The individual programs funding the research cover <br />3318 the survey costs of these trips, <br />3319 . Complete a high precision Control Network for spatial-positioning of research sites <br />3320 in the river corridor and geo-referencing topographic, hydrographic, and remotely <br />3321 sensed data such as multispectral, hyperspectral, aerial photography. To date there <br />3322 is continuous control from Glen Canyon dam to the end of GIS area 5. It is <br />3323 necessary that this control be established to achieve the objectives outlined in the <br />3324 Physical Resource Program. <br />3325 . Ground truthing, geo-referencing, and image rectification of remotely sensed data. <br />3326 . Hydrographic channel map of all GIS sites and between GIS sites as needs dictate <br />3327 and control is established in support of the Physical Resource Program sediment and <br />3328 flow modeling. <br />3329 . Continue development of terrestria1 ground topography maps. Terrestria1 ground <br />3330 mapping in the Canyon is difficult and expensive, Technologies are currently being <br />3331 evaluated for achieving this objective as part of the Remote sensing initiative. The <br />3332 GCMRC will use only the most cost effective method which conforms to National <br />3333 Mapping Standards accuracy. Accurate terrestrial ground topography maps are <br />3334 essentia1 for the sediment and hydrology model development being proposed by the <br />3335 Physical Resource Program. <br />3336 . Continue to develop a survey database for easy access and a seamless GIS interface. <br />3337 Development of archival protocols for GISlDatabase interface for control, mapping <br />3338 products, and metadata <br />3339 . Research and implement any current or developing management objectives in the <br />3340 execution of sound survey practices and procedures <br />3341 Survey support of research activities funded by the GCMRC largely consist of trained <br />3342 GCMRC surveyers, assistants, and professional volunteers accompanying scientists in the <br /> <br />November S, 1998 <br />Second Draft - Do Not Cite, Pbotocopy, or DistrIbute <br />
