Specifications

It is our intention to support other formats where possible and also to support
more map projections and coordinate grids. For us to support a particular
format we would need a couple of example DEM files, information on the
projection/grid used for the data and the specifications for the format of the
dem file.
See the bottom of this page for details on making your own "default.ozproj" files.
