Fields
Map Name
- The name you want to give to this map.
Map Datum
-
The actual datum of the map. To be fully correct this must be the datum of the
positions of the points used to calibrate the map. Since these points are usually taken from the map
itself then the MapDatum should be the actual datum of the map you are calibrating. If the map
datum is not specified correctly then any positions obtained from the GPS and plotted on the map
will be in error.
Mag Var
- The Magnetic Variation, this may be given on the border of the map. If not specified
OziExplorer will calculate the magnetic Variation when it is required.
Map Projection
Selecting the Map Projection or Grid
These instructions only apply to the registered version of OziExplorer. The unregistered version is
limited to a 2 point calibration in a projection called Latitude/Longitude.
The
Map Projection
to choose depends on the projection and/or primary Grid system used by the
map. This is usually stated somewhere on the map. Most (but not all) topographic maps used for
general purpose mapping are in the
Transverse Mercator
projection and if you do not know the
projection this is a good one to start with. Maps for marine use are usually in the
Mercator
projection.
The combo box labeled
Map Projection
gives a choice of various Map projections or Grid systems
supported by OziExplorer.
If you are using a map which is laid out in a standard Grid system such as UTM (Universal
Transverse Mercator), BNG (British National Grid) etc simply choose the grid from the list, all the
parameters required are known by the software.
