Its purpose is to provide spatial analysis capabilities for trend detection to the <br />AMWG, GCMRC staff and the public and to maintain a library of GIS thematic coverages of <br />the study area. The GIS will be tightly integrated with the remote sensing initiative and, in <br />conjunction with image processing software. will be the primary analysis tools of remotely <br />sensed data sets. The GIS is an integral component of the monitoring program and base data <br />development is used to assess the impacts of variable flow rates within the Grand Canyon <br />(B.O.R. Report: R-95-14, Patrick J. Wright, et al.). It is an objective of the GIS program to <br />use geographically referenced base data to develop an integrated ecosystem-based <br />monitoring program (B.O.R. Report: R-93-20. Lee F. Werth, et al.). The GIS is also an <br />important analytical tool for integrating and comparing spatial data that has been collected in <br />the past and data that will be collected in the future. The digital elevation models stored <br />within the GIS and developed by the Survey Department will enable GCMRC to answer <br />question regarding flow rates, water surface elevation and percent inundation. The questions: <br />what is at..., where is it true that.... what has changed..., which data are related..., and what <br />happens if... along with many other TWG, AMWG. and staff questions concerning spatial <br />data, modeling and trend analysis can be answered with a GIS. <br />GCES had significant accomplishments in GIS system development and <br />establishment of meta-data protocols. GIS activities were concentrated along 17 reaches of <br />the Colorado River identified as GIS Sites 1-17 (Figure 5.2). Each GIS Site has up to 20 <br />thematic coverages associated with it depicting spatial relationships of physical. biological, <br /> <br />,. <br /> <br />> <br />i/ <br />.. <br />, <br />:~, <br />." <br /> <br />> <br /> <br />~> <br />-Ii <br /> <br />:<:C: <br />" <br /> <br />r ~. <br /> <br />;.,. <br />."i'..: <br /> <br />,. <br /> <br />:,:. <br />t.; <br />, . <br />;;~. <br /> <br />.~j. <br /> <br />:-:. <br />1l <br /> <br />..~ <br />:.a.~~~ <br />.'; ~ <br /> <br />November S, 1998 <br />SecoDd Draft - Do Not Cite, Pbotocopy, or DIstrIbute <br />
