A program called Google Earth can be downloaded from Google. Google Earth can be used in a number of ways:
You can find the location of your photo points and it will give you the coordinates that can then be recorded.
One of the features on Google Earth is place marks. This should only be used as an additional method for recording places as the information can be easily lost. Remember to save the information by going to File > Save > Save Place as. Keep the saved file with the images of your photo points.
A big thank you to all our kind sponsors, without you our work would not be possible.
