Evaluation System on Aggregate Resources Potentiality using GIS

Abstract

Geographic Information System (GIS) is widely used to input, store, retrieve, manipulate, analyze and present geographically referenced data. We adapted it in order to evaluate the aggregate resources potentiality.
By using GIS, aggregate resources database was constructed from the five information groups: geology, geographical features, development regulation zone, environment and economic value. These sub-systems were combined organically to search locations satisfying certain conditions for development of aggregate resources. Three kinds of raster data of 1 km meshes were produced from the database on rock distribution stage, development regulation zone and an area where economical development was possible. A combination of these data is enable to calculate the acceptable amount of resources. Minable meshes were extracted from the map by applying the map operation function of GIS to the three kinds of classified raster data.
