READING A TOPOGRAPHIC MAP – A* The most obvious way in which topographic maps differ from other maps is that they contain many thin, curved lines that appear to wrap around certain areas. These lines are called contour lines. They connect points of equal elevation.

To make topographic maps easier to read, every fifth contour line is an index contour. Because it's impractical to mark the elevation of every contour line on the map, the index contour lines are the only ones labeled. The index contours are a darker or wider brown line in comparison to the regular contour .

Index contour lines: Every fifth contour line is a thicker, “index” some point along that line, its exact elevation is listed. Contour interval: The change in elevation from one contour line to the next is always the same within the same maps have either a or foot contour interval: An foot interval simply means that each contour line is 80 vertical feet away from Author: REI Staff.

Contour Map Generation •Example: •Contours are to be placed every ten feet. d = feet • There are to be three contour lines on this interval. • Divide feet by 3 to get one contour every feet.

• Mark four points (two on the endpoints, and two between) and draw the Size: 2MB. The better you understand the fish you’re targeting, the more you’ll know what to look for on a fishing map with contour lines.

Focusing on Fishing Hot Spots The last step in this process is wrapping together what you know from both of the previous steps, and keying in on the specific areas on your waterway where depth, structure, and fish. After reading contour lines on a map for a while, you’ll notice that a few distinct shapes pop again and again.

Learning to identify common contour line formations will help you read topo maps quickly, and recognize the various terrain features they represent on a map.

Let's dig into 'em. Peak Ring. To be able to use these types of maps out in the wilderness, you need to learn how to read a topographic map.

When reading a topographic map, you need to visualize a 3-dimensional view of what the symbols and contour lines on the map are showing. The following image below illustrates how a topographic map conveys three-dimensional information. Hills, slopes and mountains are represented on a map using contour lines.

By studying the contour lines you can work out lots about the surrounding terrain including gradients of hills, valleys and steepness of climbs.

Check out our Pathfinder guide titled Navigation Skills for Walkers including map reading, compass and GPS. Black - Indicates cultural (man-made) features such as buildings and roads, surveyed spot elevations, and all labels.

Red-Brown - The colors red and brown are combined to identify cultural features, all relief features, non-surveyed spot elevations, and elevation, such as contour lines on red-light readable maps. Contour Lines vs. The Real World As reliable as a topographic map may be, it can't tell reveal every detail of the terrain.

A foot-high cliff or a foot deep ditch could lie between two foot contour lines ~ and you wouldn't know it because it won't be indicated on the map in any way. Introduction to Map Reading legend the section on a map that contains the symbols you need to read the map Figure The Bottom of a Map Figure Map Legend The map legend identifies the symbols used to depict the prominent natural and man-made objects that exist on the ground.

These symbols are not the same on every map, especially. On the map, if contour lines are close together, it represents a steep incline, like a mountain. If the lines are farther apart, then the terrain is more : Geoff Nudelman. The Lines-Contour Interval: Every contour map will contain what is known as a contour number tells you (the map reader) how many feet (or meters, or kilometers) is gained or lost between the lines on the map.

To save confusion and clutter on a contour map it is typical to only label some of the contour lines (like every 5th one). To read the contour lines on a map, first note the direction your map faces.

Most maps are oriented with north at the top of the map. The first step in understanding contour lines is to check out your map’s legend to see what your contour interval is. The primary feature of a topographic map are the contour lines.

These lines show changes in elevation and are layered with a variety of information describing the terrain—such as rivers, creeks, tree coverage, power lines, streets, trails, and more.

How to Read One. Topo maps provide a lot of information in a small amount of space. Now it is time to practice and apply your recently gained skills in "Reading a Contour Line". This "Practical Quiz" offers various examples of topographic maps and asks you to answer the questions associated with each map.

The questions are similar to the map questions you have dealt with throughout this webpage and will cover determining.

Tan YS 4 Map reading notes Introduction In the course of 2 or 3 years course, Candidates will be exposed to topographical maps from tropical countries such as Mauritius, Tanzania, Zimbabwe and Jamaica. Many of the topographical maps of these developing countries show landscapes which are basically rural with some urban settlements in the making.

Reading Elevation From Contour Lines: The numbers written on contour lines indicate the elevation of the lines. Topographic maps would be very cluttered if all contour lines were labeled, so only the heavier lines show labels.

lines can be determined using the contour interval at the bottom of the map. The contour interval tells the. It goes over how to read the basic terrain features shown on contour lines on a typical topographical map. It shows ridges and valleys as well as peaks and depressions, and cliffs.

I am taking machine learning, and I have seen a few contour plots in the course. It seems that I can't understand how to read this plot, I have tried looking it up in Wikipedia, but I don't even understand the first example (the figure on the right).

Another example is from the course. Geographers measure the height, or elevation, of land from sea level.

In this lesson, students learn about sea level and elevation, then answer questions based on a profile map, a contour map, and an elevation map. The purpose of this Manual is to enable Emergency Personnel to use maps efficiently, and to provide Map Reading instructors with a National It must be emphasised that Map Reading and Navigation, like Contour Interval CONVENTIONAL MAP SYMBOLS Symbols Explanations.

A path running parallel to contour lines is relatively flat. When reading a topographic map, you need to visualize in your mind's eye a 3-dimensional view of what the symbols and contour lines are representing.

The most important thing to remember is that CLOSE contour lines mean STEEP terrain and OPEN contour lines mean FLAT terrain.They are easier to read than small-scale maps, but they cover less area.

It takes fourmaps (where one inch equals about one mile) to cover the same ground as amap (one inch equals about four miles). HOW TO READ CONTOUR LINES. Look at the map of Baldy Mountain at Philmont Scout Ranch. The brown lines are contour lines.Contour maps have also been referred to as isometric maps or isopleth maps.

Contour maps are used to display data related to temperature or topographic information. Most of the time, contour maps are used to display maps related to geology or mountains. The contour lines represent which sections of the mountains are steeper based on how close.
