Anquet Maps have been building digital mapping systems since 2001. This latest version of OMN was built with the help of our customers, concentrating on usability and consistency across our apps on all platforms to allow users to learn the system once and easily move between computers without having to relearn everything. Although you have a full route editing system on your phone or tablet, having access to the same tools on your desktop computer will make your route planning much easier due to the larger screen. OMN on the desktop also contains a very powerful print engine to allow you to make map prints to carry as a backup.
