Tonle Sap Map

How to read this map
Its surface lies about 2 m (5 ft) above sea level. Inflows include Tonle Sap River, Sangkae River, Chinit River and Pursat River. It drains through the Tonle Sap River.
The blue outline marks Tonle Sap as mapped by Natural Earth. Towns and cities on the map include Battambang, Siem Reap, Kampong Chhnang, Pursat, Sisophon, Phnom Tbeng Meanchey and Kampong Thom. Labeled countries: Cambodia.
Greens show lower elevations; tan and brown show higher land, with pale tones toward the highest terrain. Shadows emphasize the slopes, and vertical relief is exaggerated so landforms are easier to read. Dashed lines show country borders.
The relief uses Terrain Tiles (SRTM, GMTED2010 and ETOPO1 elevation data). Rivers, lakes, borders and the outline of Tonle Sap come from Natural Earth, and the figures on this page from Wikidata. Natural Earth draws features at a small scale, so the outline is a guide to where Tonle Sap is, not a surveyed boundary.
