<br />. <br /> <br />. <br /> <br />, <br />. <br /> <br />information from the DOQQ's. The contractor will use the 30-meter LandSat TM imagery as an <br />extra visual check to verify field boundaries and to quickly identify new fields that may be <br />outside the 1993 data. Two items will be added to the PAT table, Crop_Type and Irrigation <br />Status. <br /> <br />Work Product: <br />Quad sized coverage's ready for internal QC. <br /> <br />Task 4 - TGS Internal Quality Control <br /> <br />When each USGS Quad24 sized coverage is completed, topology will be built using the <br />Arclnfo build command and all coverage parameters will be verified using the & describe <br />directive and the Dog Creek QAlQC software. Contractor will quality control each quad sized <br />coverage on-screen before plotting the hard copy plots. <br /> <br />Work Product: <br />Quality Controlled coverage's ready to be plotted to check plots. <br /> <br />SSI Data Review <br /> <br />SSI will periodically review hard copy plots for the accuracy of field polygon capture before <br />being sent to the State <br /> <br />Task 5 - Plot Quads for DWR field boundaries/crop typing <br /> <br />The hard copy plots for DWR QC will be created using an automated AML routine running in <br />ArcPlot. The plots will show the field boundaries as interpreted from the DOQQ's and Landsat <br />TM imagery. The USGS DRG's will be plotted in the background and the unshaded field <br />polygons will be drawn over top. Each polygon will be plotted with a unique polygon id as a <br />text item at the centroid of each polygon. Division Engineer's will be delivered plots every <br />week to be used by their water commissioners. The water commissioners will compare their <br />field notes and maps to the field boundaries created from the DOQQ's. The water <br />commissioners will make red line edits and explanatory annotation on the plots to show where <br />field boundaries or other features have changed as well as identifying crop types if known. The <br />contractor needs timely and accurate review and revision of the check plots for the correct <br />configuration of field boundaries, the status of irrigation and the crop type in the fields. To <br />facilitate this task the contractor will develop a document to provide step-by-step instructions to <br />the water commissioner's. The contractor will also meet with each commissioner and staff to <br />provide training and offer start-up support. <br /> <br />Deliverable to State: <br />Check plots of each Quad sized coverage showing 2000 Irrigated Acreage field <br />polygons drawn over the DRG's of that area will be delivered to the Division <br />Engineer's for their QC and comments regarding crop type and irrigated status. <br /> <br />Page 15 <br />
