Because area grows with the square of radius, so an outer ring covers more ground than an inner one of the same width. Taking the square root of a uniform draw spreads points evenly by area rather than by distance.

Because a degree of longitude spans far less ground at high latitude than at the equator. Uniform sampling in degrees therefore packs points together near the poles.

Sampling for field surveys, generating test data with realistic geography, spreading synthetic load across regions, and games that place objectives at random.
