Using Landsat Images to Detect Land Cover Change and Associated Impact on Food Security in the Neighborhood of Surface Coal Mines
2015
Abstract
This paper deals with integration of the landcover data and the satellite images from the Landsat program. The scenes from Landsat (5, 7 and 8) are used to explore land cover changes through several decades.
Spatial features from the classification are arranged in map layers and stored in a data cube with two dimensions formed by the (x) and (y) spatial axis of the image display, and the third (z) formed by the time of acquisition of the image. The data cube is complemented by spatial data from landcover research, and by output layers for visualization.
