  • I’ve personally never heard of companies who can produce a paper for you until word got around among my college groupmates. My professor asked me to write a research paper based on a field I have no idea about. My research skills are also very poor. So, I thought I’d give it a try. I chose a writer who matched my writing style and fulfilled every requirement I proposed. I turned my paper in and I actually got a good grade. I highly recommend ⇒ www.HelpWriting.net ⇐

Lesson 9 How Do I Measure Height On A Map

  1. 1. Lesson 9: How do I measure height on a map? Aim: An ability to use contour lines and spot heights to interpret altitude on maps.
  2. 2. Starter <ul><li>Do the odd one out activity with your partner (see worksheets). </li></ul>
  3. 3. Main Activity 1 <ul><li>Q1 Describe the relief shown in this picture. </li></ul><ul><li>Q2 How could you show it on a map? </li></ul><ul><li>Q3 Why would you want to show it on a map? </li></ul><ul><li>Create a short acted sequence to show what it would be like to walk over this terrain. </li></ul>
  4. 4. So how is height shown on maps? <ul><li>SPOT HEIGHTS </li></ul><ul><li>Spot heights are those points that the OS has measured to be exactly that height (in metres) above sea level. They are marked on the map thus: </li></ul><ul><li>.123 </li></ul><ul><li>Always with a small dot marking the exact point. </li></ul>
  5. 5. This is what they look like on Ordnance Survey maps:
  6. 6. Now find an actual spot height on the OS map on your table. <ul><li>Q4 What is its six figure grid reference? </li></ul>
  7. 9. Steep Slope <ul><li>Close together contour lines show a steep slope or gradient. </li></ul><ul><li>Q5 Find a slope on the map. What is its four figure grid reference? </li></ul>
  8. 10. Gentle Slope <ul><li>Contour lines widely spaced show a gentle slope or gradient. </li></ul><ul><li>Q6 Find a gentle slope on the map. What is its 4 figure grid reference? </li></ul>
  9. 11. Hill <ul><li>This set of contour lines represents a hill. The peak of the hill actually has a spot height of 386 marked upon it You can see that the contour lines form concentric 'circles' (complete loops of contour lines within another loop and so on). This is what defines the structure as a 'complete hill' rather than a slope or part of another feature. </li></ul>
  10. 12. Look at the information page then take the test <ul><li>Information1: </li></ul><ul><li>http://www.mapzone.co.uk/pageshomeworkhelp/mapability/reliefandcontourlines/ </li></ul><ul><li>Information 2: </li></ul><ul><li>http://academic.brooklyn.cuny.edu/geology/leveson/core/linksa/contourlabel.html </li></ul><ul><li>Test: </li></ul><ul><li>http://academic.brooklyn.cuny.edu/geology/leveson/core/linksa/ctrprob1x.html </li></ul>
  11. 13. Plenary: <ul><li>Q7 What is the most accurate way to measure altitude on a map? </li></ul><ul><li>Q8 What is the best way to use altitude marks on a map to plan a walk? </li></ul><ul><li>Homework- Find out the altitude of your home. </li></ul>
