LINK_ID | Permanent link ID. Positive 64 bit Integer that globally identifies the road, carto or building footprint link, also across map releases. Link IDs are never reused. |
DTM_MIN_HEIGHT | The minimum height [cm above WGS84 ellipsoid] encountered along the link. |
DTM_MAX_HEIGHT | The maximum height [cm above WGS84 ellipsoid] encountered along the link. |
DTM_AVG_HEIGHT | The average height [cm above WGS84 ellipsoid] along the link. |
DTM_REF_ZCOORD | Height [cm above WGS84 ellipsoid] at the reference node of the link. |
DTM_NONREF_ZCOORD | Height [cm above WGS84 ellipsoid] at the non-reference node of the link. |
