OpenCellID

OpenCellID is the biggest opensource database of CellIDs and is generated on the cloud, thanks to applications supporting the OpenCellID API.

More than half a million of cells are discovered worldwide, with nearly 50 millions of measures.

The home page of the project is here: [1]

Code is hosted on Google Code, while data is available both from the API or downloadable completly as a CSV file.

A German version of OpenCellID is coming soon on www.opencellid.de
