Location Identification Navigation Unit

Guiding Question Can you identify your location using: Can you identify your location using:  Triangulation?  GPS?  Aerial Photography?

Main Ideas Students will identify and verify their location on a map by triangulating with a compass, ruler, and quadrangle, by using a GPS, and by using aerial photography found on Google Earth or Erdas Viewfinder.

Instructions Triangulation: 1. Students work in pairs. Each pair is given a local quadrangle, a compass, ruler, and a green pen. Although triangulation will have been discussed in the classroom, they will also be given the “Brunton” directions seen below.

Triangulation

Instructions Calculating Distance 2. Students will select one of the reference points used to triangulate and their location point determined in #1 and calculate the linear distance in meters.

Instructions Conversions 3. Students will convert their metric length to feet.

Instructions GPS Use 4. Students will find their location using a GPS.

Instructions Aerial Photography 5. Students will find their location using an aerial photography software system (Google Earth, MapTech, Erdas Viewfinder, etc.)

Evaluation Criteria On-line Quiz On-line Quiz 1.Identify the latitude-longitude and UTM coordinates of two points designated on a quadrangle using a UTM measuring tool. 2.Calculate the distance between the two points in meters. 3.Convert the metric length between the two points to feet. 4.Locate the position on a computer using aerial photography.
