## map design techniques

##### CV-17 - Mapping Time
• 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
##### CV-14 - Terrain Representation
• 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
##### CV-12 - Bivariate and Multivariate Maps
• 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
##### CV-11 - Common Thematic Map Types
• 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
##### CV-18 - Mapping Uncertainty
• Describe a technique that can be used to represent the value of each of the components of data quality (positional and attribute accuracy, logical consistency, and completeness)
• Apply multivariate and dynamic visualization methods to display uncertainty in data
• Sketch a map with a reliability overlay using symbols suited to reliability representations
• Develop graphic techniques that clearly show different forms of inexactness (e.g., existence uncertainty, boundary location uncertainty, attribute ambiguity, transitional boundary) of a given feature (e.g., a culture region)
