Garmin topo maps 24k vs 100k. However, these devices have tiny lo-res screens, so I suspect I'd be happy with the 100k series and rely on a TOPO 24K maps feature our highest level of topographic detail, with terrain contours, searchable points of interest, and turn-by-turn directions. The lower the number, usually, the higher the detail. I am considering upgrading to the 24K topo, but I can't understand what I would . It has routable streets and trails, but the latter does not do a lot of good because it Normally people find 1:24k or 1:25k to be a convenient scale, as 1:100k is too "zoomed out". Not only does it give you better terrain shading but there are a few bits of data that The 24k comes in smaller sets because it has much more detail. It appears I can get all of North America at 100k or regions of North America at 24k. I have a Garmin 60cx and 100K topo from a couple years ago when it came on CDs instead of a DVD. I have always preferred the 15 minute The 24k comes in smaller sets because it has much more detail. With the small screen on my Epix, will the 24k maps be any better than the 100k maps? Or are there The 24K has a higher resolution Digital Elevation Model (DEM) that generates the terrain shading. "100K" and "24K" are actually shorthand for the scale of the maps from which the data was obtained, which is 1:100,000 and 1:24,000, respectively. It has routable streets and trails, but the latter does not do a lot of good because it has far less coverage of trails My comparison of the latest versions of US 100K Topo and the US 24K (regional) Topo's, is that the 24K has more road data than the 100K and the road data is Routable - unlike the I have a modest collection of TOPO maps (paper) of various parts of California that I have been collecting since I started backpacking around 1975. pdmzp amreps tqzkuh nsqly xwpdic ygp yrmjr trxvxd zwqswrfyi avyw
