A GPS track on google maps?

Welcome to the fun Nesty!

Yes, the first step is to get a GPS device to record your session. The best approved one for GPS-Team Challenge at the moment is the Locosys GW-52, or if you can get a used one, a GT-31.

But almost any GPS file, preferably written at a minimum 1 second intervals, will be able to be converted into a trackmap on a Google earth background in a number of different ways.

Like this:



This one was created using a free web based program called GPS-Visualiser.

Here: www.gpsvisualizer.com/map_input?form=google

Here is how I input the data:



Note that I have only made changes to some inputs.

1. Give it a name if you like
2. select 'Google aerial/satellite imagery' from the drop down menu
3. Insert 10 in the time offset space for Australian East coast time.
4. Select 'Nautical' in the Units drop down menu for Knots.
5. Select 100% in the 'Track Opacity' drop down menu.
6. Type 1mm in the Line Width window - this seems to work best.
7. In the 'colourise by' drop down menu select 'speed'

Those are the only ones I change.

8. Then on the right hit the 'choose file' button and select the GPS file you want to map from your computer file system (normally one of these types: .sbn .sbp .gpx. but there are many other GPS files types depending on the particular GPS it comes from)

9. Next hit the Draw the Map button and wait a few seconds to a minute or so.

A new tab will open in your browser like this:



You can either take a screen print of this image or download it from the green highlighted links at the top.

Note that there is a drop down menu in the top of the image that allows you to open your tracks over different types of maps and images. It can be quite interesting to play with.

Using KA72

Another easy way to view your tracks on a sat map is to upload your tracks to www.ka72.com where you can also see your speed and distance analysis and post your results to GPS-Teamchallenge.

Hope this helps.

Join KA72 and start posting. There is even an icon on 'my tracks' which takes you to a google Earth map.

Very simple and plenty of help here too
