Selecting the Map Datum
When using the eXplorist in conjunction with a map or chart, you should make sure that the
map datum in the eXplorist matches the map datum that the map or chart uses. This can
usually be found in the legend block on the map or chart. The default map datum for the
eXplorist is WGS84 and should be used when in doubt.
