This support may be in the form of precise measurement of <br />3271 geographic coordinates of a sample collected in the Canyon or in the generation of <br />3272 topographic maps used for erosion monitoring of terraces adjacent to the Colorado river. <br />3273 The Survey department is also respoosible for establishing and maintaining accurate <br />3274 geographic control in the Canyon that is essentiaI for accurate geo-referencing of remotely <br />3275 sensed data and spatial analysis of resource data using modem image processing and GIS <br />3276 technologies. These technologies are critical to the integration and analysis of the diverse <br />3277 scientific data that have been collected in the Canyon over the past 15 years. Products of <br />3278 the Survey department include precise sample location coordinates, topographic maps, river <br />3279 channel maps and cross sections, digital elevation models, and digital terrain models. This <br />3280 information provides the basis for spatial analysis of data within the ecosystem using GIS <br />3281 software that in turn provides area and volumetric change detection capabilities of <br />3282 resources. <br />3283 The Survey department was initiated in 1990 when GeES began the development of <br />3284 the GIS sites (Figure 5.2), it became necessary to establish topographic control for these <br />3285 sites as well as all other research related mapping in the Grand Canyon. The development <br />3286 of sound topographic and mapping control required good survey control to build these <br />3287 spatial data sets. However, as a result of extremely difficult logistics and access to the <br /> <br />November 5, 1998 <br />Second Draft - Do Not Cite, Photocopy, or DIstrIbute <br />
