You may not need an icon pack at all. Each GeoDirectory category has its own map marker, and GeoDirectory can generate one from a Font Awesome icon and a colour. You can also upload any image you like as the marker.

Let GeoDirectory generate the marker

1. Go to Places > Place Categories and edit a category.
2. Leave Map Icon empty.
3. Choose a Category Icon and a Category Color.
4. Click Update. The category’s listings now use a marker made from that icon and colour.

Upload your own marker image

To use an image instead, click Select Icon under Map Icon on the category and choose an image from the media library. A small PNG with a transparent background works best. Free map pin icons are easy to find on icon sites, so check the licence allows use on your site.

The default marker

Listings in a category without a marker use the default marker icon. You can change it at GeoDirectory > Settings > General, in the Map Settings section (click Show Advanced to see it).

See Create a Category for the other category settings.
