How to add your own map regions
Flourish offers a selection of different blueprints to start with. If the country or region you'd like to display isn't one of them, you can add it yourself.
- To add your own regions to a projection map, you will have to upload them in a GeoJSON format. The file should contain a FeatureCollection with each feature being a Polygon or MultiPolygon in unprojected (WGS84) coordinates. You can upload your GeoJSON by dragging it to the editor or selecting to import it.
- If you upload your own GeoJSON and your map doesn't seem to display, the coordinates in your GeoJSON are probably not WGS84. To transform your coordinates to be WGS84, you can use the free online tool mapshaper.org.
- Each feature will become a row in the datasheet with the geometry in the first column and metadata (properties) in subsequent columns. If you would like to remove a region, you can delete the corresponding row in the Regions datasheet.
- You can search the web for GeoJSONs of the regions you would like to upload, or transform TopoJSON or shapefiles using tools like mapshaper.org.
