I’m working on a project with a Sharon over at Generations Gone By who has a special affinity for the “Places” category of her family history.
The addition of GoogleMap functionality to TNG fueled the fire of this inspiration. There was a need for more place pins…
In TNG>Admin>Setup>Map Settings>Help:Map Settings
Place Levels Pins: Labels and Colors
Each geocode location can be associated with one of six Place Levels (e.g., Location, Town/City, County/Shire, etc.). The labels for these levels can be found in the “alltext.php” file in each language folder, and you may override them in your “cust_text.php” file (also in each language folder).
The pin colors are determined by values set in mapconfig.php. If you would like to change the pin colors, go to the TNG downloads page and download the full palette of 216 different pin colors, then open your mapconfig.php file in a text editor and enter the number of the new pin color next to the corresponding place level variable. Finally, upload the new pin image file(s) to the googlemaps folder on your site.
