Land Navigation

Fundamentals of Land Navigation

Land navigation is a crucial skill for outdoor enthusiasts, military personnel, and adventurers. This section will provide an introduction to the basic fundamentals of land navigation, discussing maps and their types and the basic functions of a compass.

Maps and Their Types

A map is a graphical representation of a geographic area, displaying various features and landmarks to help users navigate their surroundings. There are several types of maps that serve different purposes in land navigation:

  • Topographic Maps: These maps provide detailed information about elevation and terrain features. They depict contour lines that represent constant elevations, enabling users to understand the shape of the land. Topographic maps are essential for cross-country navigation, as they assist in planning routes and identifying natural landmarks.
  • Road Maps: Road maps primarily focus on transportation routes, such as highways, streets, and railways. They are useful for navigating within urban areas and planning long-distance road trips. However, they may not provide sufficient detail for off-road navigation.
  • Thematic Maps: These maps display specific information about a region or theme, such as geological features, climate, or wildlife distribution. Thematic maps can be used to supplement other types of maps or to provide specialized knowledge about an area.

Compass and Its Basic Functions

A compass is an essential tool for land navigation, as it allows users to determine their direction relative to magnetic north. There are several basic functions of a compass that every user should be familiar with:

  • Magnetic Needle: The red-tipped needle in a compass indicates magnetic north. The user can line up this needle with the compass’s marked north direction to determine their heading.
  • Degree Markings: Around the edge of the compass, there are markings representing 360 degrees. By aligning the magnetic needle with the marked north direction, a user can read their current heading in degrees, which can be helpful for plotting a course on a map.
  • Rotating Bezel: This circular ring around the compass allows users to set a bearing or “heading” by aligning a desired degree with an index marker. This makes it easier to follow a specific direction.
  • Orienting Lines: These parallel lines on a compass’s baseplate enable users to align the compass with map grid lines, ensuring accurate navigation.

By combining the use of a compass with a suitable map, such as a topographic map, individuals can effectively plan and navigate through various landscapes, even in challenging conditions. It’s a vital skill to master for anyone venturing into the great outdoors.

Map Reading Skills

Understanding Scale

In land navigation, understanding the scale of a map is crucial. It indicates the ratio between the distance on the map and the actual distance on the ground. For instance, a 1:50,000 scale means that 1 unit (inch, centimeter, etc.) on the map represents 50,000 units on the ground. This helps users gauge the distance between landmarks, plan routes, and estimate travel times.

  • Common map scales are 1:24,000, 1:50,000, and 1:100,000.

Identifying Landmarks and Terrain

Map reading involves identifying landmarks and terrain features that can aid in navigation. Maps use various symbols, colors, and lines to indicate different types of features, such as:

  • Water: Blue lines and shapes represent rivers, streams, and lakes.
  • Vegetation: Green areas indicate dense vegetation (forests), while lighter or colorless areas suggest open terrain.
  • Elevations and contour lines: Brown contour lines show the elevation and topography of the land, with closely spaced lines indicating steep slopes and widely spaced lines indicating gentle or flat terrain.

Landmarks such as buildings, roads, and man-made structures can help orient the user and provide waypoints during navigation.

Left and Right Edges

It’s essential to pay attention to the left and right edges of a map, as they may provide crucial information about the layout and usability of the area. Map edges may show neighboring areas, indicate the north direction or magnetic declination, and provide a legend or key to understand map symbols and shading.

  • Make note of useful information found on map edges.
  • Check if the map you’re using provides information on magnetic declination, which is the angle between magnetic north and true north.

Mastering these basic map reading skills can significantly improve your land navigation abilities and make it easier to navigate unfamiliar terrain confidently and efficiently.

Using a Compass

Taking Bearings

To determine the direction, or bearing, between two points, follow these steps:

  1. Place your compass on the map, aligning the edge of the baseplate with the starting point and the destination.
  2. Ensure the direction of travel arrow points toward the destination.
  3. Rotate the bezel until the orienting lines on the compass housing align with the map’s vertical grid lines, and N (north) points to the top of the map.
  4. The number at the index line will indicate the bearing, in degrees, between the starting point and the destination.

