EARTH OBSERVATION / GIS








Assessment of Natura 2000 habitat classes is commonly based upon experts 'best' knowledge on distribution, extent and quality. On a national scale, assessment of certain habitat classes can be quite difficult - there will be no maps or statistics to lean on, thus, assessment can easily be related to 'intelligent guessing'.




A combined scenario of 20 Natura 2000 habitat classes as well as other main cover types. 



By the use of Earth Observation and GIS techniques, it is possible to provide decision support to experts to locate potential habitat areas as well as establishing an objective basis for jugdment of the national extent. In Eastern Europe many of Natura2000 habitat classes can be sub-divided into classes related to 4' and 5' level of CORINE which in many cases gives a better representation of eco-environment driven by geo-botanical relation.


In Lithuania we used digital remote sensing and GIS techniques to estimate the extent of more than twenty Natura2000 habitat classes. National habitat specialists were involved in the classification procedures by visual interpretation of classes, digitalization of specific habitat areas, integration of existing field data and discussion on criteria's for habitat mapping that should be modeled in GIS.


The analysis and simulation of habitats include the use of national vector layers on forest, water courses, bogs, land use and Digital Elevation Models.


The assessment of e.g. Taiga was within few percent from what could be interpreted from national forest statistics, overall the result was used to identify potential new habitat areas and as such supported the assessment of actual extent.




An example of Landsat based Natura2000 classification of the UNESCO World Heritage Site- Curonian Spit. The potential habitat area has been masked out and the veracity of single habitats has to be merged.
