Map Screenshots
Screenshots of all the different types of maps that can currently go on the PN-xx (shown in alphabetical order). Please keep in mind that not all imagery has been created equal.
- It has always been good practice to 'cut' a small map with the zoom levels set to the Max/Min of the area that you want to see prior to 'cutting' larger maps from. Doing it this way will allow you to see how the map will look on your PN-40 and let you decide at which zoom levels you are going to 'cut' your map at.
- The higher the zoom level you 'cut' a map package, the larger the file will be.
3DTQ
3DTQ (3D Topo Quad - USGS 7.5-Minute Quadrangles). These maps are available either through Netlink or an available DVD (state sets) from DeLorme. The screenshots below were 'cut' with a zoom level from 10-15.
CDOQQ
Color Digital Ortho Quarter Quads are available from DeLorme's Netlink via Topo USA. This data was 'cut' using Zoom Levels 11-16.
Custom Rasters
These screenshots were 'cut' using XMap and .sid/.tif files found freely throughout the web. This imagery happens to be a .sid file. The shots below are from Zoom Levels 10-16.
DOQQ
Digital Ortho Quarter Quads (black & white) are available from DeLorme's Netlink via Topo USA. This shot was 'cut' with a Zoom Level of 10-17.
Hi-Res 133
Hi resolution Imagery downloaded from Netlink. The default 'cut' level was zoom levels 13-17. The area is near Harrisburg, PA.
ImageReg
This screenshot is a PDF of snowmobile maps. The process was done using the ImageReg in XMap. The map was 'cut' with a zoom level from 11-14 to exchange to the PN-40.
NOAA
National Oceanic and Atmospheric Administration Nautical Charts. The shots below are Harbor Charts.
SAT10
SAT 10 is 10-meter resolution natural color satellite imagery. This Map Package was 'cut' using Zoom Levels 6-12.
Topo USA Data
Topo USA Data is provided to with your PN-xx (this is the CD in the jewel case and it contains the Topo USA Program and mapping data). The PN-xx comes with a World Base Map that is visible from Zoom Levels 1-12 (500mi - 0.25mi). The screenshots below represent the entire Zoom Range. This particular map was 'cut' from Topo USA using Zoom Levels 10-17 and used High Contour Values (set up using the Options Tab in Topo USA).
