As part of the Landsat Global Archive Consolidation effort, the first international Multi-Spectral Scanner (MSS) data from Canada has been added to the archive! MSS data, captured by the first Landsat missions, are often the most difficult to ingest and process, but yet can be the most valuable for studies using time series. The Canadian Centre of Remote Sensing contributed the data months ago, but the software to ingest that data successfully was just released in late June. For more information on the consolidation effort, please see:https://www.usgs.gov/landsat-missions/Landsat_Global_Archive_Consolidation.php.
