changed from a Sun SPARCstation running Sun OS 4.1.1 to a SGI Indy running IRIX 5.2, some <br />porting issues needed to be resolved. The memory allocation and manipulation functions <br />needed to be updated, and some issues regarding the change from X11R4 to X11R5 were <br />solved. <br /> <br /> Modifications were made to evapotranspiration maps to make them compatible with CRDSS. <br />? <br />Some features were removed, fixed, or added in this process. <br />Subtask 5: Quality Control for Data Population <br />While incorporating data into ARC/INFO and GRASS from different formats of acquired data, <br />? <br />data quality has been checked. These quality checks include overlaying the display of geo- <br />referenced spatial data, such as county boundaries versus stream junctions, versus dam <br />locations, versus city locations, versus diversion structure locations, versus contour lines, from <br />elevation data and so on. <br /> <br />Vector coverages were imported from ARC/INFO into GRASS and overlaid on a raster <br />? <br />coverage generated with a predefined grid size (e.g. 50m X 50m). On regional coverages, such <br />as State and county boundaries, soil, land use, and hydrologic units, an error of less than 0.1 <br />percent was measured. On the irrigated acreage coverage where the range of size for parcels <br />goes below 2 acres, a grid size of 10m X 10m was generated to provide an error of less than <br />0.15 percent. Both of these seemed to be within acceptable limits. <br />Subtask 6: Visual Data Browser Tool <br />The overall design of the VDB interface was completed and implemented. <br />? <br /> <br />The VDB interface was incorporated into the CRDSS script and installed on the State's machine. <br />? <br /> <br />Continual enhancements to the VDB interface included fixing bugs, displaying multi- <br />? <br />maps, setting app-default files, setting environment variables, manipulating color maps, <br />helping through the Mosaic interface, and writing man pages. <br /> <br />The Visual Data Browser Reference Guide was developed and is available in the Mosaic <br />? <br />on-line documentation. It went through at least three distinct revisions. <br />Subtask 7: Develop DMI Software <br />The specific types of data needed by the consumptive use model were identified. This work <br />? <br />included identifying low-level DMIs needed to retrieve information from the database. <br /> <br />Task Memoranda 1.14-10 through 1.14-13 were written to describe low-level DMIs needed to <br />? <br />retrieve information from the database. <br />Subtask 8: Produce Hard-Copy Maps <br />IDS has purchased a Hewlett-Packard (HP) plotter used for printing the CRDSS hard-copy <br />? <br />maps. <br /> <br />3 <br />A 275 01.08.95 1.06-4 Lange <br />
