Geo literals with three dimensions

    • Type: Improvement
    • Status: Closed
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: V4.01_CS01
    • Fix Version/s: V4.01_CS02
    • Component/s: ABNF

      GeoJSON only supports Three-Dimension with a third coordinate representing an altitude or elevation.

      GeoJSON notation in principle allows the two "Measured" variants, but RFC7946 strongly discourages its use.

      To not be overly restrictive we should extend the ABNF for Geo types and also allow two optional coordinates:

      positionLiteral = doubleValue SP doubleValue [ SP doubleValue ] [ SP doubleValue ] ; longitude, latitude, altitude/elevation (optional), linear referencing measure (optional)

      Description

      Geo literals in WKT (well-known text) representation as defined by the OpenGIS Simple Feature Access http://www.opengeospatial.org/standards/sfa require two dimensions (longitute, latitude) and allow two optional dimensions

      • Three-Dimension (x,y, z)
      • Two-Dimension Measured (x, y, m) with m being a linear referencing measure
      • Three-Dimension Measured (x, y, z, m)
