see the table above, whether you will require a default.ozproj file for your DEM

The default.ozproj file is read as each folder is scanned, all the DEM files in the same folder are

assumed to be using the parameters specified in the default.ozproj file. If you have DEM's which

use different grids or datums then these must be put in their own folder with a default.ozproj file

setup with the correct parameters. OziExplorer scans all sub

folders attached to the folder

configured in Elevation Configuration so all the DEM's will be found.

Example Projection File

Below is an example of a default.ozproj file

this file is setup for the New Zealand Grid and Datum.

These are the lines in the file which control the DEM -

not all these parameters are required in every

instance, the parameters which are not required can be left out of the file. Read the instructions

contained in the example default.ozproj file below.

delta_x

- used to offset the height data in the x direction (east -

- south)

These lines are only needed for certain grids and projections

lon_origin

lat1

lat2

false_easting

false_northing
