OpenLayers 3 Google Maps API

Use OL3 and Google Maps together

This GIST provides an example of a Google Maps map with an OL3 map as control, to give users a Google base map with OL3 content on top.

Open the corresponding bl.ock to view the example in your browser.


This integration between Google Maps and OL3 is rough. Do not use it in production!

Why doesn't OL3 include a Google Maps source?

This question very often comes up on the OL3 mailing list. The short answer is because Google doesn't allow us to directly access their tiles. See Paul Spencer's post on the OL3 mailing list for a more complete explanation.

Thank you so much from Shenzhen 👍

I've updated the sample because it fails due to ol.source.GeoJSON removal.
You may want to correct this sample as your GIST seems to be one of the main entry for using Google Maps with OpenLayers 3

Why "don't use it in production "? could it be not supported in the future??

Cannot reach Paul Spencer's post :/ url doesnt work
