I am looking to display a parish boundary overlay on a map on OSM.
I have a geojson file and a wkt file from MapIt with the boundary points but I have no idea where to start.
The map is at OpenStreetMap
Hi !
If the data is already in OSM, you just have to “select” it on the website, like this boundary (to find it, I used the find object button
, somewhere on the map you linked to).
Otherwise, you’ll need to use an external tool to display your own data on top of OSM, like FacilMap (simple, easy to use), or uMap (way more versatile and kind of complicated). There are others, but that’s the two I know best, and both can import geojson. Please ask here or in a new question if you need more specific help.
Best regards.

Many thanks. I’ll take a look at FacilMap. I’m using Leaflet on another map.
Oh then you should be able to use leaflet directly to display your geojson (some documentation).

That sounds even better. Thanks for the link to the documentation.

The level 10 boundary (which equates to a civil parish in England) is Relation: ‪Brickendon Liberty‬ (‪3585326‬) | OpenStreetMap
I found it by selecting Query Features from the menu, clicking in the village and then selecting Suburb boundary from the enclosing features.
Such boundaries are pretty complete in GB.
