No need to guess where the data comes from, all you need to do is look at the product page. I have the Garmin Northeast 24k Topo and it looks good. I'm a little surprised by this claim about the 24k topo maps. The maps that Garmin sells on SD cards can be used in any GPS but you must use them on the original SD card, they will not work if copied to another card. So if you sell or lose your GPS, your map will be useless. The downloadable Garmin topo maps can only be used on the original GPS for which they were purchased. Garmin's maps are copy protected which severely restricts their use. This could be an advantage for people who are not technically inclined. Garmin will offer tech support for their maps and will 'hold your hand' if you have problems installing or using the map. In most cases, maps from different authors at GPSFileDepot will have some issues where they meet. Garmin's maps can work seamlessly with each other across state lines. Maps on this site are not going to have that level of detail. Garmin's maps also contain a rich database of POI's - things like gas stations, restaurants, stores, etc. Almost none of the maps at GPSFileDepot are capable of this, they cannot calculate routes. This means they can provide turn by turn routing instructions to reach a destination. Garmin's 24k maps contain routable roads based on the same data from HERE that is used in their City Navigator products. This feature is only available on Garmin products, there are no third party tools for using DEM in a map. Garmin's 24k topo maps include DEM (Digital Elevation Model) data in their proprietary format that provides 3d shaded terrain. So you will see a big variation in the maps on this site.īut you could made some generalizations. GPSFileDepot is just an archive of maps that are made by many different people with different skill levels and interests. There really isn't an answer to this question because there's no such thing as 'GPSFileDepot maps'.
