Map Projection Playground

This demo draws finite circles as a Tissot's indicatrix approximation

Real Tissots's Indicatrices are always ellipses since they are infinitly small and are only scaled for presentation

In contrast the circles in this implementation have the actual size of circles on a sphere as presented, yet for analog use the varible is named tiss none the less. Go on and play around with the segmentation (tseg), direction (tdir) as well with the density of the graticules (grat).

Also don't miss to change the projection in the dropdown menu to see the distortions at work
