Raster modules

  • r.colors.out: new
  • r.external.out: new
  • r.cost faster by orders of magnitude (10x - 100x)
  • r.walk faster by orders of magnitude (10x - 1000x)

  • r.watershed improved from G6.3 to G6.4 to G6.5 to G7: faster, less memory, floating point DEM support, MFD, clean stream extraction from MFD, segmented mode in G7 faster than in G6 by orders of magnitude (segmented mode in G7 only a bit slower than all-in-ram mode of G6.4)
  • r.gwflow/r3.gwflow: Groundwater flow module update
  • Large File Support (LFS) globally enabled

Vector modules

  • v.krige: new
  • v.in.ogr faster for polygon-import, cleaner output

Libccmath

  • new library for numerical functions

Libdbmi

  • Added support for OFTDate, OFTTime, OFTDateTime

Libgis

  • WPS support implemented in parser
  • Libraster separated out into own library
  • Store metadata in $HOME/.grass7 directory

Libgmath

  • gmath solver updated to use ATLAS blas level 1 algorithms.

Libraster

  • Libraster separated out from libgis, refactored

Libvector

  • Large File Support (LFS) added
  • new spatial index, and spatial index kept in file: faster queries (>10x for large vectors), less memory for opening an existing vector
  • cleaning functions 'break polygons' and 'snap lines' faster, less memory
  • Simple Features API/OGR read/write support (ongoing)

Documentation

  • Use Python to generate HTML docs

API

Portability

  • All shell scripts have been rewritten in Python
  • MS-Windows portability improved, new spawn functions (backported to 6.5 and 6.4)
  • MacOSX portability improved

  • g.ask, g.setproj
  • i.class, i.ortho.photo, i.points, i.vpoints (need to be ported; old display architecture decommissioned)
  • raster:
    • r.average, r.bilinear, r.median (merged into ...)
    • r.digit (need to be ported; old display architecture decommissioned)
    • r.le.patch, r.le.pixel, r.le.setup, r.le.trace: replaced by r.li.*
