Yesterday, I provided an example for how to load GeoJSON from the City of Prince George Open Data site to your Google Maps API web map. You can also load imagery through OGC WMS. Here is an example showing how to do so.
Note: I recycled most of the code from GISDoctor.com.
The City of Prince George recently unveiled the new City Open Data website, providing access to an impressive selection of spatial (and some non-spatial) datasets. Although these datasets have been available for some time on the old open data catalog, they are all now also available as GeoJSON, GeoService, and OGC WMS.
Here‘s an example of how you can load a Prince George GeoJSON layer through the Google Maps API.
