Geospatial data for PowerBi or other

Feb 23, 2016
I have been tasked to build a small little dashboard report in powerBI or other that can take erf details as the base layer for an area and then we want to overlay which properties are for example are paying members , and other things they are interested in .

Is there a source of data that is publicly and freely available that would allow me to do something like that.

An example would be the Fibre coverage maps we have in SA:- where is the underlying mapping data coming from?

The solution I need to build is for a non profit community association and would be used by about 5-10 people max.
