Lab 1 Maps

Qualitative Map
Before :

After :

This map shows the 2000 census tracts for the Buffalo area and displays the dominant race for each tract. In the second map, I aligned the north arrow, legend, and scale bar and added the coordinate system information. The legend title was deleted as I didn’t think it was necessary. I also changed the colors in the second to more saturated colors so that the map doesn’t appear dull.


Quantitative Map
Before :

After :

This map shows the 2000 census tracts for the Buffalo area and displays the percent of the population in each tract that is between the ages of 5 and 17, or school age children. In the revised map, I used more saturated colors and darker boundary lines. I lined up the north arrow, legend and scale bar and added the coordinate system information. The legend title was deleted and a legend subtitle, stating the classification method, was added.


Nez Perce Map
Before :

After :

This map shows how the lands of the Nez Perce tribe have shrunk over the years, beginning with their original land, then the land appointed them in 1855 and 1863. It also shows where all lands owned by Nez Perce in 2006 are. I only made a few revisions to this map. First, I deleted the legend title and moved the legend to center it more in the white space. Around all of the major town labels and the reservation line dates, I added a halo to make them more visible. I also moved to labels around to better positions. The north arrow was moved to give the legend more space.


Generalization Map
Before :

After :

The purpose of this map is to show the differences between 2 generalization methods. The first method is ‘Simplify Line’, a tool used in ArcGIS 9.3. The second method is from a website called MapShaper, where I chose the Douglas-Peucker algorithm to generalize the data. Only a small section of the original map was chosen to show how the two differ from the original. In the revised map, I marked out where the example section was in the original data. Scale bars were added for all the views and a north arrow was placed on the map. A legend was added since the river lines in each example were different colors. A subtitle was added to try to make the purpose of the map clearer. Information about the map, such as date of creation and where the data came from, was added.
