The iand use information in the available sources is very vague. 
More detailed data is needed. Therefore, an IKONOS2 image 
(Spaceimaging©; www.spaceimaging.com) was acquired 
covering most parts of Dongbeiwang. The 1 m panchromatic and 
4 m multispectral resolution of this image enables the 
classification of large scale land use data (Bareth 2001). The 
results of the DGPS mapping were used for geo-rectifying the 
image and for a supervised land use classification by using 
IDRISI32 (www.clarklabs.org). In Fig.2, the IKONOS2 image is 
displayed with the land use map 1:10,000.
