Abstract

Remote Sensing provides digital images of the Earth at specific wavelengths of the electromagnetic spectrum. Various features on the earth either natural or man made give distinguishable signature of the electromagnetic radiation. Classification of the remote sensing data into different features aid in various application of the data. For instance, land cover, vegetation type, terrain conditions aid in agriculture etc. There are many other applications of remote sensing data in forestry, ecology, urban & land use planning, hydrology, water & waste management, environment, transportation, archaeological investigations, military observations and geomorphological surveying etc apart from geological applications.
