REMOTE SENSING AND GLOBAL POSITIONING SYSTEM ********************************************************** GEOGRAPHIC INFORMATION SYSTEM(GIS). ********************************************* GEOGRAPHIC INFORMATION SYSTEM (GIS) ALSO KNOWN AS GEOSPATIAL INFORMATION SYSTEM OR GIS HAS ARRIVED ON THE CARTOGRAPHIC SCENE WITH TREMENDOUS IMPACT DURING THE PAST FEW YEARS. WHAT IS GIS ? WHY SHOULD CARTOGRAPHERS BE INTERESTED? THE INTERACTION OF GIS AND GEOGRAPHY, IT IS NECESSARY TO DESCRIBE THE PROFOUND EFFECT OF DIGITAL TECHNOLOGY ON GEOGRAPHY. IN THE USE OF ANALOG TECHNOLOGY, THE MAP SERVED TWO FUNCTIONS. I. STORAGE MEDIUM FOR SPATIAL DATA. II.COMMUNICATION MEDIUM BETWEEN HUMANS ABOUT SPATIAL RELATIONSHIPS. DIGITAL CARTOGRAPHY HAS SEPARTED THESE FUNCTION INTO I. DIGITAL DATA BASE CONTAINING SPATIAL DATA II. ABILITY TO CREATE MAPS FROM THAT DIGITAL DATA THROUGH AN AUTOMATED SYSTEM ONE SUCH SYSTEM IS CALLED GIS. IN THE SIMPLEST TERMS GIS IS THE MERGING OF CARTOGRAPHY AND DATA BASE TECHNOLOGY. MANY DEFINITIONS FOR GISHAVE BEEN WRITTEN AND UNIVERSAL ARRANGEMENT ON A DEFINITION IS STILL EVOLVING. WE TAKE A DEFINITION FROM THE U.S FEDERAL INTERAGENCY COORDINATION COMMITTEE (188)GIS IS THE SYSTEM OF COMPUTER HARDWARE, SOFTWARE, AND PROCEDURES DESIGNED TO SUPPORT THE CAPTURE, MANAGEMENT, MANIPULATION, ANALYSIS, MODULARITY AND DISPLAY OF SPATIALLY REFERENCED DATE FOR SOLVING COMPLEX PLANNIN AND MANAGEMENT LROBLEMS.
