By using the request parameter showMapReferences
, developers can enhance specific response items with map references, to enable connection with other services or data applications.
The following table lists currently supported values for showMapReferences
:
Example of a /revgeocode
response with showMapReferences=segments,links,pointAddress,adminIds,cmVersion
:
Note
linkId
is deprecated and removed, it's replaced bycmId
.sideOfLink
is deprecated and removed, it's replaced byside
.link.side
andsegment.side
for the same entity are the same if the link direction aligns with the segment direction. However, they can differ if the link direction does not match the segment direction.
- Forward link direction is defined as the direction from the reference node to the non-reference node. If latitude of reference node is smaller than non-reference node, the direction is from southernmost to northernmost. If latitude of both end nodes are identical and their longitudes differ, the direction is from westernmost node to easternmost node.
- Forward segment direction is defined as the direction from the segment start node to the segment end node.
- The previous parameter
show=hmcReference
is deprecated and replaced byshowMapReferences=segments
which serves the same purpose.
