Lab 7

Data classifications and mapping

• For your lab log, list specific guidelines from Making Maps for each of the map types (see below), list your design choice, and why you made it. Obviously, make the changes in your ArcGIS Pro project.

  • a Choropleth (graduated color) map

    

    • data classification choices: Making Maps, pp. 173-181

      • I have a 6 class are map for my counties, if you were to include the class of no data It would be 7 class. I also changed the colors to be more eye catching. My quantitative scheme was also changed through my dot density map as I changed the point data to represent 1 dot = 1500 from 1 dot = 20,000 making the data more extreme. The equal interval scheme is unchanged.

    • symbolization choices: Making Maps, pp. 220-221)

      • For my Choropleth map I changed the color scheme, with value legend and boundaries.

  • a graduated symbol map

    

    • data classification choices: Making Maps, pp. 173-181

      • For this I changed the symbols and their color based on population monochromatic through their value

    • symbolization choices: Making Maps, pp. 220-223

      • I used a classified legend with shapes.

  • a dot density map

    

    • don’t have to classify data

    • symbolization choices: Making Maps, pp. 226-227

      • I lowered the population per dot from 1 = 20,000 to 1 = 1500. The size was changed as well so that this change wouldn’t be overwhelming and become a big blur.
