You may have to use specific settings for your device. To Send Route Points Use the following steps to send route points to your device. The following table describes the correlation between data zoom levels in your DeLorme application and the scale bars on the device.ĭata Zoom Level Scale Bar Label km/m mi/ft NM/ft NM/m 1 1000km 500mi 500NM 500NM 2 500km 250mi 250NM 250NM 3 250km 125mi 125NM 125NM 4 125km 64mi 64NM 64NM 5 64km 32mi 32NM 32NM 6 32km 16mi 16NM 16NM 7 16km 8mi 8NM 8NM 8 8km 4mi 4NM 4NM 9 4km 2mi 2NM 2NM 10 2km 1mi 1NM 1NM 11 1km 0.5mi 0.5NM 0.5NM 12 400m 0.25mi 0.25NM 0.25NM 13 200m 640ft 640ft 200m 14 100m 320ft 320ft 100m 15 50m 160ft 160ft 50m 16 25m 80ft 80ft 25m 17 12m 40ft 40ft 12m Sending Route Information Third-party GPS Using Third-party GPS Devices DeLorme Topo North America Help If you have a compatible GPSor athletic device, you can use the Exchange Wizard to send route points or route directions to your device. The Earthmate PN-Series GPS device uses a scale bar, based on the measurement units chosen in Device Setup. In DeLorme Topo North America, scale is represented as a data zoom level (1-17). Grid Size 1.5 degree 30 minute 5 minute 1 minute 12 second 206 Factor # of Grids 9 x 30 minute 36 x 5 minute 25 x 1 minute 25 x 12 second # of Grids # of Grids # of Grids 1 N/A N/A N/A 4-20 9 1 N/A N/A 6-20 324 36 1 N/A 8-20 8,100 900 25 1 11-20 N/A 202,500 22,500 625 25 13-20 Data Zoom Level/Scale Bar Translation Display Range Your DeLorme application and your Earthmate PN-Series GPS device use different methods for representing the map's scale. A 5 minute grid = 25 1 minute grids or 625 12 second grids. A 30 minute grid = 36 5 minute grids, 900 1 minute grids, or 22,500 12 second grids. 60 seconds = 1 minute 60 minutes = 1 degree A 1.5 degree grid = 9 30 minute grids, 324 5 minute grids, 8,100 1 minute grids, or 202,500 12 second grids. This is because the grid system is based on the latitude/longitude coordinate system. A grid of the same size gets progressively larger in coverage (square area) the closer it is to the equator.
