0017S8 45 2. The Library has also implemented a consist.~nt peer review process to help ensure the quality of scientific projects conducted by the GCMRC. The Peer Review Protocols developed and administered by the library are utilized in the NPS permitting process for external review of project proposals prior to submittal to the NPS Research Office for review and approval. Survey Operations - The long term monitoring objectives of GCMRC require positions and elevations for past, present, and future spatial datas:ets. The GCMRC Survey Department's mission is to provide survey support for 1) collection of these spatial measurements and, 2) referencing the spatial data collected in the Colorado River ecosystem to the primary control network. The survey department is also responsible for establishing and maintaining the geodetic control network in Grand Canyon. The geodetic control network serves as the foundation for all spatial measurements necessary for long term monitoring. This control network also serves as the spatial framework for the Geographic Information System (GIS). The referencing of spatial data must be consistent in order to perform accurate change detection. All measurements collected for studies approved by the Adaptive Management Program are archived for quality assurance, quality control, network adjustment, and database integration. The survey department provides network control point coordinates and error estimates, QA/QC for remote sensing, topographic and hydrographic maps, and the additional manpower necessary to collect these data. The survey department staff also incorporates historical datasets that had been previously referenced to superceded or local control coordinates into the CRE database. This integration requires translation and rotation of the instrument and reference azimuth stations to match the most current coordinates, which reference the primary geodetic control network. The survey department is familiar with data collection and processing of topographic, hydrographic, and geodetic data. Specific equipment available to researchers includes static, kinematic, and Real Time Kinematic (RTK) Global Positioning Systems, single-beam and multi- beam hydrography, acoustic Doppler sensors, laser scanners and conventional survey equipment. The Survey coordinator assesses the level of survey support required to efficiently implement individual studies and evaluates and schedules equipment and personnel requests. Technical Support Coordination - Integration of support capabilities in the areas of GIS and Remote Sensing is critical to the success of scientific data collection and integration for all GCMRC FY2006 Annual Work Plan (Draft February 15,2005)
