%X Many agencies have been producing land cover data with different definition, number and type of classes. In order to compare two data sets created using different legends and/or classification systems, it is necessary to carry out a harmonization process. This work aims to present and evaluate a harmonization process between two Land Cover Meta Language (LCML) formalized legends. To this purpose, two types of land cover legends obtained from maps from satellite images generated for Amazon region were analyzed and had their legends harmonized based on two approaches: 1) considering the semantic meaning of the classes and; 2) considering LCML descriptors and thresholds. The land cover maps generated with optical and SAR data were reclassified considering the harmonized legends proposed and were evaluated in terms of accuracy and agreement of the classes. For this analysis it was necessary to convert the land cover mappings to the same format and projection, and to solve problems of miss-registration. Although the harmonization process has shown to be effective, not all of the classes from TerraClass legend could be harmonized to the classes of the two maps analyzed.
