# Source Maps
Each dump has a .map file associated with it. These source map files are equally structured as the dumps themselves. However, instead of numerical data, they contain flags which identify the original source of an observation or aggregation.
To request a station's map file, use the following URL:
https://bulk.meteostat.net/v2/monthly/{station}.map.csv.gz
Please replace {station} with the ID of a weather station.
