APPLICATION OF REMOTE SENSING AND GIS IN ANALYSIS OF TERRAIN VARIATIONS: A CASE STUDY
Keywords:
..Abstract
Remote sensing and Geographic Information System (GIS) together provides a powerful base for detailed mapping, database generation and analysis more effectively in the planning and management of natural resources like land, forest and water etc.. For this purpose terrain variation has an important role in decision making. An identity or signature of an area is always recognized by its hydro-geomorphic and topographic characteristics. So the prerequisite step is to understand the area's expression's in terms of its terrain characteristics. Most maps and GIS data deal with two-dimensional (X-Y) perspectives (e.g., flat maps depicting a region). However, GIS is also very good at incorporating the Z values, as well, such as elevation or any raised value of an attribute (e.g., population). X, Y, and Z are the principal spatial data coordinates in GIS (Davis, B.E., 2001).
The present paper aims to explore the characteristic terrain variations in Chakia tahsil, which is part of Chandauli District of Uttar Pradesh.
