: -- MS 26 Oct 2007: It was, until there was a "one row-off" bug in "g.region vect= res= -a". Fixed by Glynn in last days. A remaining issue, less important, is that "g.region vect= res= -a" needs to be run twice if the initial and target region resolution differ. This is not normal nor desired, but Glynn says it's been this way for years now. I confirm it applies to 6.2 at least too. A must-fix for GRASS 7, probably not to be fixed for legacy reasons in 6.2, and to be decided in regard to 6.3. As to me, I'm for fixing it in 6.3.

** allow multiple maps to be selected. This would directly address Eric's question. If the output is a map, it would be the equivalent of v.patch on all queried vector elements.
** add operators "contains" and "adjacent". Contains=all vector features whose nodes are completely inside a polygon (or inside or touching the boundary). Adjacent=all vector features who share a node/point or line/boundary with the selecting feature. Because GRASS is topologically correct, adjacency information is readily available.<BR>--HB: op="not" too please.
** maybe change option names from ainput and binput to selector and selected or queried. This would have to wait until GRASS 7, of course. I find ainput and binput not very clear where used in other vector operations either (maybe I'm just dense).
: --HB: input order counts, so named map options have a function.
 
* v.what (query using coordinates):
** add flags -p and -g for current behavior (-pg could be the default if we wanted to do this before GRASS 7)
** add "output=" option to allow v.what to create a new map from the results of its query, like v.select does
** allow multiple maps for input, as with the suggestion for v.select
** allow coordinates to be read optionally as a line or area boundary (-l or -a?) instead of only as individual points.
** add operators overlap, contains, adjacent.(This also would make possible interactive vector selection with a mouse drawn box or polygon from the GUI)
 
*In other words, have v.select and v.what work the same except that v.select uses a vector map for querying and v.what uses a set of coordinate points.
 
* v.overlay (boolean combination of maps):
** drop the ainput and binput. Replace with just input.<BR>--HB: careful, order of maps can matter.
** allow multiple maps to be entered into input, not just 2
** deprecate v.patch because v.overlay with the OR operator replaces it. (If we wanted to do this before GRASS 7, we'd have to create a new module, maybe named v.combine or something like that because this changes the default behavior of v.overlay).
: --HB: does it completely? I could be totally wrong, but my thought was that v.patch is very fast and does not attempt to clean (overlay) features, just lump them together in the file. Certainly for most tasks v.overlay should be the suggested route in the documentation.

Move to Trac and note that it is histirical page. Link GRASS 7 or some general one.

The info here is really old. See the Trac development wiki and roadmap for the latest information.

GRASS 6.3.x feature plan

About feature plan

To make GRASS releases more often and more predictable, here is GRASS next releases feature plan. This feature plan has to be filled by developers working on GRASS 6.3.

TODO GRASS 6.3.0

There is the release branch for 6.3.x, see details at tags and branches. A release branch is considered as "frozen", only bugfixes can be done.

RC1

released 24 Oct 2007

RC2

Released 20 Nov 2007

RC3

released 30 Nov 2007

RC4

released 9 Jan 2008

RC5

released 19 Feb 2008

RC6

released 21 Mar 2008

6.3.0 final

  • released 23 Apr 2008
Must do
test:
  • [✓] r.out.gdal NoData
  • [✓] d.vect render=c
  • [✓] gis.m about->system
fix:
  • Trac milestone status
  • Any open bugs which are blockers for 6.3.0 should be flagged as such in the bug report.
  • Look over old Gforge and RT bug trackers. Refile in trac as blockers if they are release-critical and close old reports with a link to the new one. Copy over all past discussion so it has context and history.


tasks:
  • Change .grc extension for WxGUI as incompatible with Tcl/Tk .grc files.
trac #77
  • Update release announcement and press release blurb in Web-SVN: [1] (preview)
AND/OR http://trac.osgeo.org/grass/wiki/Release/6.3.0RC5-News
--HB, 4 March 2008: IMO Final 6.3.0 announcement should be posted on the website. It's cleaner. Trac Wiki is fine for the RC announcements and working on the annoucement but it seems to me tp host the final release announcement there is like greeting your new customers in the corner of your workshop, it's unprofessional.

-- HB 24 Oct 2007: waiting for a real world example of when this would be useful.
  • use GEM for GRASS Addons SVN - status unclear
    • gis.m menu part of this done (Michael)
