摘要：It was possible to identify the areas of urban expansion, the growth axesand the urban land use of Belo Horizonte Metropolitan Area (BHMA) , Brazil,using TM and SPOT imagery. The information extracted from SPOT data and TMdata were compared.The various bands of SPOT and TM data area were interpreted and classifiedinto 8 classes. To evaluate the quality of the products from TM and SPOTvisual and digital classification are done. The visual interpretations areevaluated by a field survey, to check some information, and the digitalclassification are evaluated by the MAXIMUM LIKELIHOOD classifier.The visual interpretation of SPOT imagery provided better details andbetter mapping accuracy. The comparation between the TM digital imageclassification and SPOT digital image classification didn't show thevariability of details existent between them.The areas of urban expansion and the principal sectors of BHMA growth areidentified through the mUltidata MSS imagery and TM imagery.This research showed the usefulness of SPOT data for urban monitoring
