<br />MAY-31-94 TUE {5:47 <br /> <br />P,02 <br /> <br />1301216 <br /> <br />Task 1.(16. Spatial Databa$e <br /> <br />Introduction <br /> <br />1. Oblectlves <br /> <br />. To design and populate a spatial databa.c;e with the data types identified for Year <br />1 (anticipated data types and database population requirements are shown. in <br />Tables 1.06-1 and 1.06-2). Spatial database requirements are discussed in <br />Technical Memorandum 1.06-1. <br /> <br />. To develop a spatial data viewing tool that will allow the user 10 view gea- <br />referenced data in a grdphical representation using the GIS software GRASS. <br />1lte data will be presented in !he fonn of lIrea. maps (raster). line maps (vectors), <br />or locations (points). <br /> <br />. To develop a spatial database that will support the CRDSS prototype. The <br />spatial database will be populated, at the minimwn. for me Gwmison River <br />basin. <br /> <br />2. Assumotions <br /> <br />. The Geoloc table (see Appendix 8, CROSS Database Design) will be used to <br />link the spatial database to Lhe relational databa.c;e. <br /> <br />. The State will coordinate with Denver Water to obtain available spatial <br />information. <br /> <br />. The State will convert lIIl section, township. and range date to latitude and <br />longitude for locations mat need to be stored in the spatial database (e.g., <br />diversion structures), <br /> <br />. The spatial database construction and popullltion will utilize the GIS software <br />ARCIINFO. . <br /> <br />. The spatial database viewing and modeling tools will utilize the OlS software <br />GRASS, <br /> <br />. Development worlt In Year 1 will focus on the Gunnison River basin, This will <br />allow the detennination of the extent and quality of data availnble for each of the <br />required layers. <br /> <br />.m ..,." 2-17 <br />
