Features and Benefits



Overland Navigator is field friendly mapping software for Windows that has been specifically designed for easy operation in harsh conditions.  The high contrast user interface is easy to see under bright sunlight.  Large touchscreen friendly buttons are easy to use even with gloves on.  Complete keyboard control makes it a breeze to use on traditional laptops / netbooks without using any mouse input at all.  Features are designed so that tasks can be completed with the least number of operations.  Menus automatically hide for maximum map visibility.  Everything about Overland Navigator is designed to be simple and easy to use in the field.


Our customers run Overland Navigator on a wide variety of hardware.  Traditional laptops, Tablet computers, Ultra Mobile PCs (UMPC), Net-books, Carputers, Auto PCs, ruggedized hardware, touchscreen capable, pen capable, sunlight visible screens, etc.  Overland Navigator takes advantage of the unique characteristics of each of these devices and works well on all of them.

Map Packs

Overland Navigator USGS Topographic Map-Packs and Satellite Imagery Map-Packs are available for a variety of states and regions.  Additional Map-Packs are being added all the time.

The Map-Packs are pre-packaged to work perfectly with Overland Navigator.  The maps/imagery have been compressed to occupy 5-600% less space than traditional scans of USGS Topographic Maps (DRGs).  They have been indexed, so that Overland Navigator can present them as one seamless map without collars (white margin around map w/ legend).  They include a Windows installer that makes installation and configuration a snap. 

You never have to manually load a map.  Overland Navigator automatically tiles maps and imagery so they appear as one seamless map or image.  As you zoom in, the software automatically loads maps with more detail.  As you zoom out, the software automatically switches to maps with less detail and eventually switches to satellite imagery. 

** Map-Packs are sold separately from the Overland Navigator Software.


The power button exits the program, writes any recorded GPS tracks to disk, and saves your current state.  For example, if you are recording a track on exit, Overland Navigator will resume track recording when the application restarts.

The Mode, last known position, zoom level, etc will also be recorded.

“GPS Mode” automatically centers the map at the location being reported by the GPS receiver. The map will automatically re-center anytime the GPS position gets close to the edge of the map. While in “GPS Mode” you can still pan, zoom-in/out, etc but the map will automatically be re-centered on the GPS position after 10 seconds with no map interaction.

If the GPS isn’t connected for some reason, pressing this button will cause Overland Navigator to attempt to connect. If the GPS connection fails, a message will be displayed letting you know.

While in "GPS Mode" the menus will automatically hide so the entire map can be seen.  Touching the screen, moving the mouse, or pressing a key will cause them to display again.

When in "Pan Mode" the map is centered by the user instead of automatically positioning it using the GPS. The map is positioned by touching/clicking with a mouse, pen, or finger or using the arrow keys on your keyboard. To center the map at a specific location simply “click” or “touch” that location on the map. Alternately you can “click and drag” the map to pan an entire screen at a time. The GPS will remain active, and your position will continue to be displayed as you pan the map, zoom in/out, and otherwise explore the map. You will know the mode is selected when its’ button is highlighted.

The map scale can be zoomed in or out via the Map Level toolbar. The “+” causes the map to be zoomed in, and the “-” causes the map to be zoomed out. The maps will automatically switch to the maps most appropriate for the current scale. For example, a typical user with a USGS Topographic State Map Pack installed and the True Marble Satellite imagery installed will see the maps change through 1:24k, 1:100k, and 1:250k USGS Topographic maps and then change to the True Marble Satellite imagery as they zoom further and further out.

GPS receiver accuracy, location, altitude, and fix quality information are all presented via the user interface. If the GPS is physically connected but the position and/or heading are unknown a red X will be shown.  The red X can also be shown if satellite reception is temporarily lost.

When the position and heading are accurately known, a triangle will be displayed at the current GPS position. The triangle will point in the direction the GPS indicates it is traveling.

The location and altitude as reported by the GPS are displayed at the bottom of the screen.

The “Record Waypoint” button allows you to mark your current GPS location with a symbol. This is a useful way to mark a point of interest (POI). For example, if you are traveling around and notice an interesting hiking trail you can record a “Hiker” symbol. Later, when you return to the area you’ll be able to quickly find your way back to the trail.

The symbol picker scrolls through the symbols by flicking your finger anywhere in the window.  This motion can be done with gloves on and is much easier than trying to use a traditional windows scrollbar as you bounce down a gravel road.

The “Record Track” button allows you to record the path that the GPS is traveling. Press Record to begin recording the track and the button will change to a “Pause” button that is active (blue highlight). Press the “Pause” button to stop recording the track.

When recording a track, it will be displayed as a semi-transparent grey line.

If you insert a thumb drive, media card, CDROM, DVD, or other removable media any GPX tracks will be displayed automatically.  This "zero-click" functionality makes loading GPX tracks in the field extremely easy.

Overland Navigator can display the contents of multiple GPS eXchange (GPX) track log files at the same time. These files can be located in your “Track Directory” or on a removable media device.

The files can be from any source including but not limited to those recorded with Overland Navigator, recorded with another GPS, created with a mouse in desktop mapping software, obtained from a friend via email, or downloaded from the Internet.

Everything in Overland Navigator can be controlled with a keyboard.  This makes Overland Navigator a snap to use with a laptop or netbook that doesn't have a touchscreen. 

The keybindings are setup by the user, so you can set it up anyway you want.  For example, F1 could record a campsite waypoint, PAGE UP could zoom in, and the arrow keys could pan the map.  You can set it up in anyway that works for you, but it comes pre-configured with a reasonable set of defaults.


Windows Message and Automation API - Can be used to completely control Overland Navigator with 3rd party input devices or your software.

Coupled with Girder you can control Overland Navigator with other software, infrared remotes, or other input devices such as the Space Navigator or a Powermate.
