 To track a paxcounter device with on board GPS and at the same time contribute to TTN coverage mapping, you simply activate the [TTNmapper integration](https://www.thethingsnetwork.org/docs/applications/ttnmapper/) in TTN Console. The formats *plain* and *packed* generate the fields `latitude`, `longitude` and `hdop` required by ttnmapper.
