v.support <main> GRASS Reference Manual <main> v.support <br /> NAME <br /> v.support - Creates GRASS support files for (binary) GRASS <br /> vector data. <br /> (GRASS Vector Program) <br /> SYNOPSIS <br /> v.support <br /> v.support help <br /> v.support [-spr] map=name [option=name] [threshold=value] <br /> DESCRIPTION <br /> v.support builds GRASS support files for (binary) GRASS <br /> vector data files. These support files supply topology <br /> (dig_plus) and category (dig_att) information that are <br /> needed by other GRASS programs (e.g., by v.digit, v.to.rast, <br /> etc.). <br /> The program gives the user the options of: (1) building <br /> topological information (the dig_plus file) needed by <br /> v.digit for the vector data file, and/or (2) editing the <br /> category label (dig_cats) file associated with the vector <br /> data file. <br /> OPTIONS <br /> Program parameters and flags have the following meanings. <br /> Flags: <br /> -s Snap nodes. Valid only with build option. <br /> -p Prompt user for threshold value. Valid <br /> only with build option. This flag is <br /> designed to be used only by the v.import <br /> program, and can usually be ignore. <br /> -r Reset corners of map region from range of <br /> data values. <br /> Parameters: <br /> map=name Name of binary GRASS vector data file for <br /> which support files are to be created or <br /> modified. This map layer must exist in <br /> the user's current GRASS mapset. <br /> option=name Build topology information (dig_plus <br /> file), or edit categories (dig_att file) <br /> for map. <br /> Options: build, edit <br /> Default: edit <br />Page 12 <br />01/03/97 2.03-02 - Lange <br />
