Analysis and Modeling

Knowledge and application of the analytical functions ("exploratory" analyses as well as model-driven analyses) of geospatial software tools.

Critical Work Functions

  • Describe an example of a useful application of a buffer operation in GIS software
    • Perform a site suitability analysis using intersection and overlay functions of GIS software
      • Use GIS software to identify an optimal route that accounts for visibility, slope, and specified land uses
        • Perform dynamic segmentation on transportation network data encoded in a linear reference system
          • Explain how leading online routing systems work, and account for common geocoding errors
            • Use location-allocation software functions to locate service facilities that satisfy given constraints
              • Develop conceptual, logical, and physical models of a geospatial database designed in response to user requirements
                • Explain the Modifiable Areal Unit Problem (e.g. ecological fallacy, choropleth mapping, etc.) with relation to data aggregation
                  • Explain characteristics and appropriate uses of geospatial modeling techniques (e.g. neural networks, cellular automata, heuristics, agent-based models, and simulation models)
                    • Demonstrate familiarity with the existence of predictive models and their applications
                      • Employ cartographic techniques to represent different kinds of uncertainty, including uncertain boundary locations, transitional boundaries, and ambiguity of attributes
                        • Establish, re-establish and/or monument property boundaries; represent such boundaries in plats, records, and descriptions, all under personal and professional liability as stipulated in legal statute and precedent
                          • Determine appropriate image data and image analysis techniques needed to fulfill project requirements
                            • Outline workflows that identify sequence of procedures involved in geometric correction, radiometric correction, and mosaicking of remotely sensed data
                              • Explain how to quantify the thematic accuracy of a land use/land cover map derived from remotely-sensed imagery
                                • Evaluate the thematic accuracy of a data product derived from aerial image interpretation, such as a soils map, using ground verification methods
                                  • Explain the difference between pixel-based and object-based image classification
                                    • Perform object-oriented image classification using specialized software tools
