Phoca Maps is a Joomla! component. It displays Google Maps or OpenStreetMap on your site.
There are two different ways how to display maps:
- Google Maps - maps run with Google Maps API 3. You need to create Google Maps API key to display maps on your site, see: Creating Google Maps API Key article.
- OpenStreeMaps - maps run with OpenStreetMap API. You don't need any API key to display basic maps on your site. In case you need e.g. routing feature, etc. you can use API of specific OpenStreetMap services like Mapbox or Thunderforest (you need to sing up for these services).
