An integrated approach for development of hill areas using satellite and collateral data - A case study from India
Methodology
Using color, texture, pattern, association, size, shape & temporal behaviour; multidate TM images have been interpreted for forest, landuse, groundwater, geology, lienametn & wastelands of the area. Base map, slope map, drainage and watershed maps on 1:50,000 scale were prepared from the SOI topomaps. Slope maps was prepared based on methodology discussed in lan Galbraith (1983).
Using the above methodology seven classes of slope calculated viz.,
| Class |
Percent Slope Range |
| 1 |
0-2 |
| 2 |
2-8 |
| 3 |
8-16 |
| 4 |
16-35 |
| 5 |
35-50 |
| 6 |
50-85 |
| 7 |
85-100 |
Boundaries of these slope classes are based on work done by various authors Omakupt (1985), Wacharakitti (1985). Baharuddin (1985) etc. on observed relationship of various slope classes with different land use/land cover.
Ground check spread over 4-5 days has been carried out for each theme to verify interpretations, image interpreted maps were finalized based on the ground truth and collateral data/information. The information derived from imagery were transferred to the base map and final thematic maps were prepared.
Information on various resources, available from satellite data/maps and collateral information/data (from concerned agencies) were integrated and analysed to understand overall resources potential of the area. A suggested land use / land cover map of the area was prepared following land use classification scheme by NRSA, 1989. based on the above analysis scientific development plan of the area was suggested based on existing land use, water availability (Surface/ground/rain water), wastelands, land capability, slope and topography etc.
