Information about Macrostrat columns can be accessed through our API.

Column footprints

Column footprints can be downloaded for some or all Macrostrat columns through the /columns API route. This API route can be filtered by many parameters, which drives Macrostrat column filtering.

• The all query parameter will download all columns
• The output format can be controlled with the format parameter, with options json, csv, geojson, geojson_bare, topojson, and topojson_bare.
• geojson_bare files can be opened directly in GIS software such as QGIS
• Not all Macrostrat columns are in our core column dataset. Other columns are held in different "projects," which can be specified using the project_id query parameter. Available projects can be found at the Projects API route.
