Thanks
  • Electronic Cultural Atlas Initiative
  • Middle American Research Institute
  • Science Museum of Virginia

Goals
  • Identify systems
  • Social, economic, political ( polities)
  • Use settlement data
  • Use epigraphic data
  • Test theoretical settlement models
  • Predict and identify settlement patterns in
    unsurveyed areas

4
Typical GIS
  • Research OR
  • Modest resources
  • Smaller in scope
  • Geographically limited
  • Data-constrained
  • State/Federal CRM
  • Heavy on resources
  • Public Administration
  • Record-keeping

Scale
  • Area detail
  • Cost
  • Labor
  • Compute power
  • Knowledge
  • required for system use
  • Challenge
  • Enough detail for interesting questions
  • Enough resources for the effort

Digital Chart of the World
  • Developed by United States Department of Defense
    (Defense Mapping Agency)
  • Described in Military Specification Digital
    Chart of the World. MIL-D-89009.
  • Mapped at scale of 11,000,000
  • Horizontal accuracy ? 2000 - 4200 m
