Frequently asked questions
I am an OpenStreetMap mapper and would like to map cell towersOpenCellID mainly collects MCC, MNC, LAC, and CID information combined with a GPS position.
In addition, one of the basic rules of OSM is to map visible things. This is not the case here as MCC/MNC/LAC/CID are not visible in most cases. The most effective way to contribute to OpenCellID is to use one of the smartphone applications listed here and to collect measurements while mapping something else. |
