Integrating Remote Sensing Data with Other Geodata (GIS Approach)

Abstract

The purpose of integrated multidisciplinary investigations is to study a system or phenomenon using several approaches and as many attributes as possible or required, in order to obtain a more comprehensive and clearer picture. The growth in computing and data-processing capabilities, coupled with advances in geographic information system (GIS) technology and its integration with geostatistics, has played a very important role in developing integrated geo-exploration approach. Here only raster GIS is discussed. Besides remote sensing data, various types of geophysical data, geochemical data, topographic data and thematic data (vegetation, soil, groundwater etc.) can be integrated in and collectively analysed. Various GIS tools and classification approaches can be adopted.
