Static webStatic webGenerated using TypeDoc
Units utils contains methods to convert data between representations.
Multiple methods are used to reprent world coordinates based on the type of data being presented.
WGS84 is the most commonly used representation with (latitude, longitude, altitude).
EPSG:900913 is used for planar coordinates in (X, Y, Z)
