<br />. <br /> <br />C\ <br /> <br />C), <br /> <br />~ <br /> <br />. <br /> <br />. <br /> <br />Utah <br /> <br />The state of Utah is currently conducting a mapping project to <br />identify field boundaries and cropping information throughout the state. <br />As QA/QC is completed, the data are forwarded to 0-3744. The Utah data <br />are provided in ARC/INFO format and are 100% field checked. Due to the <br />level of verification, satellite image interpretation will not be required for <br />Utah. This will result in a cost savings of $37,485 ($6247.50 * 6 TM full <br />scenes) on data alone. <br /> <br />New Mexico <br /> <br />The irrigated portion of the San Juan Basin is covered by some 50 <br />USGS 1:24,000 quads. Color infrared photographs of the area are available <br />from the USGS for 1988. Upon arrival of the photos, interpretation and <br />ARC/INFO coverage development should require 6 to 8 weeks. Presently, it <br />is not clear whether the state will assist Reclamation with the QA/QC of the <br />photo interpretation and crop typing. <br /> <br />As part of another project, 0-3744 has acquired complete TM <br />coverage (1992 images) for the state of New Mexico. Although the Colorado <br />images are from 1987, these 1992 images could be used at no additional <br />cost. <br /> <br />Wyoming <br /> <br />Vector data for the Upper Colorado portion of Wyoming currently <br />exists in digital form. The files have been converted to ARC/INFO format, <br />but need to be reprojected to Albers Equal Area to be compatible with data <br />for the rest of the project area. At this time, there is no .crop type <br />information tied to these fields. <br /> <br />FUTURE WORK <br /> <br />In January 1994, the Upper Colorado Irrigated Lands Project will be <br />re-evaluated to determine priorities for satellite image processing. <br />Scheduling will be based upon the availability of ARC/INFO field <br />boundaries, crop type information, and TM coverage. <br /> <br />13 <br />
