Do you only have long-lat info or do you have other information about the points as well, like country or city?

Hi,

There is an add on product available, Qlik Geocoding, that provides complete reverse lookup, from coordinate to address.

If you are only interested to find the country per coordinate, then the QGA operation "Within" can be used. For more info see screenshot and example app.

Thanks,

Patric

What you need is known as reverse geocoding. As Patrick said you can buy an addon Qlik product for that. Or you can try an online service such as Google offers: https://developers.google.com/maps/documentation/geocoding/start?csw=1#reverse. Or you can use other tools. Python for example has libraries for that purpose: https://github.com/thampiman/reverse-geocoder
