Description :
The AA. analysed the suitability of multi-temporal Landsat TM images in habitat mapping, in particular for the discrimination of semi-natural grasslands. The results showed that even patchy agricultural mosaics can be coarsely mapped with Landsat TM and that the use of multi-temporal imagery notably improves the classification results. After a comparison, the compositional indices, diversity index and patch sizes gave similar results on both scales. Finally, the habitat pattern of the study area was described using the calculated compositional, structural and environmental indices, and 3 main landscape types were identified.
