Lack of icons

[EricL]

I think that there are a lack of icons on google map. It does allow one to create a category type that's not in the list but as there's no pre-set icons for this, it doesn't show up on the map

Place labels are a feature of Google Maps that surfaces great content such as landmarks, businesses, and tourist attractions on our base map data. To see place labels on Google Maps, zoom in to a level similar to what is shown below. All of the icons in our base map data are clickable, allowing you to find out more information about each place.

The place labels shown on Google Maps are determined algorithmically based on a large number of factors. One factor these algorithms consider is the accuracy of the business information and the richness of the content associated with the business.

Verifying your business (if you are the owner) improves the chances that your business will display with a place label.

If you see a place label that is in the wrong location or that contains incorrect information, you can report a problem. It may take up to one month for any reported issues to be fixed, so thanks in advance for your patience.
