Lab. 1: Qualitative and quantitative maps, multilayer maps and data simplification.

The qualitative map above presents the dominant racial groups for Buffalo based on three ethnic groups: white, black and hispanic. In order to generate the map was used ethnic data from U.S. Census Survey for 2000 year, data source: University of Buffalo. For representation was used qualitative color scheme (difference in hue or in other words different colors).

The qualitative map above presents the percentage of children from Buffalo of 5-17 year old. In order to generate the map was the same data from U.S. Census Survey for 2000 year, data source: University of Buffalo. For representation was used sequential color scheme (one hue with different lightness).

The map above presents changes of Nez Perce aboriginal homeland reservation from initial homeland to 2006 state. The map was generated based on Geog 390 course materials.

The map above presents differences between two methods of simplification in comparison to original not simplified data: Special Visvalingam method (Mapshaper website http://mapshaper.com/test/demo.html) and Bend Simplify method (ArcToolBox). To generate the map was used Geog 390 course materials.
