GRASS Wish List

[Ronald Thomas]

Adding to Craig's (caa at noaacrd.colorado.edu) list;

A version of v.cutter that simply uses the current REGION as the
'cutting' template: sort of a "v.resample".

     A vector/raster coincidence tool, or a vector line/polygon
coincidence tool; that would report the distance (length) of a
vector through a polygon/area, giving individual segments and an
accumulative total.  Also, a tool that would measure length of a vector
over elevation gains & losses, giving a TRUE(r) distance reading.

     A /dig_hist directory and associated files, accessible
through v.support, which carry the history of a vector map on to
the /hist directory when rasterized, and "cats" the history of 2
or more files when they are "patched" or otherwise combined in
vector or raster format.  A list of procedures performed, such a
"reclass of XXXXX" or "created by v.patch" would be attached to
the history in addition to being sent to the TITLE field. 

     A beefed up rewrite of the SCS contributed program,
v.report, that fixes peculiarities of the current program; in
particular, its reliance on a sequential  category file (currently, no
breaks in assigned attribute #'s allowed), and its faulty 'perimeter'
function.

     An improvement to i.composite that allows it to assign
colors to the range of histogram values of a TM band, rather than
the actual values (an adaption of i.grey.scale?).  ERDAS features
this, and it produces cleaner visuals of imagery.
