Explain the relevance of the concept “parallax” in stereoscopic aerial imagery
Evaluate the advantages and disadvantages of photogrammetric methods and LiDAR for production of terrain elevation data
Specify the technical components of an aerotriangulation system
Outline the sequence of tasks involved in generating an orthoimage from a vertical aerial photograph

Define basic terms of query processing (e.g., SQL, primary and foreign keys, table join)
Create an SQL query to retrieve elements from a GIS
Explain the basic logic of SQL syntax
Demonstrate the basic syntactic structure of SQL

List the variables used in the symbolization of map data for visual, tactile, haptic, auditory, and dynamic displays
Select effective symbols for map features based on the dimensionality and attributes of the geographic phenomena being mapped
Design map symbols with sufficient contrast to be distinguishable by typical users
Illustrate how a single geographic feature can be represented by various graphic primitives (e.g., land surface as a set of elevation points, as contour lines, as hypsometric layers or tints, and as a hillshaded surface)
Identify the visual variables (e.g., size, lightness, shape, hue) and graphic primitives (points, lines, areas) commonly used in maps to represent various geographic features at all attribute measurement levels (nominal, ordinal, interval, ratio)

Demonstrate how the way people do their jobs can affect system management
Describe methods for articulating user needs to internal technical support staff
Describe how system management includes understanding people

Describe the historical context of the USPLS
Discuss the consequences of the USPLS with regard to public administration (i.e., zoning)
Explain how townships, ranges, and their sections are delineated in terms of baselines and principal meridians
Illustrate how to quarter-off portions of a township and range section
Discuss advantages and disadvantages of systematic land partitioning methods in the context of GIS
Differentiate the USPLS from the geographic coordinate system
Describe the New England Town partitioning system
Compare and contrast the United States Public Land Survey System (USPLS) and the Spanish land grant and French long lot systems

Explain how an understanding of use of current and proposed technology in other organizations can aid in implementing a GIS

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
