The following is a list of known contributions to GRASS 4.2, work in progress,
or freely available programs related to GRASS. The list is current as of
10/15/93. The cutoff date for acceptance of contributed code to be included
in GRASS 4.2, as well as a release date, will be established in November.
There are additional programs not included here, pending verification with
the author. Please report any additions or changes to Nancy Taaffe, email
taaffe@zorro.cecer.army.mil.
v.circle Creates a vector file of circles which uses a "site_lists" file
as center points of those circles
r.in.elas Copies and converts as ELAS raster file to GRASS cell file
r.out.elas Copies and converts a GRASS cell file to an ELAS raster file
r.le Programs for calculating traditional measures of landscape
structure
r.water.fea GRASS integrated finite element, kinematic wave
hydrologic model
Xgrasteredit X-based GRASS raster editor
progman Interactive programmer's manual
GUI (oo) Object oriented graphical user interface for GRASS
d.legendbar Displays a legend bar for a raster map layer in the active
frame on the graphics monitor
r.setcats Set-up category text for a raster map layer by automatic
label generation, or by assigning a category text string
to each category value in the map
s.filter Create a new site-list by filtering an existing site-list
s.in.table Convert a table of specially formatted site information into
one or more GRASS site-lists
s.to.labels Creates annotation for a GRASS site-list, by creating a paint
labels file
v.filter Creates a new vector map by copying specified vectors from an
existing vector map
r.colors Modified for color.eq (histogram-equalized blue-green-
yellow-red wave)
Mapbrowse GUI designed to allow user to browse through maps in the
GRASS database. Build map displays made up of raster maps,
vector maps, site symbols and label text. Then save display
to file, print, or convert to GRASS display script.
v.in.sdts SDTS to GRASS import program
v.out.sdts GRASS to SDTS export program
r.flow flowtracing program based on vector grid approach
s.kcv Randomly partitions sites for k-fold validation
s.univar Simple univariate statistics
s.rand Generate random sites
s.semivar Exploratory analysis and semivariogram modeling
g.gnuplot GRASS terminal for GNUPLOT
s.to.rast Provides command line option to interactive s.menu task
d.vect.lu Displays line-vector maps in different colors, depending
on the attached attribute. Great for large maps with
many categories.
r.sun Computes insolation-related parameters
r.hydro GRASS integrated finite difference, diffusive wave,
two dimensional hydrologic model
r.meta Collection routine for metadata
s.surf.tps Numerous enhancements have been made
r.surf.tps Resampling and smoothing raster files
s.surf.tps.ll Version for lat-lon
GRASS/Genamap GRASS Genamap integration
r.variance Computes variance in one data layer over regions defined
in another layer
r.composition Computes areal percentage of all classes in one data layer
over regions defined in another data layer. Output is a
text file that may be read from another program.
m.dted.examine Modified for lat-lon
m.dted.extract Modified for lat-lon
r.in.ll Modified for lat-lon
