Cambodia's geology is characterized by a mix of sedimentary, metamorphic, and igneous rocks. The country's bedrock is composed of sandstone, shale, and limestone, which have been shaped by millions of years of erosion.

For modern uses, data is invaluable. You can download free shapefiles of contour lines derived from NASA's SRTM (Shuttle Radar Topography Mission) data. The Humanitarian Data Exchange is a vital resource for NGOs working on flood risk or infrastructure in Cambodia.
: These ranges dominate the southwest, creating a natural barrier near the coast.
