What a conversion to GeoJSON changed in a shape, for a change of an Original.

Used by Original.

  • curves_linearized

    Curves linearized

    Curves, such as arcs and splines, became straight segments. The tolerance is the largest distance between a curve and its segments.

  • reprojected

    Reprojected

    The coordinates moved to another coordinate reference system. The Original's crs is the system of the original.

  • simplified

    Simplified

    Positions were removed. The tolerance is the largest distance that the shape moved.

  • coordinates_rounded

    Coordinates rounded

    The coordinates were rounded. The tolerance is the largest distance that a position moved.

  • heights_dropped

    Heights dropped

    The heights (z) of the positions were removed.

  • measures_dropped

    Measures dropped

    The measures (m) of the positions were removed. GeoJSON has none.

  • solid_to_footprint

    Solid to footprint

    A solid became the area that it covers on the ground.

  • surface_to_polygons

    Surface to polygons

    A surface, such as a triangulated surface, became polygons.

  • repaired

    Repaired

    A shape that was not valid was made valid, such as a ring that was closed.

  • clipped

    Clipped

    The shape was cut to an area.

  • parts_merged

    Parts merged

    Several shapes became one.

  • other

    Other

    Any other change. The change's description says what.
