The Paris 2.5D Digital Map Data is available for download!
The dots are the measurements coordinates and the X in above is the emitter location where the coordinate is:
-96.99999, 156.00000, 7.00000
The emitter frequency is 1.8G (GSM) and there is only 1 measurement route, which has 1651 test points. You could however, split the one measurement into two or more i.e. you can use 1 route for model/material calibration and other routes for validation (accuracy).
