On August 29, 2008, Maptech, inc., makers of navigation products for marine, land, and aerial use officially shut its doors after nearly 20 years of business. This has been a very hard and stressful time for its 75+ employees. We worked together as a family for many years and we were all saddened to see it close.
Fortunately, nearly all of Maptech's products (and many of its employees) have found new homes. While I may not be able to respond to your specific email request, please allow me to direct you to the folks that may be able to assist you.
Maptech's Land Navigation division, including products such as Terrain Navigator and Terrain Navigator Pro, as well as the popular online Mapserver, has been purchased by mytopo.com. We have also reached agreement to continue to host the historical USGS map collection. For technical support for these products, please email us at 'firstname.lastname@example.org' or call 406-294-9994. Sales inquiries may be directed to 800-627-7236.
