Land navigation is the ability to find your way around using a map and compass. It is a fundamental skill for anyone who spends time outdoors, whether you are hiking, camping, or simply exploring your local area. In this section, we will discuss the basic skills of land navigation, including map reading, orientation, and compass use.

Map Reading and Orientation

A map is a graphical representation of a particular area. It shows the location of features such as roads, rivers, mountains, and buildings. Map reading is the ability to understand and interpret the information on a map. Orientation is the process of aligning yourself with the map.

It involves understanding the relationship between your current location and the features shown on the map.

Map Symbols

Maps use a variety of symbols to represent different features. It is important to understand the meaning of these symbols before you can effectively use a map for navigation. Some common map symbols include:

  • Roads:Roads are typically shown as lines, with different widths and colors representing different types of roads.
  • Rivers:Rivers are shown as blue lines, with the width of the line representing the size of the river.
  • Mountains:Mountains are shown as brown contours, with the height of the mountain represented by the number of contour lines.
  • Buildings:Buildings are typically shown as small squares or rectangles.

Determining Grid Coordinates

Grid coordinates are a system of numbers and letters that are used to locate specific points on a map. They are essential for navigation, as they allow you to pinpoint your exact location and the location of your destination.

  • Grid Lines:Grid lines are a series of horizontal and vertical lines that are printed on the map. The horizontal lines are called “latitude lines,” and the vertical lines are called “longitude lines.”
  • Grid Squares:Grid lines intersect to form grid squares. Each grid square is identified by a unique combination of letters and numbers.
  • Coordinate Location:The coordinates of a point are determined by finding the intersection of the grid lines that surround the point. For example, a point located at the intersection of the grid lines “A” and “1” would have the coordinates “A1.”

Using a Compass for Navigation

A compass is a device that uses the Earth’s magnetic field to determine direction. It is an essential tool for land navigation, as it allows you to maintain a consistent course and avoid getting lost.

  1. Identify North:The first step in using a compass is to identify north. This is done by holding the compass level and allowing the needle to settle. The needle will point towards magnetic north.
  2. Set Bearing:Once you have identified north, you can set a bearing. A bearing is the angle between north and your desired direction of travel.
  3. Follow Bearing:To follow a bearing, hold the compass level and align the needle with the desired bearing. Walk in the direction indicated by the compass needle.
  4. Check Bearing:It is important to check your bearing regularly, as you may drift off course due to wind or other factors.
