GPS Datum 

Changing the Datum 

All GPS units are set to the World Geodetic System 84 datum by default.  This is a standard 
coordinate system used worldwide with reasonable accuracy.  The datum used by the Hexcorder Pro 
can be changed to a local datum, however this will change the GPS coordinates stored in the data, 
and they will not align with coordinates stored in WGS84. 

The GPS datum can be changed by adding a datum file to the Hexcorder Pro SD storage.    The 
datum is stored in a text file which must be named DATUM.TXT.  The datum files can be generated 
by a small Windows application that Cath-Tech has developed and is available on our website. 

Select the datum you wish to use and press the “Save to DATUM.TXT” button.  It will open a Save 
As window which you can use to navigate to the Hexcorder Pro SD storage.  The correct 
DATUM.TXT file name is automatically filled in. 

Custom datums can be generated using the program if the user has the Major Axis, Flattening value, 
and DX/DY/DZ values.
