17 LAND USE CLASSIFICATION IN BAVARIA FROM AERIAL PHOTOGRAPHS AND ERTS-1 IMAGERY Horst S. Helbig DFVLR Institute of Satellite Electronics, Oberpfaffenhofen, Germany ZUSAMMENFASSUNG ERTS-MSS-Aufnahmen von Bayern werden nach einem Analogverfahren mit Hilfe eines Farbabtasters maschinell verarbeitet und ausgewertet. Dazu ist es notwendig aus den S/W-Bildern der drei Kanäle MSS 4, 5 und 6 ein Farb bild zusammenzusetzen. Man erhalt bei Abtastung des Bildes die radiometri schen Werte der drei Spektralbereiche gleichzeitig für jeden Bildpunkt. Diese werden in einem Farb-Prozeßrechner miteinander kombiniert und ermöglichen so die Erkennung der spektralen Signatur. Der Spektralbereich MSS 7 dient im wesentlichen zu einer Diskriminierung zwischen Land, Wasser und Wolken. Nach diesem Verfahren wurde eine thematische Kartierung von folgenden Objekten durchgeführt: Oberflächenwasser, Wassertiefe, Wasserverschmutzung, Siedlungsgebiete, Verkehrsflächen, Vegetation, Nadel- und Laubwald, Gras land und landwirtschaftliche Nutzflächen. Wenn das räumliche Auflösungs vermögen der ERTS-Aufnahmen ausreicht, können einzelne Typen landwirt schaftlicher Vegetation unterschieden werden. Eine bessere Unterscheidung landwirtschaftlicher Kulturen erfolgt durch Texturanalyse farbiger Luftbilder. SUMMARY ERTS-MSS images from Bavaria are analyzed using a colour scanner for machine processing. It is necessary to make colour compositions of the three b/w pictures from MSS channel 4, 5 and 6 (7). By thisscanning the picture, the radiometric values, i.e. the colour densities, of the three spectral channels are obtained simultaneously for each picture element. The three signals are then correlated in a special analog colour computer and gradation processor. The channel MSS 7 is used for land/water/ cloud discrimination. By this, thematic mapping of the following objects is made: surface water, water depth, water pollution, urban areas, vegetation, conifer and deciduous forest, grassland, agricultural vegetation. If the spatial resolution of the ERTS image is sufficient, different types of agri cultural vegetation are discriminated. Aerial photographs are used for better discrimination of agricultural vegetation by texture analysis.
