LAB 6 GOG 385: Comparison of Land Use Classification Systems

(revised 06/01)

PURPOSE: To compare the utility of two different land use/land cover classification systems by classifying imagery and constructing maps using both systems.

MATERIALS:

1) LUNR and USGS Classification Manuals

2) Herculine

3) Drafting Pencil and Tape

4) Magnifier

METHOD: Your assignment is to read and understand the LUNR and USGS classification documents provided in the IMC, and perform a level II classification (or its close approximation) on an image with each classification system. The image you will use for this assignment is a high-altitude color infra-red (CIR) transparency which may be selected from the list of available imagery below. SELECT ONE IMAGE to use for both classifications and mapping.

Performing the classification will involve identifying and delineating areal land cover on two separate overlays (1 for USGS system and 1 for the LUNR system), and labeling each polygon or raster element with the correct code. After you are done with the overlays write a 2-page description of the two systems comparing their strengths and weaknesses.

You do not have to do the entire image. You will be given instructions in class regarding which quarter of the image you may select to map.

AVAILABLE IMAGERY

NOTE: Be certain to indicate which image you used to create your maps.

*Only cartographic convention required is photo source and legend indicating the land cover classes you used (with color code) for each map
