10.11.3.3 GeoProjection used in area computation of relatively small regions

https://mathematica.stackexchange.com/landing/r/digest?cta=question&id=301209

Let's define a relatively small region via GeoPosition as follows. 
 pos = GeoPosition[{{48, 9}, {48.0001, 9}, {48.0001, 9.0001}, {48, 9.0001}}, "WGS84"]
