G2240A Fall2012 Assignment THREE: Terrain Mapping of Area of
DUE : Week of Monday Oct 29th
Brief on this Assignment:
This assignment involves Terrain Mapping, aka Relief Portrayal, of your Research Site. The
terrain mapping must include Relative (qualitatitive, visual), Absolute (quantitative, numerical
elevation values) Relief Mapping Methods and a Combined mapping Product (Absolute on
Relative background). For example, provide a Shaded Relief map (Relative), a Contour map
(Absolute) and a composite that combines the two. Search for data, tools and techniques to
present your three maps.
This is an individual assignment (not done in pairs or groups). Your entire submission should
consist of four (4) pages on regular 8.5x11" sheets of paper. The order should be as follows:
Page 1: Summary (25%) Write a Brief Summary of this Mapping Exercise. Describe
summarily what you set out to do, and what you did in terms of data search, tools used and
methods employed. Add a paragraph or two with your Conclusions, „Lessons Learned‟,
Questions, Suggestions, etc.
Page 2: Relative Relief Portrayal Map (25%) Use a Planimetric (rather than Oblique)
Perspective for this map.
Page 3: Absolute Relief Portrayal Map (25%) Use a Planimetric (rather than Oblique)
Perspective for this map. Get a DEM or Contour data for this map (it is harder to come by
Spot Elevation data). If your site is very small, could you make your own spot elevation map
using Google Earth by moving the cursor and documenting the change in elevation? Present
the map as either a Contour Map or as an Elevation Range Map (with suitable color zones
and Legend). Note that Spot Elevations can be converted to a DEM or to Contours. Also
note that a DEM can be used to derive
