Geodetic Coordinate Calculations

This page is used to convert geodetic coordinates from (or to) a geoditic datum to (or from) the reference geodetic datum WGS84.

You need to specify which geodetic datum to use.

If you specify the latitude, longitude and TVD in the reference datum, then after clicking the calculate button, you will get the latitude, longitude and TVD in the WGS84.

If you specify the latitude, longitude and TVD in the WGS84 datum, then after clicking the calculate button, you will get the latitude, longitude and TVD in the reference datum.

If in addition, you have specified the octree depth level, you will also get the octree code, i.e., a high and low unsigned long integer

You can also, enter the octree depth level and codes, and you will get the latitude, longitude and TVD of the center of the provided octree

If several possibilities exist, the order of priority is: conversion from the reference datum, conversion from WGS84, consersion from octree code.
