Learning Objectives:
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
