<br />areas will be assigned to the irrigated parcels. The well-to-parcel matching routine in StateDGI will then <br />be used to assign current active irrigation wells to the parcels. <br />89.16 Review, revision, and final classification of refresh results. Before conducting a formal <br />statistical accuracy assessment, a final round of focused QA/QC operations will be conducted on all <br />aspects of the irrigated parcel data (irrigated lands, crop types, ditch service areas, and well source) to <br />ensure data consistency and validity, and quality of line work. Maps will be printed displaying irrigated <br />parcels, crop types, service areas, and irrigation wells. To enhance the QA/QC process, meetings will be <br />held with each Water Commissioner in Division 1. Maps will be reviewed and notes made, and the <br />updated irrigated parcel data will be edited after the meetings as necessary. These meetings will <br />significantly enhance the refresh process by clarifying changes in the landscape since 2001. <br />89.17 Accuracy assessment. An assessment of the accuracy of classification of irrigation status and crop <br />type will be conducted using one-half of the field data collected and organized under Task 108.1. This <br />will quantify errors and determine classification accuracy for final reporting. <br />89.18 Summary memo of irrigated lands assessment. A number of detailed memos have been <br />prepared under SPDSS Phases 1, 2 and 3 that provide full and detailed technical descriptions of the data <br />and methods used in the SPDSS 2001 and historic irrigated lands assessment, as well as results and <br />accuracy assessments. The memos were produced under Tasks 89, 90, 91, 93, and 94. While these <br />documents provide a comprehensive description of the irrigated lands mapping process, they are lengthy <br />and detailed. There is demand and need for a summary of the most important elements of these memos as <br />a summary document. This document will target all users of SPDSS products including government <br />agencies, consultants, and the general public and will describe the data and procedures used in irrigated <br />lands mapping in a concise, informative, and visually attractive publication. This summary memo will <br />reference the individual memos for those interested in the details and will be a stand-alone document that <br />describes the approach, results, and conclusions of the entire irrigated lands. The summary memo will <br />include appropriate amount of figures, tables, and graphics. <br />Deliverables: <br />89.11 Reference data for 2005 SPDSS refresh in GIS (shapefile) format, supported by FGDC compliant <br />metadata. <br />89.12 through 89.16 Irrigated parcel boundaries in GIS shapefile format. Maps of irrigation service areas <br />and crop types for all districts covered in previous phases. Metadata for all GIS deliverables developed in <br />this task using FGDC compliant metadata format. Included in the metadata will be a description of <br />known data quality problems, a listing of steps involved in updating each irrigated parcel GIS shapefile. <br />A description of the QA/QC procedure will be included. <br />89.11 through 89.17 Technical memorandum describing the update of irrigated parcels, irrigated vs. non- <br />irrigated lands classification, crop-type classification, refresh of ditch service areas and well sources, and <br />results of the accuracy assessment. <br />89.18 Summary memo describing the 2001 and historic SPDSS irrigated lands assessment that is detailed <br />in deliverables from Tasks 89, 90, 91, 93 and 94. <br />Task 90. Statewide Landsat Imagery Acquisition and Processing <br />Objective: This task has two main objectives. The first is to create consistent image products for use in <br />irrigated lands mapping and other applications using a complete, statewide, multi-date Landsat image <br />archive for 2005 acquired in June 2006. The final Landsat data products will facilitate full generation and <br />update of statewide irrigated lands mapping. The second objective is to evaluate existing CDSS <br />operations for mapping irrigated lands via literature review and industry survey including a detailed <br />comparison of MODIS and Landsat capabilities and limitations for mapping irrigated lands. <br />
