This data set (LCDB v5.0Version Trace) allows users to track changes back to the previous version (v4.1), and to reconcile derived quantities, such as the total area of a class in a region, to those derived from the earlier LCDB version. Additionally the authority (and date) for mapping the change is recorded in this database where such a change has been manually mapped.However sometimes when a feature has been removed, and the change area becomes part of a larger "background", the EditDate will pertain to the background area. DO NOT use this dataset to assess real vegetation change over time. Rather use the latest available LCDB version which will contain vegetation cover for all timesteps. This Version Trace dataset is only provided to help reconcile with an analysis done on an earlier version of the LCDB. Similar datasets were provided to trace LCDB2 ==> LCDB v3.0, LCDB v3.0 ==> LCDB v3.3, LCDB v3.3 ==> LCDB v4.0, and LCDB v4.0==> LCDB v4.1. Note however, we earlier called the dataset "Change" rather than "Version Trace", e.g. "LCDB v4.0 Change".
