GIS and its importance in civil engineering

ABSTRACT

PAPER ON GIS AND REMOTE SENSING

INTRODUCTION TO GIS AND REMOTE SENSING

Remote sensing is the process of collecting ,storing ,and extracting environmental information from images of ground acquired by devices not in direct physical contact with the features to be studied . Human is vision of course ,a remote sensing process, since we continuously collect and mentally interpret electromagnetic energy from our surroundings . The images of the ground may be obtained from remote sensing devices, which are carried by spacecraft or space vehicles. The Indian remote sensing program on remote sensing satellites is very useful and is covered . This topic includes concept of Remote sensing technology, capabilities of Remote sensing in water resources ,applications, and various works of various countries in GIS and Remote sensing.

GIS – GEOGRAPHICAL INFORMATION SYSTEM
The application of GIS has increased many folds in many fields . It is widely used as a standard tool in agriculture , environmental management ,forestry, hazard monitoring ,hydrology ,watershed management , land analysis , etc. The introduction of GIS promoted interdisciplinary studies ,both within the natural, environmental, social, and economical sciences. GIS have developed through the conjunction of interests of several specialist disciplines, each with its own view of the world. Cartography, remote sensing, and photogrammetry, architecture and planning , surveying, and computer science have all a role in the advancement of GIS. GIS provide an infrastructure for the examination of complex spatial problems in new and exciting ways . GIS is enabling to handle data at different scale and dimensions ,stores the data ,manipulate and analyze data and displays all forms of geographically referenced information . This topic includes use of GIS in land use planning , land evaluation studies , watershed management.
