Constants
CODE_ALPHABET = "23456789CFGHJMPQRVWX"
The character set used to encode coordinates.
DECODE = [nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, -1, nil, nil, nil, nil, -1, nil, 0, 1, 2, 3, 4, 5, 6, 7, nil, nil, nil, nil, nil, nil, nil, nil, nil, 8, nil, nil, 9, 10, 11, nil, 12, nil, nil, 13, nil, nil, 14, 15, 16, nil, nil, nil, 17, 18, 19, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, 8, nil, nil, 9, 10, 11, nil, 12, nil, nil, 13, nil, nil, 14, 15, 16, nil, nil, nil, 17, 18, 19]
ASCII lookup table.
LAT_GRID_PRECISION = 5_i64 ** (MAX_CODE_LENGTH - PAIR_CODE_LENGTH)
Precision of the latitude grid.
LNG_GRID_PRECISION = 4_i64 ** (MAX_CODE_LENGTH - PAIR_CODE_LENGTH)
Precision of the longitude grid.
MAX_CODE_LENGTH = 15
Maximum number of digits to process in a plus code.
PADDING = "0"
The character used to pad a code
PAIR_CODE_LENGTH = 10_i64
Maximum code length using lat/lng pair encoding. The area of such a code is approximately 13x13 meters (at the equator), and should be suitable for identifying buildings. This excludes prefix and separator characters.
PAIR_CODE_PRECISION = 8000_i64
Inverse of the precision of the pair code section.
SEPARATOR = "+"
A separator used to separate the code into two parts.
SEPARATOR_POSITION = 8
The max number of characters can be placed before the separator.
