Preparation of Drainage Map using Geo informatics

Abstract

Remote sensing Technology is influences to lesad the everyday life of human beings, ranging from to study the weather changes and Resources management. This attempt deals with the use of Geospatial Technology for preparation of drainage nets work mapping of Vamsadhara River Basin to study the drainage characteristics. The geo coded Remote sensing Satellite data and toposheets collected from Survey of India to conduct primary study. Visual Interpretation technique has been applied and field work also done to gathered the data from different departments to prepare the final drainage map. This drainage map has been scanned and digitized using Arc Info software .the generated digital information is linked with the spatial and attribute data base. Integration of above data using GIS software drainage map has been prepared. This type of drainage map is very useful for decision makers to effective water management and monitoring of water resources based on the predetermined water resources action plan.
