Types of Resolution in Remote Sensing

In Remote Sensing, the image resolution refers to the amount of information available in a satellite imagery. There is four types of resolution in satellite imageries i.e. Spatial, Spectral, Radiometric and Temporal resolutions. These four types of resolution in remote sensing determine the amount and quality of information in an imagery. 1. Spatial Resolution Spatial … Read more

Relevance and Criticism of Industrial Location Theory

Alfred Weber, a pioneer of locational analysis in Geography, introduced the Theory of Industrial Location in 1909. Weber combined economic parameters with spatial parameters to arrive at a profitable location for industries. It is also known as Least Cost Theory because this theory tries to find a location of least cost for an industrial location. … Read more
