70 2.3 Resources Data Bases - Spatial Consistent with the watershed level planning requirement, thematic maps are generated using IRS data. Both the digital and visual techniques are followed interactively. Special techniques of stratification, layered approach and composition, aggregation, refinements are adopted wherever necessary to improve the quality of mapping. The primary thematic maps generated are Land use/Land cover, Soil, Geology, Geomorphology, Digital elevation, Drainage & Watershed boundaries, Transport network and village boundaries. The details are provided in Table 1. Table 1. Theme Map Source Remarks Landuse/ land cover (Multi date) IRS LISS-11 & III ground truth Digital classification using stratified approach, refinement using human logic Soil IRS L1SS-I1 & III & available maps, profiling Digital enhancements and visual interpre tation.

They are derived, in some cases, by direct translation of single thematic map and in others by combination of two or more thematic maps or chosen parameters of the different themes. These are Slope, Land capability, Land irrigability, Ground water potential, Run-off potential, Run-off depth, Peak run-off rate, Peak run-off volume etc. The details are provided in Table 2.

Voluminous information on these aspects exists at various sources and different levels are collated and quantified. These are Demographic, Input Status, Facilities, Sociologic, Financial, Policies & Priorities and Complementary data such as Agronomy, Forest, Industrial and Achievements and ongoing activities.
