I used to be a heavy Topozone user, but in early April, Topozone was bought out by Trails.com and
ceased to provide useful topographic map viewing functionality. Argh! Time to find
a Topozone alternative. So, seeing that
I have a heavy background in web application development with Linux, PHP and MySQL, plus a lot
of experience in digital mapping, I decided to craft a replacement as quickly as possible to
replicate the functionality Topozone used to have.
If you have Topozone map URL's, you can quickly and easily turn them into the TopoQuest
equivalent. All you need to do is replace topozone.com with topoquest.com in the
URL, and leave everything else the same. A PHP script on our web server will
translate the Topozone URL into the TopoQuest equivalent.
For example, let's say you have this old Topozone URL on your website and need something still useable:
All you need to do is replace topozone.com in the example URL above with topoquest.com:
For a topographic map browsing browsing alternative to Topozone, you can use our
Map Viewer instead. To search for a location, landmark
or feature, you can use our Find Places search tool.
To locate a particular USGS topographic map, our Find Maps tool
is what you're after.
And, we have a few additional features Topozone never had. You can download
any of the topographic maps in DRG (GeoTIFF) form for free, for use with your own
mapping applications like USGS DLGView, Fugawi, etc..
