The Cambodia national Land Cover time series (2015-2023) was derived from the Biophysical M&E Dashboard tool, being used by USAID/Cambodia to track performance and report on landscape-scale efforts and biophysical conditions on the ground in accordance with quantifying areas of biological improvement and improved natural resource management. The Land Cover was developed through a collaborative effort led by SERVIR-SEA using the Regional Land Cover Monitoring System (RLCMS) approach as well as being under the auspices of the REDD+ task team and the FCPF project in Cambodia to support the FREL. The source of the guideline tool depicts that with this purpose, RLCMS was customized to meet Cambodia's land cover typologies. An uncertainty assessment was integrated in the assemblage process and used Landsat annual composites and training data collected by MOE.
