Class OsmLatLon

java.lang.Object

de.westnordost.osmapi.map.data.OsmLatLon

All Implemented Interfaces:

LatLon, java.io.Serializable

public class OsmLatLon
extends java.lang.Object
implements LatLon, java.io.Serializable

A geo position (without height) implemented using two fixed 1E7 integers, meaning that the maximum precision is limited to 7 decimal points. Coincidentally, this is exactly the maximum precision the positions are saved in the OSM database, hence the name OsmLatLon So, this saves 8 byte per coordinate from an implementation based on doubles ;-)
