Lab 3: Navigation Maps

Intro: 

The goal of this lab was to create two maps that will be used in a later lab for navigation purposes

Methods:

After given access to a geodatabase filled with data on the specific area of Eau Claire Wisconsin selectivity was used to decide which data was helpful and which was unnecessary to create a map easiest for navigation in the field. Two maps needed to be created, the first with a UTM grid and 50 meter spacing and the other with the area's Geographic Coordinate System Decimals Degrees. A pace count was also recorded for additional assistance in the field, every right step was counted over a 100 meter distance.

Results:

In this first map the main focus is the 2 foot contour lines that show the surface elevation of the area. A aerial photo was placed in the background for visual ground references. This map also includes the UTM grid, pace count and a 50 meter grid.

The second map uses the deep purple to identify the low areas in the terrain and a defined aerial photo for navigational references. This map also includes GCS decimal degrees. Both maps are in the North American  Datum 1983 UTM zone 15 north coordinate system and projected in a Universal Transverse Mercator. The UTM coordinate system that complies 60 6 degree longitudinal zones with little distortion around the earth. Eau Claire Wisconsin happens to be in the 15 north section.
