The papers by Taillie and Rodriguez deal with problems of summarizing the fragmentation patterns of a landscape into a small number of descriptors. A first step to achieve this difficult target is considering the landscape as the combination of land cover types of a certain nomenclature.

One of the main challenges for the future in the field of landscape indicators, is how to deal with imperfect land cover information. The input for the indicators often comes from satellite image photo-interpretation or automatic classification. Depending on the photo-interpretation specifications or the classification algorithm, the same landscape can yield large patches of the same land cover type or numerous scattered pixels with different labels (speckled effect).

The paper by Stahl deals with guided transect sampling, which is a brilliant idea of ancillary information is available that is well correlated with the target item. When the ancillary information is available that is well correlated with the target item has to be more or less identifiable with radiometric measurements, and happen in relatively large patches. es.
