Intention & Procedure: change-detection on two national parks of
a world heritage site using remote sensing fieldwork on the protected areas itself and
in the surroundings classification of the satellite scenes analyse trends of vegetation, landuse and
encroachment concerning the pressure on the national parks
period of time: approximately the last 30 years in three steps (1979, 1990 and present)

Aims of the project:
1) Use of remote sensing to help creating standards for monitoring of world heritage sites with the focus on tropical forests
2) Provide assistance with assessing risks and developing a corresponding action plan because of increasing pressure on the national parks
3) Help making the local population (decision makers, students) aware of problems and threats and involve them in the realisation of counteractive measures

forest complex of Thailand remaining and species-rich rainforest
habitat types of different altitudinal zones also a wide ranged tropical fauna with
endangered species
