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.
