Following independence, the Service Géographique National Khmer (SGNK) was established. Between the 1960s and early 1970s, the SGNK produced the most comprehensive "legacy" maps of the country. These maps, often created using aerial photography, remain a vital baseline for legal and land tenure disputes today.
