map design techniques | GIS&T Body of Knowledge

Describe how the adding time-series data reveals or does not reveal patterns not evident in a cross-sectional data
Describe how an animated map reveals patterns not evident without animation
Demonstrate how Bertin’s “graphic variables” can be extended to include animation effects
Create a temporal sequence representing a dynamic geospatial process

Describe situations in which methods of terrain representation (e.g., shaded relief, contours, hypsometric tints, block diagrams, profiles) are well suited
Create a map that represents both slope and aspect on the same map using the Moellering-Kimerling coloring method
Explain how maps that show the landscape in profile can be used to represent terrain
Differentiate 3-D representations from 21/2-D representations
Describe situations in which methods of terrain representation are poorly suited

Differentiate the interpretation of a series of three maps and a single multivariate map, each representing the same three related variables
Design a single map symbol that can be used to symbolize a set of related variables
Create a map that displays related variables using different mapping methods (e.g., choropleth
and proportional symbol, choropleth and cartogram) Create a map that displays related variables using the same mapping method (e.g., bivariate choropleth map, bivariate dot map)
Design a map series to show the change in a geographic pattern over time
Detect a multivariate outlier using a combination of maps and graphs
Explain the relationship among several variables in a parallel coordinate plot

Describe the design considerations for each of the following methods: choropleth, dasymetric, proportioned symbol, graduated symbol, isoline, dot, cartogram, and flow map
Evaluate the strengths and limitations of each of the following methods: choropleth, dasymetric, proportioned symbol, graduated symbol, isoline, dot, cartogram, and flow map
Explain why choropleth maps should (almost) never be used for mapping count data and suggest alternative methods for mapping count data
Choose suitable mapping methods for each attribute of a given type of feature in a GIS (e.g., roads with various attributes such as surface type, traffic flow, number of lanes, direction such as one-way)
Select base information suited to providing a frame of reference for thematic map symbols (e.g., network of major roads and state boundaries underlying national population map)
Create maps using each of the following methods: choropleth, dasymetric, proportioned symbol, graduated symbol, isoline, dot, cartogram, and flow
Create well-designed legends using the appropriate conventions for the following methods: choropleth, dasymetric, proportioned symbol, graduated symbol, isoline, dot, cartogram, and flow
