| Summary : represents an approximate global position by a single number
|
Description :
It is sometimes useful to condense the information present in a latitude
and longitude into a single number (for example, when storing the position
within a database). This module provides methods for this conversion. By
default, the precision of the position is set at 32 bits (roughly
Assuming the surface area of the earth is 5.1 x 10^8 sq km, the area
represented by the single number at each precision is as follows:
0.12 sq km at 32 bits
0.24 sq km at 31 bits
0.47 sq km at 30 bits
0.95 sq km at 29 bits
and so on (5.1E8 / 2^precision)
These areas are constant across all latitudes and longitudes.
Thus, if you want to be fairly precise about positions, you can store
fairly large numbers, whereas if you want to be fairly imprecise, you can
use small numbers.
