| Abstract: | In the mid-1990s, we established the national operative dynamic information serving systems on natural resources and environment.
During building the land-use/land-cover change (LUCC) database for the mid-1990s, 520 scenes of remotely sensed images of
Landsat Thematic Mapper (TM) were interpreted into land-use/land-cover categories at scale of 1:100,000 under overall digital
software environment after being geo-referenced and ortho-rectified. The vector map of land-use/land-cover in China at the
scale of 1:100,000 was recently converted into a 1-km raster database that captures all of the high-resolution land-use information
by calculating area percentage for each kind of land use category within every cell. Being designed as an operative dynamic
information serving system, monitoring the change in land-use/land-cover at national level was executed. We have completed
the updating of LUCC database by comparing the TM data in the mid-1990s with new data sources received during 1999–2000 and
1989–1990. The LUCC database has supported greatly the national LUCC research program in China and some relative studies are
incompletely reviewed in this paper. |
