HABID: A remote sensing Habitat Interpretation database The overall objective of HABID is the retrieval and exchange of information to advise remote sensing experts and service providers Folie 17 > Vortrag > Michael Bock
Motivation: Which nomenclature to use? On European scale no common habitat classification key fully suited to remote sensing of habitats exists Which sensor to use? which sensor is suited for a specfic habitat mapping task what is the minimum mapping for a habitat by a sensor which time of the year is feasible or are multi-seasonal data are necessary Which interpretation guidelines to use? Besides CLC no Interpretation guidelines available that are focus on remote sensing of habitats Folie 18 > Vortrag > Michael Bock

Mapping ALL sites, or a sampling approach? Natura 2000 sites Some are very small and species-specific Others are national park in size Different scales Complex geographic distribution Different conservation problems Subsidiarity responsibility to monitor them difficult to achieve harmonised objective approaches to mapping and monitoring (even field mapping) Folie 28 > Vortrag > Michael Bock
Some Conclusions Remote sensing already IS a reliable supplementary - data source for monitoring of habitats IF the limits and constraints are considered Requested level of detail by the users needs advanced information sources: multitemporal, hyperspectral SAR and optical sensor combinations Reliable in-situ data for calibration of RS-based techniques are necessary A better knowledge exchange between researchers / providers / users Monitoring habitats outside Natura 2000? RS-techniques will only go operational if a tight integration with the countries geo base data and existing mappings is achieved. Cadastral and environmental spatial data supply, storage and distribution needs to be harmonized (Airborne, Satellite, Field mapping) Folie 29 > Vortrag > Michael Bock
