GRASS 7 ideas collection

Raster

Library

• Rewrite library from scratch

Modules

• Remove r.in.arc and r.out.arc, if a related bug in r.in.gdal is fixed. The integer/floating point detection for AAIGrid driver in GDAL was fixed after 1.3.2 release, so r.in.gdal and r.out.gdal should be enough now.

• Remove the code from r.info that makes it print projection information - we have g.region and g.proj for that. Moreover, r.info always prints a bogus (zone 0) information in non-UTM locations, which is confussing. See a bug report.

• fix the raster map history management (truncating long history, odd storage). It should work like for vector maps in GRASS 6.

Vector

Modules

• Remove doubled units in v.to.db GUI

• Fix the Column 'cat_' already exists (duplicate name) in v.in.ogr. Maybe by creating columns cat_1, cat_2 etc. each time a Grass vector is exported to shapefile and imported back to Grass?

General

Modules

• g.remove, g.mremove, g.rename, g.copy: don't allow for default datatype (which is currently raster) [1].

Imagery

Library

Do merge of image libraries:

• A)
  • lib/imagery/: standard lib, in use (i.* except for i.points3, i.rectify3)
  • imagery/i.ortho.photo/libes/: standard lib, in use (i.ortho.photo, photo.*)
• B)
  • lib/image3/: never finished improvement which integrated the standard lib and the ortho lib. Seems to provide also ortho rectification for satellite data (i.points3, i.rectify3)

Modules

• merge of i.points, i.vpoints, i.points3
• merge of i.rectify and i.rectify3
• addition of new resampling algorithms such as bilinear, cubic convolution (take from r.proj?)
• add other warping methods (maybe thin splines from GDAL?)
• implement/finish linewise ortho-rectification of satellite data

Data management

• store vertical units on per-map base, using code from units software
• store vertical map datum on per-location base (GDAL/OGR needs the same enhancement)

GUI

• Multiplatform
• Fast
• Small on monitor
• Number of window reduction
• Managable from command line via d.* modules (which will have to be rewritten too)

• Python?
• WxWidgets?
