CartoType GL is the graphics-accelerated version of CartoType. It gives you a smooth, fast, fluid user experience, with no delays when panning or zooming the map.

What can I do with CartoType GL?

You can do everything you do already! The standard CartoType API is available, and you can use the same map data (CTM1 files) and style sheets that the standard version of CartoType uses. And unlike some mapping frameworks, which require you to use the Web Mercator projection, CartoType GL allows you to use any projection.

How it works

CartoType GL uses two things to give you that extra speed. Multi-threading uses several processor cores at once to fetch the map data. The Open GL ES graphics language gives access to the graphics acceleration chip on the device. All modern mobile and desktop platforms now support graphics acceleration.


CartoType GL is available now for iOS, Android, Windows (desktop) and Linux. Contact This email address is being protected from spambots. You need JavaScript enabled to view it. if you’re interested.
