Lab 6 Topographic Maps Objective: To become familiar with the information displayed on topographic map sheets. While GPS have become ubiquitous and we are becoming more and more a digital society, knowing how to read and use a topographic map is a valuable skill. For this exercise, you will use the topographic map sheet, 092G14, Cheakamus River, which is the area just north of Squamish. You will use the same map again in the last lab of the semester. Each topographic map has features that we will discuss in the lab. 1. What does the scale of a map represent? Give an example and explain. (2) 2. What do contour lines represent? (1) 3. What are the highest and lowest points on the map? What is the total relief? Show your calculations. (3) 4. Draw a topographic profile from Cloudburst Mountain to Sigurd Lake. (10
Explanation / Answer
1. The scale of a map represents the relationship between the distance on the map and the corresponding distance on the actual ground surface. It is usually given as a fraction or a ratio. For example, a map scale of 1:50,000 means 1cm on the given map is equal to 50,000 cm(500 m) on the actual ground surface.
2. On a topographic map, comtour lines are used to represent elevations and these lines are produced by connecting points of equal elevation above mean sea level. Thus, contour lines can represent hills and valleys as well as determine the gentleness or steepness of slopes.
3. Please provide the topographic map sheet numbered 092G14 required to answer question 3 & 4.
