ABSTRACT
This paper presents a methodological approach to combine land use information obtained from different processing
methods. The first one is a traditional multispectral classification of multitemporal LANDSAT TM images. The second
is a textural analysis of high-resolution panchromatic images obtained from aerial ortophotoimages. Both are combined
using Decision Theory approach to get the best from each classification. Some test results are presented in order to show
the improvement obtained.
