Basemaps vs. Detailed Maps
Basemap
A basemap contains major map features like highways, railroads, cities, etc.
Magellan mapping GPS receivers have a built-in basemap. Basemaps have
sufficient detail for orienting oneself to a broad geographic area. The basemap
is displayed at higher zoom levels or when you view a geographic area for
which there is no detailed map.
Detailed Map
Detailed maps contain more map features and more specialized information
than basemaps. Detailed maps are useful when you want to work with smaller
regions, close-up. There are a wide variety of optional MapSend detailed
products available, including street maps, topographic maps, and marine
charts. Depending on locale, there are a variety of MapSend detailed map
products available. MapSend DirectRoute Europe provides detailed streets,
highways, and points of interest for France, Germany, Austria, and Switzerland.
Detailed maps and basemaps work together to provide a useful map view at
any zoom level. Uploading a detail map does not erase the built-in basemap in
the GPS receiver.
You can define and save many detailed map regions in MapSend on the PC. If
you have a SporTrak receiver, you can connect it to the PC and upload any saved
map to the receiver’s memory. If you have a Meridian with an SD card inserted,
you can connect it to the PC and upload to the card in the unit, or you can use
an SD card reader/writer to upload the map directly to the SD card.
