About OziExplorer

OziExplorer (OE) is a program written by Australian Des Newman and his wife Lorraine. It closes the gap between a scanned map and the digital output of your GPS. What it basically does is putting the GPS output in a graphical form so you can look at a map (or picture) to see exactly where you are. It displays your present position, the direction you are heading and the way you came from. You can also add comments and events without altering the map. Pictures can also be included. 
Des initially made this for his own 4x4 activities but it proved very useful for others too. Here his own comments: "The software was developed to allow me to set up my 4 wheel drive trips. Before the trip I scan in the relevant map if I have not already done so. I then sit down and work out where I am going, and using OziExplorer, position waypoints on all the road and track intersections and towns etc. Add in Map Features and Map Comments where appropriate. Use events to mark the position of the roads and tracks. I save all these to files as necessary. I add waypoints and events to more than cover the region I expect to visit to allow for change of plans. When I am happy with the map I then send the waypoints and events to the GPS and print the map and waypoint list."
