For this map analysis assignment, I received a topographic government issue map of Tenino, Washington and its surrounding areas. The history of the map itself and the agency that made it was interesting, yet sparse. There isn’t a lot of information about the map because the Defense Mapping Agency (the creators of this map) was dissolved and restructured in 1996.
I analyzed the contents of the map based on Denis Wood’s 10 Cartographic Codes listed in Rethinking the Power of Maps.
1. iconic [Rivers, lakes, pipelines, railroads, parks, neighborhoods, landmarks, highways, roads, schools, airports, valleys, mountains, elevation changes, regional boundaries, churches, watermill, windmill, wind pump, mines, quarries, control station, woodlands, vineyards, swamps, waterfalls, and rapids.]
2. linguistic [English, Hanaford Creek, Prairie Creek, Monarch Mine, Scott Lake, Deep Lake, Church of God, Olympia Municipal Airport.]
3. tectonic [Scales are detailed and prevalent. The scale is listed at 1:50,000. The elevation is measure in meters from 0 to 5,000; yards from 0 to 5,000; Statute Miles from 0 to 3; and Nautical Miles from 0 to 3. The main contour intervals are every 20 meters with supplementary lines every 10 meters.
4. temporal 
5. presentational [simple, printed, mostly green for forested areas, blue for bodies of water, map at center/ top, keys along the bottom and edges. Nothing on the back, thin off white paper, perhaps a very thin gloss/wax/plastic coating]
6. thematic [scientific, accurate, official
7. topic [Tenino, Washington topographic map]
8. historical [It shows what schools and churches and things have been around since 1975.]
9. rhetorical [Official, accurate, governmental.]
10. utilitarian [road maps, calculating distance, hiking, planning construction, stealthy missions: red-light readable]
C. Side notes:
- The symbols they use are very small which seems to imply that it is not meant as a sightseeing/tourism map.
- There are a lot of scales with instructions to teach people to navigate and calculate magnetic north versus grid north versus true north.
- The map says it is made by the Defense Mapping Agency Topographic Center in Washington D.C.
- You can tell that it is part of a series of interconnecting maps because it is labeled sheet “1477 IV” and there is a subordinate section labeled “adjoining sheets” that shows where is fits in between 1478 III and 1477 III
- Hand written notes on side relate to reading azimuths, calculating angles, and properly record grid coordinates.
- Arrows at the top of the map tell you how far it is to Olympia, Washington (the capitol).
