Requirements

  • Shape file data needs to be submitted as NAD83 Datum or WGS84 Datum with a Coordinate Reference System of Latitude/Longitude
  • Shape files must contain valid data and have correct data for their shape type (i.e. lines must contain at least two points; polygon must have at least three points, etc.)
  • Shape files are of the actual underground facilities NOT grids
  • Name the shape file with your member code


Files To Include
  • .DBF (database file)
