Exercise 01 - Moving around your map

We'll review different options to move around your map


Double clicking on a layer

By double clicking on a layer, you will: turn the layer on, make it active, and zoom to the layer extent

  1. In the sample project, double click on layer 'State' - it will zoom to the extent of the State of Iowa

You can also search for coordinates by clicking on the GPS coordinate locator, using a GPS coordinate taken from the field, or Google Earth for instance.

After you enter the coordinates, the screen will zoom in to the entered coordinates.

For this example, try entering the following coordinates:

Lat: N 42 15' 38.23"

Lon: W 93 23' 32.8"

Click on the Coordinate locator, enter the coordinates and click on 'Accept'. Your screen should look like this.
