GeoNames Forum

Hi all, first of all: I am new to this topic and forum. So it could be possible I do easy mistakes.

I do calculation on the latitude and longitude. But I get strange results. Some look ok but many are more far away than e.g. 30 km. Like munic.

I gave the php/mysql code to chatgpt and it says maybe the data in database is wrong. The readme txt says its wgs84 data.
Example:
The values "522061" and "146241" do not seem to be in the common format of geographic coordinates in the WGS84 system. Usually geographic coordinates are expressed in degrees, with longitudes having values between -180 and 180 and latitudes having values between -90 and 90.

Can anyone help me?
