Cambodia is currently catching up with modern cartography. In 1994, the Government of Finland funded aerial mapping of the Mekong River, and GPS monuments were established around Phnom Penh by French mapping agencies. Today, efforts focus on and GIS databases for disaster management. The Kingdom of Cambodia has prioritized establishing a National Spatial Information System to move beyond the outdated 1960s maps.
A detailed topographic map divides Cambodia into four distinct, primary geographic zones based on elevation and landforms. The Central Plains
However, during the Vietnam War and the subsequent Khmer Rouge regime (1975–1979), mapping fell into disrepair. For decades, the Royal Government of Cambodia relied on repurposed wartime maps (often 1:50,000 scale created by the US Army Map Service). Today, modern topographic mapping is undergoing a digital revolution, led by the Japan International Cooperation Agency (JICA) and the Ministry of Land Management, who are producing high-resolution digital elevation models (DEMs) for land titling and water management. topographic map of cambodia
History and topography are inseparable in Cambodia.
The Mekong River enters Cambodia from Laos in the north, flowing directly south past Phnom Penh before splitting into branches and entering Vietnam. The river cuts a wide path through the eastern plains, leaving rich volcanic mud and fertile silt along its banks during annual floods. The Tonle Sap (Great Lake) Cambodia is currently catching up with modern cartography
The lake drains into the Mekong River, shrinking to an area of about 2,500 square kilometers and a depth of 1 meter.
These digital datasets have powered a new generation of applications. One compelling example is the , a 3D-printable STL file based on SRTM data. This allows users to physically print an accurate, raised-relief map of Cambodia, bringing the Cardamom Mountains and the Tonlé Sap basin into tangible, three-dimensional form for educational or display purposes. The Kingdom of Cambodia has prioritized establishing a
