defeat Poland and the Soviet Union and on
removing or killing the Jews and Slavs.

Symbology Practice
• Problem 1: Please utilize the symbology tool to draw color on your map or file in
order.
• (1) unique: give different color to each county.
• (2) dot density: use president election result from central election commission to
plot different numbers of which candidates have been gained by different color in
dot. (Resolution: county-based)
• (3) graduated color: show the ratio of people who have voted in president
election or not. (Resolution: county-based)
• (4) graduated symbol: show the numbers of people who have voted in president
election. (Resolution: county-based)
• (5) pie and bar: show the ratio and numbers of votes from different candidates.
(Resolution: county-based)
• (6) multiple attributes: show the ratio of Tsai’ vote by multiple attribute.

Symbology Practice
• Problem 2: We have DEM (Digital Elevation Map) of Taiwan, please
use “suitable” colorbar.
• (1) Please load the raster file (img file format) and change its
symbology into a suitable color.
• (2) Please use 500 meters as a division to reclassify(see also Hint for
Week 2 Assignment.pptx) DEM file and change its color.
• (3) Please set 500 meters as a division in symbology tool to redraw
this DEM file.
• (4) What is the difference between the answer of (2) and (3)?
