ISO 19115 - GeographyΒΆ

The construction of geographic objects within DDI was done using the US FGDC which is ISO 19115 compliant. The content of the following objects map to these geographic standards:

In SpatialCoverage:

  • Bounding Box

  • Spatial Object (SpatialPrimative)

  • TopLevelReference

  • LowestLevelReference

  • BoundingPolygon

  • Point

In GeographicResponseDomain:

  • Datum

  • CoordianteSystem

  • CoordinateZone

  • ErrorCorrection

  • Offset

  • GeoreferencedObject

  • CoordinatePairs

  • SpatialPrimitive

The use of these fields provides search information for coordinate based search systems and detailed information needed by the geographer to determine the usefulness of a specific data set for geographic analysis.
