AREA : Lower Mekong Basin, including: - Cambodia (LMB part) - Laos (LMB part) - Thailand (LMB part) - Vietnam (LMB part); SOURCE MAP : Cambodian part: 1:100,000 scale topomaps UTM Projection North-eastern part based on US Army 1:250,000 topomaps Lao part: 1:100,000 scale topomaps Gauss Projection Thai part: 1:50,000 scale topomaps UTM projection Vietnam part: 1:50,000 scale topomaps UTM projection; SOURCE DATA SET : Cambodian part: surveyed part: Field survey and reinterpretation of 1:50,000 scale Vietnamese soil mapping North-eastern part: 1:1 million Agro-geomorphological mapping (1977) based on Landsat Imagery (1975-76) interpretation and 1:1m soil mapping from Crocker 1962. Reclassification of FAO 1974 soil units to FAO 1988 Lao part: Field survey and reinterpretation of older 1:250,000 soil maps. Interpretation of 1:1m geology maps, satellite imagery, forestry and landcover mapping (1989) and 1:30,000 aerial photos Thai part: Field survey and aerial photo interpretation of worldwide series taken before 1960. Vietnam part: Field survey as corroboration of regional 1:250,000 scale soil maps (1986-1995) - themselves based on district 1:25,000 soil mapping. Also Landsat imagery (98-00), 1:250,000 Land use maps (1998 & 2000) 1:250,000 scale topo maps; SOURCE AGENCY : Cambodian part: Agriculture Soil Unit (ASU), Department of Planning, Mimistry of Agriculture and Forestry Lao part: Soil Survey and Land Classification Centre (SSLCC), Mimistry of Agriculture and Forestry Thai part: Soil Survey and Classification Division, Land Development Dept., Ministry of Agriculture and Cooperatives Vietnam part: Integrated Resources Mapping Center (IRMC), Sub-national Institute of Agricultural Planning (Sub-NIAPP) GENERATION : FAO\UNESCO classification system (1988) was adopted as the MRC standard classification Cambodian part: Generated from fieldwork with some reclassification of 1:50,000 soil mapping. NE from 1:1 million mapping Lao part: 1:250,000 scale soil mapping Thai part: Original soil map at the scale of 1:100,000 were generalised and made corelation of soil type into smaller scales at 1:250,000 Vietnam part: Reclassification of 1:250,000 soil mapping; STATUS : Last update: June 2002 Completion status: % (100 = complete); COMMENTS : Soil mapping data derived from different sources, therefore accuracy varies from country to country. Most detailed and accurate data from Thailand and Vietnam Laos and Cambodia not as accurate. NE Cambodia derived from 1962 1:1m scale mapping 2 types of Mapping Units -Homogeneous (1 soil unit only) - Association (2 soil units, assume 60/40 split) Detailed information is limited. Data can be used for regional planning purpose only For mapping, it recomments to use three fields named "Main Legend", "Main Soil Name" and "Main Soil Name Legend"; VECTOR : Topology types: polygon;
