TopoFusion

TopoFusion is a fully featured GPS Mapping program. It seamlessly displays imagery from Terraserver and the OnEarth Server. Maps are downloaded on demand (as the user pans or zooms around the map) and cached on the user's hard drive for faster (and offline) storage.

The main function of TopoFusion is to quickly display, scroll and zoom about these maps, while overlaying GPS and GIS data on top of them. To enable download of Maps all you need is an active internet connection. Opening the program will default to a world view and begin downloading satellite maps to fill the screen. Opening a GPX (GPS eXchange File) via the file menu or the browser at the bottom of the screen will move the map to display the GPX file entirely. The mouse can be used to pan about the map causing more tiles to be downloaded. Zooming in and out can be accomplished using the mouse wheel (or the plus and minus keys). As the zoom scale is changed different resolutions of maps will be downloaded.

Minimalist Instructions

Download and install the software from http://www.topofusion.com/TopoFusion-Demo-DWD-3.41.exe. This will also install all of the leg files for both the 100K Relay and 50K/50M Ultra races. (Note: this demo version is restricted to southern Lower MI and a bit of northern IN/OH.)

Run TopoFusion: Start > All Programs > TopoFusion > Topofusion. Note that the documentation is at Start > All Programs > TopoFusion > TopoFusion Manual.

In the lower left panel, navigate the folder structure to "Dances with Dirt Course Files", then to "relay" or "ultra" by double-clicking the folder name. The files in that directory will be displayed in adjacent panel.

Once you've selected which race to load, click "Add All;" this will load the leg files into the lower right panel - the Active File List - and they will appear on the map.

Once a leg has been loaded into the Active File List, double-clicking a leg name will highlight the leg and center the map on that leg.

The type of map being displayed and the map resolution is controlled via the drop-down in the upper right.
