**Support / Coordinates not accurate to OSM?**

« **on:**February 26, 2020, 07:56:05 AM »

Kronnect,

I am attempting to place icons on my huge globe (scale of (12756274, 12756274, 12756274)) for significant landmarks around the world and I found that the coordinates transformed by the calculator don't seem to line up with the position of the feature in OSM.

For example:

Basilica La Sagrada Familia in Barcelona, Spain

Latitude: 41.403545

Longitude: 2.174409

The calculator converts this to a spherical coordinate of:

x: -0.02845875

y: 0.6613583

z: 0.7495301

Multiplied by the earth radius (half the scale of my globe) of 6378137:

x: -181513.80634875

y: 4218233.8434871

z: 4780605.6634237

I attached an image showing a cube I located at the above coordinates with "Plotted Location" next to it. I indicated the actual approximate location of the Basilica with a red dot. I also tried several other landmarks and they seem to be alright on the longitudinal axis but the latitudinal axis appears to be slightly off.

I am using the Beta version V13.4 B7

Am I doing this right? or is there a more accurate way to calculate the position?

Thanks!
