Task 89 - Mapping Of Current Land Use And Irrigated Field Boundaries

Objective:

Current land use--including irrigated areas and major crop types-will be mapped using multiple
satellite images from the 2000 season and applicable GIS data. Also, general classes of natural
vegetation will be mapped for the groundwater modeling areas.

Background:

Current land use will be mapped in draft for the entire study area during Phase 1 and 2. Review,
revision and final map products will be provided for Districts 64, I, 2 and 3 during Phase 1 and
2, and completed for the remaining districts during Phase 3.

Approach:

89.1 Finalize Methods And Order Imagery. Assess the quality and availability of
multispectral, 30m resolution Landsat satellite imagery for use in this task and prepare a list
of recommended satellite data for acquisition. Collect and review literature and reports of
researchers and previous State contractors engaged in mapping land use and crop types for
