Coursework tips


Here is the full set of icons which Goggle supply.

See Lecture 16 for an example of its use


Google Earth will display the location of a point in either decimal degrees or degrees minutes seconds - you can select which in the options.

With GoogleMaps, the lat and long appear in the URL of a place - you may have to zoom in and out to get it to appear in this format.

If your data has locations in degrees, minutes and seconds, you can convert to decimal degrees using the formula

decimal-degrees := degrees + minutes / 60 + seconds /3600

You will have to take account of the direction too. N and E are positive, S and W negative.
