Quit ARCANFO. <br />5. The user should have a mapset with a subdirectory called "arc" in GRASS. <br />6. Move files from the user workspace with extension .1 in, . pt s, and . txt to the created <br />subdirectory "arc" in the mapset. <br />7. Running GRASS, run the command "v. in. arc" <br />8. Running GRASS, run the commands "v. support" and "v. digit" to regenerate <br />topology and identify organization, name, scale, source, author, and other descriptions. <br />9. While running GRASS, run the command "v. to. rast" to export vector data to raster. <br />10. A raster file is created at the resolution of the input data from ARC/INFO. <br />After the data have been imported into GRASS, the routines for displaying information in GRASS <br />can be incorporated into the GUI so that a seamless interface occurs. The advantage of displaying the <br />spatial information using GRASS is that the source code is available and can be incorporated into the <br />program. <br />In this way, GRASS is used as a spatial display tool for the user to be able to display the spatial <br />information as well as provide a link to the other types of data (physical characteristics, time series, <br />structures, etc.) in INFORMIX. These types of queries can be handled directly by using ESQL <br />statements inside C program. The consumptive use modeling effort will make use of the GIS to <br />determine consumptive use for different regions as well as to provide irrigated acreage areas to the <br />model. The Visual Data Browser will allow the user to access information in the CRDSS Database by <br />site maps displayed via GRASS. <br />A275 05.01.95 a 1.06 -2 CSU IDS <br />
