PART III:

PHOTO: Select one of the CIR photos on file for this lab and identify which one you selected.

The following image is a color infrared aerial photo of a suburban area on Long Island. The distinct characteristics of CIR are clearly obvious on the image. After studying the image, perform an analysis and mapping of one or more of the following:

Use a transparent overlay to locate and show areas of:

A. VEGETATION; You might for example include one or more of the following characteristics:

1. health (vigor and/or density)

2. stage of growth (new or mature)

3. type (coniferous vs. deciduous)

B. TRANSPORATION:

1. form or type(rail vs. highway or types of roads by class)

2. material (asphalt, concrete, etc.)

3. age (newly paved will usually have darker tones if made

of asphalt, or very bright white if concrete)

C. WATER:

1. level of turbidity

2. depth

3. presence of vegetation (algae, pollution)

D. LAND COVER

You may use any land cover scheme but you might start with the USGS classification found in your text.

FINAL PRODUCT MUST: Use all cartographic conventions. Indicate scale of image, north arrow, title of your map, legend, and approximate geographic coordinate locations.

For geographic coordinates you may have to consult various topographic or other maps found in the library or other locations.

The legend must list your map categories. In addition, a definition of your categories must be provided—if not in the legend then on a separate sheet of paper attached to the map.
