15-20 February 2016


Community stuff:

Time-based task:

  • Wed morning - GIS.lab (Markus, Luca, Ludka, Martin, ...)
  • Fri morning - OSM data -> Vector network analysis with turntable (Markus, Luca, Stepan, ...)


  • 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 Hence ZLIB may qualify for the default NULL compression algorithm.



  • Kickstart of GRASS with LatLong predefined, open import wizard | switch projection



Web CMS:

  • discuss CMS migration to Wordpress
