How To Use A Map And Compass: The Basics

Understanding Maps

Maps are essential tools for navigation and understanding the world around us. They provide valuable information about the terrain, landmarks, and routes that we can follow to reach our desired destination. There are different types of maps that serve various purposes, depending on the specific needs of the user.

Different types of maps

One of the most common types of maps is the topographic map. This type of map provides detailed information about the elevation, contours, and features of the land. It is especially useful for hikers, backpackers, and outdoor enthusiasts who need to navigate through challenging terrains. Other types of maps include road maps, city maps, and thematic maps that focus on specific themes such as vegetation or population density.

Map symbols and legends

Maps are filled with symbols and legends that represent various features and elements of the landscape. These symbols allow us to quickly and easily identify landmarks, bodies of water, roads, and other important details. The legend or key is usually located on the map and provides a guide to understanding the meaning of each symbol. By familiarizing yourself with these symbols and legends, you can effectively interpret the information presented on the map.

Scale and distance

Understanding the scale of a map is crucial for accurately interpreting distances and planning your journey. The scale is usually represented as a ratio, such as 1:50,000, which means that one unit on the map represents 50,000 units in the real world. By measuring the length of a line on the map and applying the scale, you can determine the actual distance between two points. This is especially important when calculating the time it will take to travel and estimating the effort required for a particular route.

Orientation and direction

Being able to orient yourself on a map is essential for successful navigation. The orientation of a map refers to aligning it with the true north, which allows you to accurately determine your direction of travel. Most maps are oriented with the top of the page facing north, but it is important to confirm this using a compass. Understanding direction is crucial when planning routes, following trails, and avoiding getting lost in unfamiliar places.

Choosing the Right Compass

Compasses are invaluable tools for navigating with a map. They help you determine your direction and align the map accurately. There are different types of compasses available, each with its own advantages and use cases.

Types of compasses

The most common type of compass used for outdoor navigation is the baseplate compass. This compass has a clear baseplate with rulers and scales, allowing you to measure distances and plot routes on the map. Thumb compasses are often used by competitive orienteers since they are smaller and more convenient to use while running. Lensatic compasses are often preferred by military personnel as they are rugged and reliable. Whichever type of compass you choose, make sure it suits your specific needs and preferences.

Features to consider

When choosing a compass, there are several features to consider. Look for a compass with a liquid-filled housing to ensure the needle remains stable even when moving. A declination adjustment feature is vital as it allows you to compensate for the difference between magnetic north and true north. A rotating bezel or dial is also crucial for taking accurate bearings. Consider the size and weight of the compass, as well as any additional features such as a magnifying glass or luminous markings for easy visibility in low-light conditions.

How to handle and care for a compass

Properly handling and caring for your compass is essential to ensure its accuracy and longevity. Avoid dropping the compass or subjecting it to extreme temperatures. Keep it away from magnetic objects such as cell phones or metal objects, as they can interfere with the needle. Store your compass in a protective case to prevent damage and always clean the lens and dial to maintain clear visibility. Regularly check for any signs of wear and tear, and if necessary, replace the compass to ensure reliable navigation.

Orienting the Map

Orienting the map means aligning it with the compass so that the top of the map corresponds to true north. This is a crucial step in accurate navigation, as it allows you to properly interpret the information presented on the map and plan your routes accordingly.

Aligning the map with the compass

To align the map with the compass, lay the compass on the map so that the direction of travel arrow points towards the top of the map. Rotate the map and compass together until the magnetic needle aligns with the orienting arrow on the compass housing. Once the needle aligns with the arrow, the map is now aligned with the true north. Take care to keep the compass and map flat while aligning them to prevent any errors.

Using landmarks or features

In addition to aligning the map with the compass, using prominent landmarks or features in the landscape can help further verify your orientation. Look for landmarks that are clearly identifiable on both the map and the actual terrain. These can include mountain peaks, distinctive buildings, or even road intersections. By referencing these landmarks on the map, you can ensure that your orientation is accurate and that you have a clear starting point for your navigation.

Using magnetic declination

Magnetic declination is the angle between magnetic north and true north and varies depending on your location. It is important to adjust for magnetic declination to ensure accurate navigation. To determine the declination for your area, consult a local map or research online resources. Once you know the declination angle, use the adjustment feature on your compass to correct for it. By accounting for the declination, you can align the map with the compass more precisely, leading to more accurate navigation.

Using Compass Bearings

Compass bearings are an essential tool for navigating with a map. They allow you to accurately determine your direction of travel and stay on course. Understanding the difference between magnetic north and true north is crucial for using compass bearings effectively.

Understanding magnetic north vs. true north

Magnetic north refers to the direction indicated by the compass needle, which is influenced by the Earth’s magnetic field. True north, on the other hand, is the direction towards the North Pole. The difference between the two is known as magnetic declination, which we discussed earlier. When using compass bearings, it is important to account for this difference to ensure accurate navigation.

Taking a bearing

To take a bearing, hold the compass flat in your hand and align the direction of travel arrow with a specific landmark or target point. Rotate the bezel or dial until the orienting arrow aligns with the magnetic needle. The number or degree indicated by the index line on the bezel or dial is your compass bearing. This bearing can then be used to navigate towards your desired destination.

Following a bearing

Once you have determined your bearing, it is important to keep track of it while navigating. Hold the compass in front of you and make sure the direction of travel arrow points straight ahead. Take note of any landmarks or terrain features that align with your bearing and use them as guide points to stay on track. Periodically check your compass to ensure you are maintaining the correct bearing and make adjustments as necessary.

Contour lines are evenly spaced lines that connect points of equal elevation on a map. The vertical distance between each contour line is known as the contour interval. By understanding the contour interval, you can determine the steepness of slopes and identify key elevation changes on the map. A closely spaced contour interval indicates a steep slope, while widely spaced contours indicate a relatively flat area.

Identifying terrain features

Contour lines can also help you identify and visualize various terrain features. For example, closely spaced contour lines represent steep slopes, while wide-spaced lines indicate flat or gently sloping areas. If contour lines form concentric circles, it suggests a hill or peak. Conversely, contour lines that form a “V” shape represent a valley or depression in the landscape. By interpreting the contour lines, you can gain a better understanding of the terrain and plan your navigation accordingly.

Navigating through elevation changes

Elevation changes can significantly impact your navigation, especially when encountering steep slopes or cliffs. Contour lines provide valuable information about the elevation changes along your route. If you need to ascend or descend a slope, look for contour lines that are closely spaced together, indicating a steep incline. By following contour lines around the slope, you can find a more gradual path to navigate. Taking into account elevation changes can help you avoid difficult or dangerous terrain and choose the path that best suits your abilities and preferences.
