Tower collector rule
(sh.itjust.works)
Tower Collector is an app to help contribute mobile tower data to Mozilla Location Services and OpenCellID, so that its open to all instead of a few large companies. Both of them are open source projects.
This data can be used for estimating location without GPS for example.
