2.2 Task 2 Final specification of data and ordering <br />Objective: <br />To confirm the final selection and acquire the imagery required for a 2003 irrigated lands update <br />in the Lower Arkansas River Basin. <br />Methods: <br />Landsat Imagery <br />- Final specification of Landsat data from USGS <br />For the 2003 irrigation season, specify the date, cost, and I.D. of Landsat scenes that <br />provide the best discrimination of crop types or groups of crops with similar consumptive <br />use. <br />- Order recommended Landsat data from USGS <br />Digital Ortho Quads (DOQQs) <br />- Final specification of required DOQQs in Crowley, Otero, Bent Counties (1998 - 2001) <br />- Prepare order for DOQQs in Crowley, Otero, Bent Counties (1998 - 2001) <br />- Coordinate and order the production of updated DOQQs in Prowers County (1998) under <br />cooperative agreement with USGS. <br />Deliverables: <br />• Technical memorandum describing methods and products <br />• CDs with raw Landsat imagery <br />• CD or DVDs with raw DOQQ in tiff format <br />2.3 Task 2 Create a seamless digital orthoimage base map in compressed (MrSid) format <br />Objective: <br />Produce a mosaic of all available and recently acquired DOQQ in the Lower Arkansas River Basin into a <br />seamless digital orthoimage base map in compressed MrSid format. This task will be performed in two <br />phases. In phase 1, a mosaic will be produced for the western part of the basin with the currently available <br />DOQQs. In phase 2, another mosaic will be produced for the eastern part of the basin as soon as the <br />updated DOQQs in Prowers County become available from USGS (Task 2.1). <br />Methods: <br />• Collect available data from the State <br />• Manage and coordinate data production <br />• QA/QC of deliverable <br />Deliverables: <br />• Technical memorandum describing methods and products <br />• DVD with the seamless orthoimage in MrSid format <br />Page 2 of 4 <br />
