Aspect Ratio for geoaxes

I am trying to set the data aspect ratio for a geoaxes() similar to doing axis equal or axis square in a regular axes(). Any guidance would be appreciated.

Hi Mia,

In MATLAB, for a “geoaxes” object, you cannot directly set an equal data aspect ratio like axis equal due to the nature of map projections. However, you can

1. Try to approximate aspect ratio by setting equal latitude and longitude ranges with “MapLatLimit” and “MapLonLimit”.
2. Use “daspectm('m',1)” to adjust the meridian-to-parallel distance ratio, though it may not be perfect.
3. For precise 1:1 distance ratio, consider an azimuthal projection for small areas.
