Experience with TopoZone maps?

I'm considering subscribing to Topozone to aid in planning a couple trips I'd like to take this
summer in the NorthWest (Northern California, Oregon, and Washington).

Their free online interface looks promising but of course the resolution is not very good.
The sample map they provide is of an area I'm not familiar with, so I really can't tell how
useful it is.

Does anyone here have any real-world experience with the accuracy and usefulness of their maps,
particularly in rural areas? Are the higher-resolution versions sufficiently readable to be useful
in planning routes?

I find their maps useful and spare me the problem of going a half mile down the street here to
the US Geological Survey office from whose maps these are made. A typical examle is our local
Mt Hamilton:

Or Mount Wshingtom NH where the 34% grade RR is apparent from its maximum grade course,
perpendicular to all contours. Mr. Marsh wasn't kidding when he chose this route, the first cogwheel
RR in the world and steepest vertical engagement rack ever.

I like using Topozone for a quick look at an area, but if I want a high resolution printed map, the
National Geographic series is very nice:

If you don't want to buy the software, there are kiosks at REI that let you print out custom maps on
waterproof paper.

But if you're planning a road route and want quickly to know distance and elevation, DeLorme's
TopoUSA is more useful:

It overestimates vertical climb somewhat, and some of the road information is incorrect, but it's a
quick and easy estimation tool.

On TOPOZONE.COM you can get 1:25,000 scale, which is pretty dang good.. for free!. I've used these
maps on several middle of nowhere hiking trips in VA, WV, and California. You can change the scale
and size of the map you want for free. Then laminate the printed map and you're set. The National
Geographic maps look like the exact same maps.

Thanks for the information and links. I've looked at the software packages, before, but they weren't
available for my computer. It looks like National Geographic's Regional series is now available,
though; I'm ordering the Oregon version.

Hopefully that will give me what I need, otherwise I'll go ahead and subscribe to Topozone.

Thanks, Sam

All of these maps are based on USGS (a federal agency) data. Some of the USGS data is decades out of
date. Some of the 3rd party companies add their own data on top of the USGS base, usually to add
modern roads, trails, etc.

Yep, I compared my maps from REI with the Topozone.com maps and noticed
+ or - a few marked trails. It would be great to find some with old railroad grades marked also. The
trails we were on crossed several of these, which seemed perfect for cross country skis.

This is typical of the USGS maps I have seen and the RR ROW is obvious both through text n the map
and that it follows contour lines. The RR is the road through the red cursor in the center of the
map. I have ridden on these dirt roads on a ride from Sonora over Tioga Pass.

Cool! There are alot of grades on the east coast that are not marked. You can even see them
winding up the mtns when all the leaves fall off. We actually followed and mapped one on our GPS
in western VA and are going back next year to ski it. I saw a strange local club on the news
that's going out now and mapping old roads and routes dating from the 1700's that have long since
succumb to the forests. They date them by looking at how old the trees are that having grown in
the middle of the trials.

It overestimates vertical climb somewhat, and some of the road information is incorrect, but it's
a quick and easy estimation tool.

Somewhat is a bit of an understatement. I find that on most of the hills around where we both live
that DeLorme can overestimate the climb by 30-50%. I, too, find it useful for routing and getting a
general impression of the profile of the route. But one should not look at the actual numbers as
they are too over-inflated. It is a problem caused by their vector orientation; roads are series of
vectors that are too long to closely fit winding roads. The 3D preview is cool. Routing between end
points is a bit sketchy at times, so one needs to put in a lot of 'via' points to make it actually
follow the road. For fun, do a start route at the junction of Portola Valley Rd and Old La Honda, a
finish route at Skyline and Morshead Rd (what they call the top of Old La Honda ..). Then have it
calculate route via road. They seem to take every side road and include very little of Old La Honda.
Amusing. I use DeLorme to get a general idea and to lay out routes for the GPS; for detailed info I
use the Nat. Geo. stuff.
