Hi, if I'm not wrong, you can't use the GeoAggrGeometry function with points, it only works with areas. Take a look at this blog post for more info about geospatial functions.
Maybe you should try using a kml file of Qatar in combination with the data points.
I attach a KML I found of Qatar at gadm.org and a Qlik Sense example app. The last thing you need to do is to link the points and areas with a table containing the associations.
Hope it helps. !
