A quick and easy way to check that a file is correctly geo-referenced, is to export it to Google Earth. Google Earth is a free web based 3D mapping software (see for more information).

To complete the following steps, you will need to have Google Earth installed.

First, we will make sure you have a Google Earth export specification (KMZ); this depends on the Normal.iop file in your <Defaults and Layouts> folder.

  1. Home | Web Mapping button.

  2. Google Earth tab, select All Features.

  1. Press the Update Google Earth button – this will save a geo-referenced Google Earth file (.kmz).This also should run Google Earth and place your roads at the correct geographical position as shown in the figure below.

  1. Close Google Earth.

  2. Close the Web Mapping dialogue.

  3. File | New. Do not save the changes. Continue to the next example.
