To say that this is a confusing array of products would be an understatement!īaseCamp processes the licensing data and therefore must be used to both receive the images/maps and upload them to the GPS. Note that the maps and images are locked to a particular GPS device and cannot be transferred from one to another. When a subscription runs out, the images and maps already on the GPS remain usable but no further uploads from Basecamp are permitted until the subscription is renewed. A UK map is based on the Ordnance Survey 1:25,000 series is available separately and provides 3,000km 2 of coverage for a single subscription. The maximum area that can be downloaded as part of a single subscription is 600km 2. BirdsEye Select delivers data directly derived from the most popular European paper maps and covers Germany, France, Great Britain and the Republic of Ireland, as well as the Kompass branded maps for Austria, the Eastern Alps (Southern Germany/Northern Italy) and Switzerland.The coverage area is the entire U.S and Canada, south of 68 degrees latitude. BirdsEye TOPO delivers high-quality 1:24,000 USGS and 1:50,000 NRC maps that offer a view of the terrain including points of interest such as car parks, camping areas, trails and water sources.BirdsEye Satellite Imagery delivers an unlimited number of worldwide high definition satellite images.This takes three forms – BirdsEye Satellite Imagery, BirdsEye TOPO and BirdsEye Select, each of which costs about £22 per year per GPS device: Those particularly interested in using high-resolution satellite imagery and/or detailed proprietary raster maps as overlays might like to access the Garmin BirdsEye subscription service. These maps are georeferenced and tiled KMZ files more often than not obtained by scanning a paper map to produce a JPG image, geolocating it using Google Earth, exporting it as a KMZ and then tiling it using software such as KMZFactory.Ī user wishing to use aerial images as a backdrop for a GPS display can adopt much the same process as that employed to produce custom maps – the GPS is not able to recognise the difference between maps and aerial images as they are both raster scans. Using Garmin GPS units with Custom MapsīaseCamp and contemporary Garmin devices allow the display of custom raster maps/images which reside in the \Garmin\CustomMaps folder located on the GPS (main memory or SD card).
