Agenda
Community stuff:
Raster:
- discuss and ideally activate new raster compression scheme in "trunk" (trac #2750)
- code: lib/raster/init.c, line 124
- Plan:
- Null data are by default DEFLATE compressed: hence, if GRASS_COMPRESS_NULLS=1 or not defined at all. So, if the user sets GRASS_COMPRESS_NULLS to anything else than 1, Null data will not be compressed.
- Note: Backward NULL file compression compatibility could be implemented in relbranch70 only by ZLIB's DEFLATE (see https://trac.osgeo.org/grass/ticket/2750#comment:36). Hence ZLIB may qualify for the default NULL compression algorithm.
Projections:
- fix GDAL CSV: trac #2456
- EPSG: trac #2490
- revisit Even R's comments on this
Core:
- Kickstart of GRASS with LatLong predefined, open import wizard | switch projection
QA:
- integrate "coverity scan" with Travis, https://scan.coverity.com/travis_ci
- check "coverity scan": copy-paste errors, https://scan.coverity.com/projects/1038
winGRASS:
- install https://icl.cs.utk.edu/lapack-for-windows/ or https://www.scipy.org/scipylib/building/windows.html#blas-lapack-and-atlas
Web CMS:
- discuss CMS migration to Wordpress
Vector network analysis
- Add turntable support for OSM data
