The blue rectangle shows the area represented by the GeoDNA code. Increasing the "precision" (which is the length of the GeoDNA code) will shrink the size of the rectangle by 1/4.

All GeoDNA codes within the blue box share the same prefix.


Scroll around and change the zoom level to see how the GeoDNA codes map onto the surface. Note, for example, that they are more elongated nearer the poles, more squat nearer the equator.

The grey area represents the GeoDNA "neighbourhood" around the GeoDNA code. You can easily calculate this using the API, allowing you to do fast radius searches with no trigonometry.
