Two Mobile Phone / Cell Maps of Leeds

From the OpenCellID Project and Mozilla Location Services, I produced these two maps of parts of Leeds. The areas are merged together based on the network code. It was made using QGis.
I talked about this during Superposition Leeds #008 on 20 May 2015 http://www.thesuperposition.org/event/008/

They look pretty rather than useful, so here they are!
