Tissot's indicatrices enable to compare the distortion in maps of Australia drawn with Albers's equal-area (top) and Lambert's conformal (bottom) conic projections. Points along green standard parallels — 15°S and 35°S (left) and 25°S (right) — suffer from no distortion, areal or angular. Notice in the equal-area conic how the direction of shape distortion is orthogonal between the standard parallels and elsewhere; notice how areal distortion changes from compression to expansion between the parallels and elsewhere in the conformal conic.
