New modules and scripts in GRASS 4.2.1 (22. Sept. 1998) Beside the focus on bugfixing more than new modules and scripts were applied to the GRASS package. The database management is still unchanged! So there is still no floating point management in raster files, it is coming soon with the release of GRASS 5.0 in summer 1998. New modules and scripts in 4.2.1: display/d.area # display vector polygons colorized display/d.barscale # displays a barscale (position with mouse) display/d.myzoom # nice zoom module display/d.pan # panning module display/d.rast.leg # displays a raster map and its legend on GRASS mon. display/d.rgbcolortbl # displays color table display/d.param.scale # belongs to r.param.scale display/d.site.labels # displays site labels display/d.vect.zoom # vector zoom display/d.what.sites # query sites paint/p.vrml # output of VRML 1.0 code ps.map/scripts/ps.map.barscale # create a barscale vector layer for ps.map raster/r.affinity # analysis classifier based on affinity index of David W. Goodall raster/r.agnps50 # successor of r.agnps (AGNPS 5.0 now) raster/r.clump1 raster/r.distance # calculates distances between objects raster/r.feat.thin # used for r.param.scale raster/r.in.bin # import binary files into GRASS raster/r.in.gif # 8 bit GIF import (GIF 87) raster/r.in.ppm # 24bit PPM import raster/r.kappa # Kappa statistics raster/r.kineros # module for determaining stream networks raster/r.lags # calc. spatial dependence measure (Moran's I or texture) raster/r.moran # calculates Moran's I stats. for a raster surface raster/r.out.pov # height model output for POVRAY (Persistence of Vision Raytracer) raster/r.param.scale # calculates elevation parameters raster/r.statistics # univariate statistics raster/r.sunmask # calculates shadows in a DEM from sun raster/r.surf.fractal # creates a fractal surface of a given fractal dimension raster/r.surf.gauss # produces a raster map layer of gaussian deviation raster/r.surf.random # produces a raster map layer of uniform random deviates raster/r.tiff # 8 bit import, 8/24bit export (corrected SCS version) raster/r.to.sites # converts raster to sites raster/r.tribs # belongs to r.kineros raster/r.water.outlet.3.0 # calculate watersheds from given point raster/r.xy # can be used to produce functions in the form: z = fn(x,y) for r.mapcalc scripts/d.rast.leg # displays map and legend on raster window scripts/d.rast.rescale # displays on-the-fly-histogram stretched image on GRASS monitor scripts/i.oif # calculate Optimum Index Factor for LANDSAT TM band combinations scripts/i.spectral # displays with gnuplot satellite spectral response at user defined spot scripts/i.tasscap # Tasseled cap (Kauth Thomas) transform scripts/ps.add.pagesize # add new pagesize on ps.map products scripts/r.edge.dig # Digitize a vector line between two given raster values in a raster map scripts/r.in.arctiff # ARC/INFO TIFF import (with .tfw file) scripts/r.out.arctiff # ARC/INFO TIFF export (with .tfw file) scripts/r.out.bil # BIL export (for ARC/INFO, ARC/View etc.) scripts/r.reclass.area # reclass a raster map by specified area size scripts/r.regression.line # calculate linear regression from two raster files scripts/s.in.gps # read sites from GPS Text file scripts/s.out.gps # write sites to GPS Text file scripts/v.cutter.attr # polygon cutter with vector attributes scripts/v.out.gps # read vector sites from GPS Text file sites/s.buffer # generates vector buffer around a site point sites/s.geom and v.geom # successor of s.delaunay, s.voronoy sites/s.in.ascii.dem # import of DEMs with x y z values for conversion with s.to.rast sites/s.label # makes a paint-label file from a site list sites/s.nearest # calculates minimum distance from a site to another site sites/s.surf.bissf # bilinear surface interpolation sites/s.surf.krig # Surface interpolation from site data via kriging sites/s.sv # calculate semivariogram sites/s.windavg # Window average filter for sites vector/v.digspline # modified v.digit with spline interpolation vector/v.distance # Calculates a distance from a point to nearest line or point in vector layer vector/v.shape/* # ARCVIEW-SHAPE utilities vector/v.plant # inserts nodes in equidistance into vector map vector/v.what # Query the category contents of a (binary) vector at user-selected locations vector/v.surf.spline # interpolates surfaces from vectors with cubic splines NRCS/vector/v.in.atlas # ATLAS GIS interface NRCS/vector/v.in.dlg_atr NRCS/vector/v.out.atlas # ATLAS GIS interface NRCS/vector/v.out.mapinfo # MAPINFO GIS interface NRCS/vector/v.zoom # Zoom to user defined vector areas SCS/display/d.fix.ortho # allows coordinate moving of raster images through mouse TclTKGRASS (separate package) # graphical user interface for GRASS 4.x (4.1.x, 4.2.x) using Tcl/Tk8.0 Markus Neteler neteler@itc.it University of Hannover Germany
