    • 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 .
