This document summarizes the development of a WebGIS system to identify potential areas for highland vegetable farming in Cianjur, West Java. The WebGIS uses spatial data layers like rivers, roads, markets, elevation, land use, and soils to apply criteria for suitable farming areas. These criteria include being within 100m of rivers, 1km of roads, and 5km of markets; having elevations over 500m; and consisting of shrubland, grassland, or other remaining land uses. The WebGIS analyzes this spatial data using tools like buffering, intersection, and merging to identify 46.7 square km of potential farming area, which is 1.2% of Cianjur's total area

Criteria
Criteria for shrimp culture:
1. To anticipate drought requires a location that maximum 100 m close
to the river
2. To decrease damage of agricultural product and for easy distribution
require a location that maximum 1 km close to the road
3. Site should be located within 5 km distance from the market
4. Preferred site should be on remaining area like shrub and open
area.
5. Have elevation higher than 500 m above sea level surface
6. Have fertile soil
