Instructions #2

After the students have completed the note taking portion of the assignment they should proceed on to the following instuctions on topographic map making.

  1. To make the map (from the data included here) students should obtain a sheet of graph paper.
  2. Then take the sheet of graph paper and label the x and y axis as longitude and latitude.
  3. The student will then need to determine the scale. Determine the maximum values and minimum values of longitude and latitude, these values should be approximated from the data. For example:
  4. A student has latitude readings which range from 10.00 degrees to 12.00 degrees. The graph paper has 20 squares. This means that each square on the graph paper will represent .05 degrees of latitude.

    Follow the same procedures for the longitudes.

  5. Next begin graphing the elevation data. To do this find the point where the longitude and latitude points cross. Mark that point with an x or dot. Also record the elevation of that point on the graph. Continue this procedure until all of the data is plotted on your graph paper. It is suggested that the student use different colors of x's or dots to indicate the different elevations.
  6. Next connect the dots of similar elevation to one another. Typically elevations within 1 or 2 meters of each other are considered the same elevation for mapping purposes. Again it is suggested students use different colors for different elevations.
  7. You final product should look like the example map included here.
  8. Data is included on the next page.
