OBJECTIVES:

• To gain an understanding of map projections by researching and comparing projections; and

• To create a set of output maps that visually support the comparison of the various map projections and highlights the advantages and disadvantages of the projections.

PROCESS

Using the knowledge you have gained from your previous ArcView exercises, choose a theme of interest to you, and create a thematic map of the world.  Once you have created your map, choose at least one partner who has a different projection (i. e., a different "projection surface" - plane, cylinder, cone, compromise). Make comparisons between and among your projections based on visual assessment and measurements. For example, view your various output overlaid on each other on the light table; compare country boundary differences; compare the size and shape of parallels and meridians; or measure angles and lengths of objects on the map. Be creative!

Experiment with the projections options to create a series of "maps" and "layouts" in your ArcView project that are examples of your projection and the others that you choose to compare it to. Create layouts of the entire map area but also create layouts that are "zoomed in" on various areas for comparison.

Each person is to submit a 4-5 page (double spaced with one inch margins on all sides) paper on your projection, its characteristic, uses, and history, along with a detailed description of the advantages and disadvantages of the projection. (The 4-5 pages does not include the required title page, bibliography and diagrams.) In addition, include a comparison section that compares your map projection to your partner's projection. Finally, interpret your map data and describe the spatial patterns that you see. Your grade is based on the depth and extent of your research as well as the presentation of the projection through output. Your paper should include various maps that describe and support your research. These maps should be referenced and arranged in your paper as figures. All maps will be judged on the correct use and placement of the necessary map elements; selection of appropriate colors, text font and sizes, line size, etc.; the quality of the map layout; and proper database management.
