Geog 390 Geovisualization: Lab. 4: Review of Lab. 1 – 3 maps.

The “Geog 390 Geovisualization” blog was created for publishing maps generated by Eugeniu Ciolacu, first year MS student at Environmental Sciences, during the Geovisualisation class taking place at University of Idaho, professor Dr. Hejun Kang. Also I will post some of maps made by me or maps that I found interesting. In this lab I have to redesign all maps I made previously during the course in a proper way. The original maps are published in below posts. Please fill free to comment. The qualitative map 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. I made the layout smaller in order to have less empty areas (did not change the scale). Change the legend (less words and remove “Legend”). I changed all texts font to Calibri and the position of title to neat line. Then I played with colors till found a better lucking variant and exported it. The last one was open in GIMP, a free graphical software, where played again with colors and also converted as grayscale. Graphical software have some priority in handling colors in comparison with ArcMap, it allow changing hue, saturation, contrast easily at all image which help a lot to find out good-looking color schemes. Also it support vector data as eps files so there is no lose in details. The qualitative map 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. I changed layout using one of the ArcMap modified template. All texts were changed to Calibri. I completely changed the legend and move the title to the bottom of the page. I used one of sequential color scheme suggested by scheme ColorBrewer website with some changes. The map was exported as picture and open in GIMP where play with color in order to obtain a better color scheme. Also I made a map with one of the ArcMap divergent color scheme option. Also remade in GIMP. 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. I made just some minor changes: remove “Legend”, add scale to inset map, changed a little background color, and made less red on map. The map above presents differences between two methods of simplification in comparison to original not simplified data: Special Visvalingam method (Mapshaper website The map was created with Macromedia Freehand, a vector graphical software, and represents Boulder, Colorado area. The map show Rocky Mountain National Park, Indian Peaks Wilderness, roads, rivers and localities. The map was generated based on Geog 390 course materials. I changed the text to Calibri, made smaller size. Changed colors for localities and rivers. Play with hue and lightness in GIP. The map shows differences between different methods of classification based on percentage of white population in Idaho for 2000. The maps were generated based on U.S. Census data. To construct maps was used next types of classifications: Natural Breaks, Equal Interval, Quantiles and Optimal. Source.
