TR-159 : Geographic Information system using ilwis

Abstract

The demand for the storage, analysis and display of complex and voluminous spatial data has led, in recent years, to the Use of computers for data handling and the creation of sophisticated information systems. Effective use of large spatial volume is dependent upon the existence of efficient systems that can transform these data into useable information. Geographic

Information System (GIS) is designed to accept large volumes of

spatial data, derived from variety of sources, including remote

sensors and to efficiently store and retrieve, manipulate,

analyse and display these data according to user defined

specifications. In this report all of these components are

covered in different chapters alongwith a case study.

The present report has been prepared by Sh. S.K.Jain and

S.K. Goyal , Scientist 'B' and is a part of training which they

obtained at International Institute of Aerospace Survey and Earth

Sciences (ITC), Enschede,The Netherlands within the frame work

of Indo-Dutch Training Program on water management (WAMATRA

PHASE-II).
