Digital Processing of Landsat Data for the Preparation of a Land Use Map of the Rural District Surrounding Tuebingen to a Scale of 1:50000

摘要

Based on LANDSAT satellite remote sensing data, a 1:50,000 land use map of the rural environs of Tuebingen, West Germany was produced. The interactive digital image processing system called DIBIAS was used for the image processing. The main algorithms applied were geometrical rectification to Gauss-Krueger coordinates and Maximum Likelihood classification of the image data. The results were combined with both optical and digital topographical information and compared with a conventional vegetation map. An assessment of the usefulness of thematic mapping for regional planning is given. Aspects of data acquisition and the physical foundations of remote sensing are described. The reflection properties of various terrain types, differentiated in the wavelength bands of the electromagnetic spectrum, are discussed. The LANDSAT system and its associated sensing techniques are presented.
