Abstract: Aim We aimed at producing a uniform ;regional; land cover map of South and Southeast Asia based on ;sub-regional; mapping results generated in the context of the Global Land Cover 2000 project. Location The region of tropical and sub-tropical South and Southeast Asia stretches from the Himalayas and the southern border of China in the north, to Sri Lanka and Indonesia in the south, and from Pakistan in the west to the islands of New Guinea in the far east. Methods The regional land cover map is based on sub-regional digital mapping results derived from SPOT4-VEGETATION satellite data of the years 1998 to 2000. Image processing, digital classification and thematic mapping were performed separately for the three sub-regions: South Asia, continental Southeast Asia and insular Southeast Asia. Landsat TM images, field data and existing national maps served as reference. We used the FAO (Food and Agriculture Organization) Land Cover Classification System (LCCS) for coding the sub-regional land cover classes and for aggregating the latter to a uniform regional legend. A validation was performed based on a systematic grid of sample points, referring to visual interpretation from high resolution Landsat imagery. Regional land cover area estimates were obtained and compared to FAO statistics for the categories and cropland Results The regional map displays ultimately 26 land cover classes. The LCCS coding provided a standardized class description, independent from local class names, it also allowed us to maintain the link to the detailed sub-regional land cover classes. The validation of the map displayed a mapping accuracy of 72% for the dominant classes of ; and crop land regional area estimates for these classes correspond reasonably well to existing regional statistics. Main conclusions The land cover map of South & Southeast Asia provides a synoptic view on the distribution of land cover of tropical and sub-tropical Asia, it delivers reasonable thematic detail and quantitative estimates of the main land cover proportions. The map may therefore serve for regional stratification or modelling of vegetation cover, but could also support the implementation of forest policies, watershed management or conservation strategies at regional scales.
