FOREST Navigational Tools
Map & Compass
The proper use of a map and compass is essential in many natural resource professions. They are important not just for knowing where you are and where you are going, but for representing field measurements on maps, and for translating map measurements into the field.

FOREST's compass exercises are simulations of five essential map and compass skills. These exercises build on each other, so we suggest starting with the first exercise and progressing through them in order.

  • Magnetic Declination
    In order to use your compass accurately, you will need to find an important feature in the legend of topographic map-- the magnetic declination for your area.

  • Orient a Map
    Matching the orientation of the map to the features on the ground will lead to successful navigation by giving you a better understanding of where you are in relation to where you want to go. It also can be especially helpful when you are trying to identify prominent features from a viewpoint.

  • Take a Bearing
    Taking a bearing from a map helps you translate a map measurement into the field by determining the direction of travel between two points.

  • Project a Bearing
    Projecting a bearing on a map helps you represent field measurements on a map by showing a line that represents a given course.

  • Triangulate a Position
    Triangulating a position involves using two fixed points to determine the position of an unknown third point.

GPS stands for Global Positioning System. By using a global positioning system, you can calculate your location anywhere on the earth.

GPS is based on a network of satellites and a portable receiver used to determine horizontal and vertical locations on the Earth and to record or display those positions in a coordinate system selected by the user. The GPS satellites are available worldwide and operate 24 hours a day, every day of the year.

  • GPSMap76 Simulator
    Using the Garmin GPSMap 76 that you'll use in the field, navigate through several different tasks. The list of tasks includes: turning the unit on, checking battery life, marking a waypoint, creating a route, setting up a track log, and more. These exercises are intended to reinforce your knowledge of how to use the Garmin GPSMap76.
