Garmin Colorado Maps

I noticed in this review of the Colorado series at GPS Magazine, that the Garmin Colorado 300 and 400t have a "Digital Elevation Model" world base map, while the Garmin Colorado 400i and 400c have a "Satellite" world base map.

 

What are the differences between a "Digital Elevation Model" world base map and a "Satellite" world base map?

 

Thanks!

Then you better go buy a Delorme PN-20. I've been using satellite maps (color or B&W) for over 6 months. Also USGS Topographic maps (Quads) with lots of detail you won't see many other topos. More info about maps on GPS units. Outside the US is still an issue (not the GPS hardware side, but the countries involved).

You can get down to street detail anywhere in the USA. Where I would like would be a worldwide street level and topo like the hybrid Google maps, maybe Google can do it, just wishful thinking.

Bushnell is a step in the right direction for the "perfect" GPSr, but I think they will tackle the worldwide meshing of Google type aerials or Sat views pretty soon. thanks for the maps website BTW

Which DEM?

The 1:250K scale,

or the 1:100K scale,

or the 1:25/24K scale.

Or perhaps the DLG not DEM data?

I thought that there was a fundamental difference in how Garmin makes their topo vs how Magellan makes theirs. Magellan uses a DEM, I don't know what it is that Garmin uses but know it has some better capabilities.

 

All are available for free from USGS if you have trillions of bits of storage.
