GRASS 7 Release Planning

• Release scope: new display architecture, new raster library, new features such as temporal data handling...
• The SVN trunk corresponds to GRASS 7 (for access, see here)
• ​http://grass.osgeo.org/wiki/GRASS_7_ideas_collection (to be merged into trac)

Already implemented

• New features in version 7.0 (already implemented)
• 3D raster library and modules in version 7 (finished)
• ​Introduction of temporal modules | ​Available temporal modules | ​Tutorials (user contributed content)
• New features in version 7.2
• New features in version 7.4

Planning & ongoing

Source code changes:

• Display library in GRASS 7 (planning & ongoing)
• Raster library in GRASS 7 (planning & ongoing)
• Vector library in GRASS 7 (planning & ongoing)
• Temporal extension for GRASS 7 (core functions are implemented, ongoing improvement)
  • ​Temporal Library API
  • Temporal GIS Algebra for Raster and Vector Data GSoC project 2013

Documentation

• Use Sphinx for Python API (complete?) (done)
• Documentation: update HTML manual pages to more recent technology (see examples by Vaclav Petras) and #151

Trunk

• NULL compression, make default ~and backport to 7.0 for compatibility~
• RLE/DEFLATE/LZ4 compression: #2750: LZ4 when writing raster rows; better than double I/O bound r.mapcalc speed
• r.mapcalc / r3.mapcalc: new variables to access current region dimensions in cells (nrows, ncols, ndepths) (r67664)

7.2.2 (to be backported)

• vector modules: Added layer specific database information to v.info extended metadata flag: r69535
• i18N: Install gettext to Python script modules to use translated strings extracted by r70817: r70818
• ~v.what.strds: add capabilities to use names also for temporal dataset with minutes and seconds granularity: r69331~
• v.in.lidar: r70134 (done)
• d.linegraph: a series of improvements, see ​https://trac.osgeo.org/grass/log/grass/trunk/display/d.linegraph/main.c (wenzeslaus: most are improvements/features, a lot of code changed, leaving it for 7.4)
• i.atcorr: Sentinel-2A r70161 (Test feedback in ML needed first)
• r.grow.distance: clean up after r68611: r69327
• r.in.lidar: Storage type (wenzeslaus: not sure what it is, but code is not identical in 7.2 and trunk)
• r.in.xyz: unify keywords and method descriptions with r.in.lidar (r68596): r68600 (done in r71300 and r70291)
• lib/python/temporal: major differences to be checked TODO
• r.in.srtm: Print an error instead of failing in a XY location: r70819

7.2.3 (to be backported)

Addon candidate to be moved to trunk

Comment from Moritz: At one point we said that only addons that have tests should go into core. AFAICS, none of the below have tests...

Interesting:

• G7A:r.geomorphon
• G7A:r.object.geometry - +/- equivalent to v.to.db, but for raster objects: very useful for many other modules (notably OBIA)
• G7A:r.vect.stats - very simple, but nice functionality to have in core
• G7A:v.centerpoint - basic GIS functionality
• G7A:v.clip - very easy to use and expected GIS functionality without hassle of complicated commmands :-)
• G7A:v.profile - expected GIS functionality

Maybe, if stable enough

• G7A:v.concave.hull
• G7A:v.kriging

General strategy

... regular publication of stability releases:

7.0.x ... 7.0.1 ... 7.0.0:

• all released, see Release

Historical notes

• a releasebranch_6_4 branch has been created (for access, see here) - used to release GRASS GIS 6.4.x
• a develbranch_6 branch has been created (for access, see here) - unused since 2015
• trunk has become GRASS 7.1.svn
• branches/releasebranch_7_0 has become GRASS 7.0.svn
• ​Announcement (2008, GRASS 7 development started)
• GRASS GIS 6.3.0 has been released from the releasebranch_6_3 branch
