- TopoQuest
TopoQuest is a free
web mapping service built onopen source software that provides internet-basedtopographic maps for most of theUnited States .The site is one of three internet services used by
Wikipedia for providing topographic maps. It arose to prominence in May 2008 afterTopoZone through 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 ,PHP andMySQL alternative toMicrosoft 'sTerraServer-USA topographic mapviewer. [ [http://www.topoquest.com/about.php About Topoquest - topoquest.com] ]The domain was registered at
Go Daddy to 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 graphic maps available from theLibre Map Project andInternet Archive and was operating by May 2008. [ [http://www.topoquest.com/about.php About Topoquest - topoquest.com] ]Code was adapted from the
MapServer project at theUniversity of Minnesota . The viewer was made seamless by incorporatingGDAL .In addition to matching the Topozone
URL 's, the website offers free download ofGeoTIFF s, 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.
