Projections

Projections used in State Plane Coordinate Systems

Types of Projections

  • State Plane Coordinates Presentation by Dr. Ghilani
  • National Geospatial-Intelligence Agency Geodesy and Geophysics
  • Fundamentals of the State Plane Coordinate Systems by Joseph F. Dracup, Sept 1974. National Geodetic Survey
  • Map Projections: A Working Manual by John P. Snyder. USGS Professional Paper 1395. Washington, D.C.: USGS, 1993.
  • UTM
