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
Identify the hardware and space that will be needed for a GIS implementation
Compare and contrast the relative merits of housing GISs within IT (information technology) and MIS (management information system) facilities versus keeping them separate
Collaborate effectively with various units in an institution to develop efficient hardware and space solutions
Hypothesize the ways in which capital needs for GIS may change in the future
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
Compare and contrast the ethical guidelines promoted by the GIS Certification Institute (GISCI) and the American Society for Photogrammetry and Remote Sensing (ASPRS)
