GEOINFORMATION ANALYSIS FOR CONSERVATION: EXPERIENCES WITH OSS IN THE NATURAL PARKS OF BARCELONA
Open Source Software (OSS) has become popular in the analysis of geodata for applications in Ecology, and Environmental and Biological Conservation. OSS is much more than just a cheap solution for disciplines that are most often under the stress of scarce funding, it has become the basis for the development of a community in which cooperative support is spiced with exciting and fruitful debate. The interphase between users and developpers of OSS is becoming wider and fuzier, providing an excellent environment for scientific and technical advance. In this contribution, we present some examples of projects that we have carried out in Natural Parks of the Province of Barcelona, including classification based on image segmentation, use of calibrated satellite vegetation index to monitor recovery after fire, multicriteria analysis to rank and select abandoned fields for restoration, generalization of vegetation maps using a double-criteria hierarchical clustering and processing of infrared imagery acquired by a miniUAV. Finally, we will point out those subjects for which we have felt that OSS solutions are still missing.
