Digital Map of The Distribution of Metals In Iraq Using Geographic Information System Techniques


The ability of geographic information systems in preparing of geo data base and its represented as digital maps is verified through data processing of mineral materials. This research aims to product digital maps for mineral materials in Iraq by transferring paper map(geological map) with scale (1:1000000) into digital map using scanning process and adjusting of coordinates system for this map using dereferencing process. Then layers are extracted from this map using digitizing process, these layers represented , also the ratio of these materials are represented on these layers as circle sector. The purpose of geo database is to make the features in geographic information system datasets and define a relationship among features that were displayed on maps as layers, each layer represents particular type of features which have been used for spatial analysis.
