Megjegyzések:The goal of the ChangeHabitats2 project is the development of cost- and time-ef?cient habitat assessmentstrategies by employing effective ?eld work techniques supported by modern airborne remote sensing methods,i.e. hyperspectral imagery and laser scanning (LiDAR).An essential task of the project is the design of a novel ?eld work technique that on the one hand ful?lls thereporting requirements of the Flora-Fauna-Habitat (FFH-) directive and on the other hand serves as a reference forthe aerial data analysis. Correlations between parameters derived from remotely sensed data and terrestrial ?eldmeasurements shall be exploited in order to create half- or fully-automated methods for the extraction of relevantNatura2000 habitat parameters.As a result of these efforts a comprehensive conceptual model has been developed for extraction and integrationof Natura 2000 relevant geospatial data. This scheme is an attempt to integrate various activities within Change-Habitats2 project de?ning pathways of development, as well as encompassing existing data processing chains,theoretical approaches and ?eld work.The conceptual model includes de?nition of processing levels (similar to those existing in remote sensing),whereas these levels cover the range from the raw data to the extracted habitat feature. For instance, the amount ofdead wood (standing or lying on the surface) is an important evaluation criterion for the habitat. The tree trunkslying on the ground surface typically can be extracted from the LiDAR point cloud, and the amount of woodcan be estimated accordingly. The ?nal result will be considered as a habitat feature derived from laser scanningdata. Furthermore, we are also interested not only in the determination of the speci?c habitat feature, but also inthe detection of its variations (especially in deterioration). In this approach the variation of this important habitatfeature is considered to be a differential habitat feature, that can be immediately used in the evaluation of theNatura 2000 sites.The goal of the project is the identi?cation of many potential habitat features that can be extracted or implied fromremotely sensed data, and the development of processing chains to provide data that can be used in the everyday?eld work of ecological site assessment.
