| 1:100,000 Cambodian Topographic Maps make use of a number of diverse data sets and types, including land use, river/stream, rail/road, contour, administrative units, infrastructure - temple / school / church / mosque / stupa / post office / hospital, historical site, airport and spot etc. This map series focus on lowland areas of Cambodia, where settles most of the population. |  |
| Cambodian Land Use results from on the interpretation of Landsat TM imagery. There are seven categories: Urban/Built-up areas, agricultural lands, grasslands, shrub lands, forest covers, water features and soils/rocks. These categories consist of totally 40 classifications. Based on this detail, there are another 23 land use types grouped and dissolved for topographic maps. |  |
| Cambodian Geology is about the geology and landforms. It shows the distribution of the rock era and rock categories. The Cenozoic covers the most Cambodia, while the Mesozoic and Pareozoic only outcrop in part of the southwest. The dataset scale is 1:500,000. |  |
| Landsat MSS and Landsat TM/ETM Dataset cover the entire Cambodia. These dataset was from the University of Maryland's Global Land Cover Facility (GLCF). There are totally 20 scenes of MSS, 19 scenes of TM, and 25 scenes of ETM. The web mapping services mosaic these images and show their composites from the infrared, red and green bands. |  |
| Cambodian Administrative Map is based on the second edition Gazetteer of Cambodia, including names and location of villages, communes, districts, provinces, municipalities, and administrative boundaries. The place names are annotated in Khmer and Romanized Characters. The first edition was published by the US Defense Mapping Agency in 1971. Based on this edition, Geography Department, Cambodia released its present Gazetteer (Both Khmer and Romanized at village level) in 1996. |  |
| Cambodian Population Distribution was based on the village-level census of population in 1994. The population distribution and the population density at each level of administrative units was calculated using the above basic census. The map demonstration shows clearly most population settles in the lowland and flooding areas, implying the relationship between human activities and nature source distribution.

| 1:1,000,000 Vector Map Level 0 is the updated and improved version of the Digital Chart of the World. It provides worldwide coverage of vector-based geospatial data. The dataset consists of geographic, attribute, and textual data. There is ten thematic layers: Boundaries, Data Quality, Elevation, Hydrography, Industry, Physiography, Population, Transportation, Utilities and Vegetation. In addition, it includes an index of geographic names that is very helpful in locating areas of interest. |  |
