In 2021, FAO launched the land cover legend registry (LCLR), the world's first repository of harmonized national, regional, and global land cover legends, adhering to ISO 19135 standards. This online catalog offers access to land cover legends prepared in line with ISO 19144-2 using tools like LCCS and LCHS software. Integrated into FAO's Hand-in-Hand initiative, the LCLR enables import of legends to their cloud platform for earth observation data processing via SEPAL, fostering opportunities for global-to-local natural resource monitoring enhancements. The accompanying publication details LCLR functionalities and provides guidance on creating legends in various file formats using different software.
