kGMSEquatorProjectedMeter

extern const double kGMSEquatorProjectedMeter

kGMSEquatorProjectedMeter may be useful when specifying lengths for segment in “projected” units. The value of kGMSEquatorProjectedMeter, 1/(pi * EarthRadius), represents the length of one meter at the equator in projected units. For example to specify a projected length that corresponds to 100km at the equator use 100000 * kGMSEquatorProjectedMeter. See [GMSPath segmentsForLength:kind:], [GMSPath lengthOfKind:] and kGMSLengthProjected.
