Geographic Information Systems (GIS), which formalized a few decades back as a set of computer tools, has now emerged into a powerful planning tool for a myriad of physical and human endeavours: from regional planning to scientific research; from strategic management to decision support system; from disease analysis and prevention to industrial location analysis; and from environmental management applications to military simulations. GIS is now being used across various disciplines and its applications continue to grow. The present volume has been conceived primarily to provide basic knowledge about the currently available GIS technology and its use in solving everyday geographical problems. Indian application cases presented in the book will be of vital use to students and researchers alike. CONTENTS 1. Computer Basics / R. Ram Mohan Rao 2.
