GRASS 7 ideas collection
Raster
Library
- Split libgis into G_() part and Rast_() part
- Rewrite library from scratch. See suggestions
- Insert 'vertical' 2d rasters (e.g. geophysical survey data)
Modules
- Remove r.in.arc and r.out.arc, if a related bug in r.in.gdal is fixed. The integer/floating point detection for AAIGrid driver in GDAL was fixed after 1.3.2 release, so r.in.gdal and r.out.gdal should be enough now.
- Remove the code from r.info that makes it print projection information - we have g.region and g.proj for that. Moreover, r.info always prints a bogus (zone 0) information in non-UTM locations, which is confussing. See a bug report.
- fix the raster map history management (truncating long history, odd storage). It should work like for vector maps in GRASS 6.
- dispose r.resample and r.bilinear in favor of r.resamp.interp
- merge r.surf.idw and r.surf.idw2
- drop r.univar.sh; newly implemented r.univar features cover it
- drop r.univar.sh; newly implemented r.univar features cover it
- r.sum, r.mode, r.median, r.average, r.statistics, r.univar, r.univar2 - maybe they can be reduced to just r.statistics and r.univar? See RT #1848 and a thread on the GRASS dev list
- Dispose r.out.tiff. New C r.out.gdal should cover all it's option now (doublecheck!). See RT #3680 (starting with date Sun, Nov 26 2006 14:54:23).
- Remove remaining -v and -q flags for verbosity levels of modules.
- fix lseek() usage for Large File Support: see list of affected modules
Vector
Library
- 2d 'vertical' vector data (e.g. Geologic Cross Sections)
Modules
- rename v.mkgrid to v.grid
- merge v.select and v.overlay
- Remove doubled units in v.to.db GUI
- Fix the Column 'cat_' already exists (duplicate name) in v.in.ogr. Maybe by creating columns cat_1, cat_2 etc. each time a Grass vector is exported to shapefile and imported back to Grass?
- write Vect_map_exists() and implement in g.remove and v.digit -n (why wait for GRASS 7 ??)
- add '-d' dissolve to v.reclass
- add 'where=' to v.to.rast (why wait for GRASS 7 ??)
- implement Douglas-Peucker generalization (C code file)to substitute prune tool of v.clean (why wait for GRASS 7 ??)
General
Library
- Add support for planetary bodies reference systems
- Add new partial differential equation (PDE) library with OpenMP support
Modules
- g.remove, g.mremove, g.rename, g.copy: don't allow for default datatype (which is currently raster) [1].
Database
Library
Modules
Imagery
Library
Do merge of image libraries:
- A)
- lib/imagery/: standard lib, in use (i.* except for i.points3, i.rectify3)
- imagery/i.ortho.photo/libes/: standard lib, in use (i.ortho.photo, photo.*)
- B)
- lib/image3/: never finished improvement which integrated the standard lib and the ortho lib. Seems to provide also ortho rectification for satellite data (i.points3, i.rectify3)
Modules
- merge of i.points, i.vpoints, i.points3
- merge of i.rectify and i.rectify3
- addition of new resampling algorithms such as bilinear, cubic convolution (take from r.proj?)
- add other warping methods (maybe thin splines from GDAL?)
- implement/finish linewise ortho-rectification of satellite data
- Depreciate tape functions in next major revision of GRASS and create a tape module that accomplishes tape access.
Raster3D
Library
- renaming of all G3D library functions to fulfil the grass coding standard
- extent/rewrite documentation
- localisation support (why wait for GRASS 7 ??)
Modules
- report and support modules like r3.stats, r3.support
- voxel -> vector (isosurfaces ...) and vector -> voxel (lines, faces, volumes) conversion modules
- module for 3d Kriging interpolation based on vector points
- a GRASS-Python/VTK visualisation/manipulation tool
Display
Modules
- Huidae Cho merged d.text.freetype and d.text into d.text.new; drop them and rename d.text.new into d.text
- merge d.font and d.font.freetype too
Parser
- "Add another semantic meaning to the parser system for a type safe enumerated list" (Cedric's words commenting the bug that v.type doesn't allow for selecting input and output type in GUI
- Making GRASS modules be less verbose. Use --verbose flag and GRASS_VERBOSE environment variable. All output (G_message, G_percetn, G_warning) should go to GRASS_LOG file which could be grassdata/location/mapset/.grass.log by default.
Data management
- store vertical units on per-map base, using code from units software
- store vertical map datum on per-location base (GDAL/OGR needs the same enhancement)
- add versioning for maps (to recover previous map versions)
Time series
- Implement better Time series in GRASS support (series of satellite data etc)
Visualization
...
CLI
Fix the parameters and flags. Make it a concept. See proposal in GRASS 5 documents/parameter_proposal.txt
GUI
- Multiplatform
- Fast
- Small on monitor
- Number of window reduction
- Managable from command line via d.* modules (which will have to be rewritten too)
- Facilitating easy development of custom GUI application based on GRASS
- Python?
- WxWidgets?
- Qt4
Conceptual changes
- File organization in binaries:
- the grass etc dir is a mess... module should maintain arch-deps and arch-indep things in different paths -- frankie at #grass irc
- it's basically a FHS violation, i dunno if it is reported by lintian, anyway /usr/lib/grass should be used for arch-deps data, not for mixed stuff -- frankie at #grass irc
