An Extraction and Analysis of Land Elevation and Coastal Area using Spatial Data Mining Techniques in DEMs

Abstract

The earth's land surface is always changing its morphology and characteristics due to its inside and outside movements/activities like earthquakes, volcanic eruptions, tsunamis, cyclones, avalanches, asteroid hits, floods, land sliding, and so on. All these earth's movements/activities are the natural phenomenon and not affected the earth's atmosphere that much which is affecting more than the man made things or global warming. The main causes of increase in the earth's temperature are the industrialization, deforestation, and pollutions which are generating more and more artificial disasters. The melting of land ice such as glaciers and ice sheets are the main reasons of increase in global sea levels and is become a big challenge to the people of cities/villages which are located on the sea coasts. Therefore an attempt is made in this paper to extract and analyse the land elevation data, elevation statistics, number of cities/villages located near the sea coasts in India within a specific distance and elevation classes using spatial data mining techniques in DEMs (Digital Elevation Models). The states wise extracted results of this paper are visualized geographically for better understanding and will be useful to plan, monitor and control the by local administrative of that concern province.
