Im trying to add a new layer ( via Leaflet?) consisting of a geojson multi polygon file, im struggling to find which way to do this as a back office function.
the intent is to generate isochrones via a local version of the openrouteservice PI over the top of the layers to establish the limits of each fire station jurisdiction( ie the polygons)
Could you point me in the correct direction please?
I also need to plot the fire stations a an icon which then becomes the origin for the isochrone