Remember that bearings are measured in degrees (from 0 to 360) with the four cardinal points (north, east, south, and west) corresponding to 0/360, 90, 180, and 270 degrees, respectively.

Declination Adjustment

Declination is the angle between magnetic north and true north, which varies depending on the location and gradually changes over time due to tectonic plate shifts. It is crucial to account for declination when using a compass for navigation. Here are the steps to adjust for declination:

  1. Determine the declination for your current location. This information can be found on most topographic maps or through online resources.
  2. Some compasses have a declination adjustment feature. If your compass has this, simply follow the manufacturer’s instructions for adjusting the declination.
  3. If your compass does not have a declination adjustment feature, you will need to manually adjust for declination when taking bearings. Add or subtract the declination value from the bearing, depending on the direction of the declination (east or west).

By following these steps, you will successfully use a compass to determine bearings and adjust for declination, ensuring accurate navigation in the great outdoors.

Basic Land Navigation Techniques

Point A to Point B Navigation

Basic land navigation techniques can help people navigate from Point A to Point B more effectively. This skill requires a fundamental understanding of maps, terrain, and orientation. It’s essential to stay on track and make the necessary corrections during travel.

One common approach is dead reckoning. Dead reckoning involves estimating your current position based on your previous location, speed, time, and direction. To effectively utilize this method, you need a strong sense of direction and the ability to gauge distances accurately.

Navigating with a Map and Compass

Using a map and compass is crucial for accurate navigation. A map provides valuable information on terrain and notable landmarks, while a compass allows you to find the right direction.

  • Maps: When reading a map, be familiar with major features, symbols, and other critical information. Pay attention to contour lines, which indicate elevation, as well as rivers, roads, and other geographical features.
  • Compass: A compass helps you determine bearings and maintain your intended direction. A bearing is a navigationally precise way to describe a direction, expressed in degrees. For example, instead of going northwest, you would follow a bearing of 315 degrees.

To navigate with a map and compass, follow these steps:

  1. Fold the map: Fold it so that your starting point (Point A) and your destination (Point B) are visible together.
  2. Orient the map: Align the map’s north-south gridlines with the north-south direction on your compass.
  3. Determine your bearing: Line up the edge of the compass on the map between Point A and Point B. Then, read the bearing from the compass.
  4. Follow the bearing: Hold the compass level and steady in front of you. Turn your body until the compass’s needle lines up with the specified bearing. You are now facing the correct direction.

By mastering these basic land navigation techniques, individuals can confidently navigate various terrains and improve their overall navigation skills.

Advanced Techniques


Resection is a technique used to determine one’s location on a map by using a compass to sight and identify at least two known landmarks. To perform resection:

  1. Identify two or three known landmarks on the map and on the ground.
  2. With the compass, measure the magnetic azimuth of each identified landmark from your position.
  3. Convert the magnetic azimuth to a grid azimuth by subtracting or adding the magnetic declination (depending on the location).
  4. Plot the grid azimuth lines from the landmarks on the map, extending the lines so that they intersect. The point where the lines intersect is your approximate location.

Resection is useful in situations where a GPS receiver or phone is not available, but requires knowledge of using a compass and a good understanding of the local geography.

Using a GPS Receiver

A GPS (Global Positioning System) receiver can significantly improve land navigation by providing accurate latitude and longitude information. To effectively use a GPS receiver in land navigation:

  1. Ensure the GPS receiver has a good satellite signal, preferably with a clear view of the sky.
  2. Configure the GPS receiver to display coordinates in the same format as the map being used (e.g., Universal Transverse Mercator, Military Grid Reference System).
  3. When possible, use the GPS receiver’s built-in waypoints, tracks, and routes features to plan and navigate your journey.
  4. Regularly consult your GPS receiver and map together to keep track of your progress and location. Note that while a GPS receiver can provide instant and accurate location information, it is still essential to have map-reading and compass skills as a backup.

Some smartphones have built-in GPS receivers and can perform many of the same functions as dedicated GPS devices. However, relying solely on a phone for navigation may be risky due to battery life limitations, the need for a data connection, and potential damage to the device from environmental factors. It is always best to have multiple navigation tools and skills available while in the field.
