It's not in order to store lat/long, but in order to get a better
resolution than 360x180, right ? It's a matter of choosing a resolution,
more than a number of digits.

GEOJson uses the concept of "quantization" as the number of distinct
values each ordinate can take. The format encodes the scale and offset,
right ?
