Data Zoom Level/Scale Bar Translation
Your DeLorme application and your Earthmate PN-Series GPS device use different
methods for representing the map's scale. In XMap, scale is represented as a data
zoom level (1-19). The Earthmate PN-Series GPS device uses a scale bar, based on
the measurement units chosen in Device Setup.
The following table describes the correlation between data zoom levels in your
DeLorme application and the scale bars on the device.
