Updating allows you to replace the map source data file of a map on the server running DAS with another file. Your new map source data file must have the same delimiter, number of columns, and overall structure as the existing map data source file in order for the map to function properly after the update. The new map source data file should only differ from the existing file by the values that appear in the columns. If the new map source data file has a different structure than the existing file, use the Edit feature to update the map definition.
Map updates can be performed on demand from the Sentinel Control Center. To set up an automated process to update map data, you can run an equivalent process from the command line using map_updater.sh or map_updater.bat.
There are two map locations: the location referenced by the Event Map Configuration (which is a user-defined location) and the location where Sentinel stores its internal representation of the map (<install_directory>/data/map_data). The internal representation of the map should never be manually updated.
