The isolated, high-altitude regions of the Cardamom and Eastern Highlands host endangered wildlife. Topographic maps help conservationists track illegal logging, map watersheds, and enforce boundary lines for national parks.
A smaller range extending south from the Cardamom Mountains, reaching elevations that catch heavy monsoon rains.
Understanding Cambodia’s terrain through spatial maps is essential for managing its unique hydrology, agricultural sectors, and climate vulnerabilities. This article provides an in-depth analysis of Cambodia’s topographic features, regional elevation models, and major hydrological networks.

. Understanding its topography is key to grasping how its culture, agriculture, and water systems—specifically the mighty Mekong and the Tonle Sap—function in harmony. 1.

The topographic map of Cambodia is more than a navigational tool; it is a historical document and a blueprint for development. The transition from the hand-drawn triangulations of the SGNK to the digital elevation models of the 21st century marks a new era in Cambodian geography. However, the enduring relevance of older maps for land rights and historical comparison creates a unique challenge: the need to bridge the "datum divide" between legacy local coordinate systems and modern global positioning. As Cambodia continues to develop, high-quality topographic data will remain the foundation upon which infrastructure, environmental conservation, and land administration are built.
The heart of the country is the Central Lacustrine Plain. This area sits mostly below 30 meters above sea level. It is a flat, fertile expanse created by centuries of sediment deposits from the Mekong. In the center of this plain lies the Tonle Sap, the largest freshwater lake in Southeast Asia. During the monsoon season, the Tonle Sap River reverses its flow, causing the lake to expand to five times its dry-season size, a phenomenon clearly visible on relief maps as a massive floodplain.
The most dramatic topographical feature of Cambodia is the Cardamom Mountains (Chuor Phnom Krâvanh) and the Elephant Mountains (Chuor Phnom Damrei). Located in the southwest, this is the wettest region in the country and contains the highest peak in Cambodia:
The Mekong enters Cambodia from Laos at the Khone Phapheng Falls, dropping into a deep, low-gradient valley.
