location based services

The Marengo GPS Route Planner is a free service to allow you to use Google Maps to define a route (specifically a set of waypoints) which you can upload to your GPS. It has been designed primarily for use with the Garmin Edge (TM) series of GPS-enabled bicycle computers, but because it is built around open specifications, it may be of use on many other GPS devices. See here for an introduction to why this site was built.
Planning Your RouteName Your RouteWhen you first start the Marengo GPS Route Planner, the text box entitled "Route Name" is highlighted. Enter a name of up to 10 characters in here to identify the route on your GPS once it's been uploaded. Find Your Start PointNow find your starting point. Use the slider on the left side of the map to zoom in and out, and drap the map around to change the area you are looking at. You can use the overview map in the bottom right hand corner to move further more quickly. Set a WaypointOnce you've located your start point, simply click on the map! Be as accurate as you can - GPS units these days are very accurate, so position your waypoints with care to ensure that the GPS warns you at the right moment. You may find that switching to Satellite view on the main map may help with your accuracy. Many areas don't have high-resolution satellite images in Google maps yet, so this may or may not be of use to you. Note that, once you've placed a waypoint marker on the map, you can drag it around, so you may find it useful to place markers roughly to start with, then zoom in and place each one more accurately
