import os
 os.name
 os.environ['OS']
 
 import platform
 platform.system()

Right now the GUI only runs 32bit, even if the rest of GRASS is 64bit, because it's not yet possible for wxPython to be 64bit. It comes out the same as PPC 32bit - no distinction between ppc/intel or 32/64 bit, it's all darwin. (yes, I checked, and I have a custom 64bit python executable to verify)

General GUI Design

Layout

For some users, the current approach of separate windows (SDI) leads to a windows flooding. Especially on large monitors or dual screen systems catching the wxGUI windows can be tedious when they appear on separate monitors (depends on windows manager, the much used KDE scatters typically the wxGUI windows all over the screen real estate). Almost each task generates a new wxGUI window which is freely floating around on the screen: example 1 and example 2. On a dual-screen this may sum up to 50cm of distance!

Proposed solutions:

  • implement optional layout similar to QGIS (with a legend attached to each display) or GSDView etc) (see figure below)
  • implement optional magnetic docking of the layer manager and display windows to keep the windows closer
  • do not allow module windows to stay open. That is, get rid of the apply button and force each window to close when OK is pressed (QGIS/ArcGIS approach). This leaves only the display(s) and single legend/layer manager on desktop.
  • If you otherwise wish to continue using your current WM, file a bug report with them asking for better multi-head support and get the problem fixed at the source. (there probably already is a bug filed with tips in it)
Current wxGUI layout with detached window components
Proposal for wxGUI layout modification (Recomposition of existing toolbars, mapview and menus)

New solution: see WxGUI#Data_Catalog above.


What others do

SDI: (each document opened in application occupies a window on the desktop)

  • GRASS: display window for each document (i.e., set of maps displayed) opened on desktop; one legend/layer manager window for all display windows; ; each module/function opens a separate window on the desktop
  • QGIS: display window for each document (i.e., set of maps displayed) opened on the desktop; legend/layer manager window attached to each display window; each module/function opens a separate window on the desktop (e.g. http://grass.osgeo.org/grass61/screenshots/images/qgis08_grass6_toolbox.png)
  • ArcGIS: similar to QGIS with combined legend/display for each document (set of maps displayed); each module/function opens a separate window on the desktop (e.g. http://upload.wikimedia.org/wikipedia/en/9/92/ArcMap.jpg)
  • MapInfo (pre Pitney Bowes): each document opens a map display window on the desktop; single legend/toolbox opened on the desktop controls all visible documents (i.e., map displays); each module/function opens a separate window on the desktop (similar to current GRASS layout)
