Digitizing the Forest Resource Map Using ArcGIS
The major challenges we face in the real world today is overpopulation, pollution, deforestation, natural disasters which have a critical geographic dimension and also have a geographical component. Geographical Decision Support System (Geo-DSS) is a demanding field, since enormous amount of spatial data have been collected in various applications, ranging form Remote Sensing to GIS, Computer Cartography, Environmental Assessment and Planning. Although some efforts were made to combine spatial mining with Spatial Decision Support System but mostly researchers are using a spatial database for popular data mining approach. GIS will give you the power to create maps, integrate information, visualize scenarios, solve complicated problems, present powerful ideas, and develop effective solutions like never before so that it supports strategic decision making. With GIS application we can open digital maps on computer, create new spatial information to add to a map, create printed maps customized to our needs and perform spatial analysis on it. There is a great deal of geographic data available in formats that can not be immediately integrated with other GIS data. In order to use these types of data in GIS it is necessary to align it with existing geographically referenced data. This process is also called georeferencing. Georeferencing is a necessary step in the digitizing process. Digitizing in GIS is the process of “tracing”, in a geographically correct way, information from images/maps. In this paper the processing of digitizing the forest map and the converting the georeferenced map into attribute data is depicted which can be further used to construct spatial database and on which spatial analysis can be performed.
