  • Compose data integrity statements for a geostatistical or spatial analysis to be included in graphic output
  • Identify software tools available to support metadata creation
  • Interpret the elements of an existing metadata document
  • Explain why metadata production should be integrated into the data production and database development workflows, rather than treated as an ancillary activity
  • Outline the elements of the U.S. geospatial metadata standard

DM-14 - Classic vector data models
  • Illustrate the GBF/DIME data model
  • Describe a Freeman-Huffman chain code
  • Describe the relationship of Freeman-Huffman chain codes to the raster model
  • Discuss the impact of early prototype data models (e.g., POLYVRT and GBF/DIME) on contemporary vector formats
  • Describe the relationship between the GBF/DIME and TIGER structures, the rationale for their design, and their intended primary uses, paying particular attention to the role of graph theory in establishing the difference between GBF/DIME and TIGER files
  • Discuss the advantages and disadvantages of POLYVRT
  • Explain what makes POLYVRT a hierarchical vector data model
KE-01 - The process of GIS&T design
  • Describe the major approaches to the design of geospatial systems
  • Analyze past cases to identify best practices of design and implementation
  • Compare and contrast the relative merits of the use-case driven and architecture-centric design processes
DM-58 - Content standards
  • Differentiate between a controlled vocabulary and an ontology
  • Describe a domain ontology or vocabulary (i.e., land use classification systems, surveyor codes, data dictionaries, place names, or benthic habitat classification system)
  • Describe how a domain ontology or vocabulary facilitates data sharing
  • Define “thesaurus” as it pertains to geospatial metadata
  • Describe the primary focus of the following content standards: FGDC, Dublin Core Metadata Initiative, and ISO 19115
  • Differentiate between a content standard and a profile
  • Describe some of the profiles created for the Content Standard for Digital Geospatial Metadata (CSDGM)
FC-36 - Events and Processes
  • Compare and contrast the concepts of continuants (entities) and occurrents (events)
  • Describe the “actor” role that entities and fields play in events and processes
  • Discuss the difficulty of integrating process models into GIS software based on the entity and field views, and methods used to do so
  • Apply or develop formal systems for describing continuous spatio-temporal processes
  • Evaluate the assertion that “events and processes are the same thing, but viewed at different temporal scales”
  • Describe particular events or processes in terms of identity, categories, attributes, and locations
  • Compare and contrast the concepts of event and process
AM-64 - Calculating surface derivatives
  • List the likely sources of error in slope and aspect maps derived from digital elevation models (DEMs) and state the circumstances under which these can be very severe
  • Outline how higher order derivatives of height can be interpreted
  • Explain how slope and aspect can be represented as the vector field given by the first derivative of height
  • Explain why the properties of spatial continuity are characteristic of spatial surfaces
  • Explain why zero slopes are indicative of surface specific points such as peaks, pits, and passes, and list the conditions necessary for each
  • Design an algorithm that calculates slope and aspect from a triangulated irregular network (TIN) model
  • Outline a number of different methods for calculating slope from a DEM
DM-88 - Coordinate transformations
