Adding OpenLayers map to Mapping module.

Omeka S Modules
1

I am very new to both Omeka S and GIS-based map development, but I wanted to pose this question here just to gauge the possibilities of achieving what I envision. I am developing a map in QGIS that plots statistical data onto a map of the U.S. divided by county, and would like to integrate that map into an Omeka S site. QGIS can generate an OpenLayers, web-compatible version of the map, but could that be linked to the Omeka S Mapping module? I have read that users can add GeoJSON, WMS, or IIIF layers to the map, but I think the GeoJSON files I would be working with are too large to be a layer in Leaflet.

Any information about what I can customize/add to the Omeka S Mapping module would be greatly appreciated!

How big are your GeoJSON files? Have you tried adding one to a Mapping page block? It may work.

I was able to condense the basic outline of all the counties to about 12 MB, and Omeka loaded it as a layer flawlessly (and without slowing down the response time too much). Thank you for the advice. Ultimately I am aiming to use a WMS overlay, but it is helpful to have the GeoJSON loaded.
