7. From the topographic map extract of Mount Gambier, give six-ýgure grid references for features that show the following.
a. Mount Gambier has a large timber industry. b. Mount Gambier is a popular tourist resort. c. Mount Gambier has many sporting facilities. d. Mount Gambier is the centre of a farming region. 8. Approximately how wide is Blue Lake at its widest point? Checklist I have: • identiýed north, south, east and west using the north point • used the key to identify features • used grid references to describe the location of a speciýc feature • used the scale to calculate distances • interpreted topography by considering how close together the contour lines are.
LESSON 8.7 SkillBuilder: Interpreting topological maps
LEARNING INTENTION By the end of this SkillBuilder you should be able to interpret a topological map.
8.7.1 Tell me What is a topological map? Topological maps are very simple maps, with only the most vital information included. These maps generally: • use pictures to identify places • are not drawn to scale • provide no sense of distance • provide general directions • exaggerate the size of certain places • do not show exact routes. However, everything is correct in its interconnection to other points. How is a topological map useful? A topological map is useful as a mental map to help you locate important features. Large areas can be drawn to show the viewer the important points. You could use these in class as summary maps of a topic or as quick sketch maps to illustrate a point or to clarify something for another student. They are also useful for: • giving tourists a snapshot of where features are located • quickly showing how to get to a place • showing very large transport routes such as bus and train routes across a city • planning international þights.
A good interpretation of a topological map: • identiýes and communicates key features • clearly represents and communicates the data.
