<br />. <br /> <br />. <br /> <br />89.2 A technical memorandum describing the entire land classification process including satellite <br />imagery and other data, image processing and classification. The ground truth data will be <br />described and an accuracy assessment will be prepared including assessment tables and error <br />matrices for reporting the classification accuracy. <br /> <br />89.3 The following data and information generated under various subtasks of Task 89 will be <br />provided for the South Platte and North Platte River basins. Final products for Districts 1,2, <br />3 and 64 wi II be produced and draft products will be produced for other districts, to be <br />finalized during Phase 3. <br /> <br />Plots <br /> <br />1. lnigated field polygons <br />2. Ground truth plots <br />3. Crop types for irrigated lands <br />4. Draft maps containing review notes from water commissioners, districts <br />and/or water users <br /> <br />Raster Files <br /> <br />1. Classification of irrigated lands and crop type in raster format <br />2. Interim files for verification of results, such as Feature Space, Tassel Cap and <br />Threshold (or distance). <br /> <br />Arc Themes/Coverages <br />1. lnigated field polygons <br />2. Ground truth plot locations and attributes <br />3. Crop type for irrigated fields <br /> <br />Other Files <br /> <br />1. Signature Separability (array form) <br />2. Signature File (Final - .sig) <br />3. Signature File (every class- before merge add/delete/etc functions) <br /> <br />89.4 Metadata will be developed for all GIS deliverables developed in this task using Federal <br />Geographic Data Committee (FGDC) compliant metadata format. Included in the metadata <br />will be a description of known data quality problems and a listing of steps involved in <br />developing each GIS coverage and modifications for inclusion in the SPDSS. Also, a <br />description of the QNQC procedure will be included along with the persons reviewing the <br />information and the contact of the person responsible for the final review and approval of the <br />product. <br /> <br />Task 90 -Image Base Map and Irrigated Field Boundaries <br /> <br />Objective: <br /> <br />Develop a digital, seamless image base map for the entire South Platte and North Platte River <br />basins. Delineate field boundaries for all irrigated parcels. <br /> <br />Page 4 of 26 Pages <br />
