TopoQuest is a free
web mappingservice built on open sourcesoftware that provides internet-based topographic mapsfor most of the United States.
The site is one of three internet services used by
Wikipediafor providing topographic maps. It arose to prominence in May 2008 after TopoZonethrough its new trails.com owners required payment for access to its maps. TopoQuest map links are the same as Topozone's except for the difference in the domain.
It is operated by Ryan Niemi in
Klamath Falls, Oregon.
Niemi first experimented with a mapping program in July 2001 as a
Linux, PHPand MySQLalternative to Microsoft's TerraServer-USAtopographic mapviewer. [ [http://www.topoquest.com/about.php About Topoquest - topoquest.com] ]
The domain was registered at
Go Daddyto Sunset Dynamics on August 10, 2004. [http://www.who.is/whois-com/ip-address/topoquest.com/ whois lookup record] ]
However Niemi did not aggressively develop the website because of the success of Topozone.
After Topozone started the for pay business model in April 8, 2008, Niemi made updates to get the website to match the Topozone URL methodolgy for viewing 1:24K
USGS Digital raster graphicmaps available from the Libre Map Projectand Internet Archiveand was operating by May 2008. [ [http://www.topoquest.com/about.php About Topoquest - topoquest.com] ]
Code was adapted from the
MapServerproject at the University of Minnesota. The viewer was made seamless by incorporating GDAL.
In addition to matching the Topozone
URL's, the website offers free download of GeoTIFFs, which Topozone had only offered for a premium.
Niemi is working on a Canadian topographic map viewer which he hopes to unveil in July 2008.
