http://www.perrygeo.com/tissot-indicatrix-examining-the-distortion-of-map-projections.html WebNicolas Tissot’s indicatrix is designed to quantify the level of distortion in a map projection. The idea is to project a small circle (i.e. small enough so that the distortion remains relatively uniform across the circle’s extent) and to measure its distorted shape on the projected map. For example, the following block of code shows the ...
