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:

Core:

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

QA:

winGRASS:

Web CMS:
