RoadRunner HD Map create

I finished the example of compiling a protobuf file into c++ to generate a rrhd file.

But here, I tried to build the section I selected, but lane and lane boundary didn't understand how to express the curve, how to specify the coordinates, etc., and I couldn't find it.

Do I have to create a hd map from a compilation of protobuf files into c++??

I tried to create with matlab, but I couldn't find a way to add a lane or express it as a curve.

Is there a document related to the above or a link to refer to it??

Hi,

You can create RoadRunner HD Map (.rrhd) files using either MATLAB or C++. MATLAB provides the roadrunnerHDMap API, which allows you to build lanes, lane boundaries, and other map elements and export them directly to .rrhd format. C++ can generate the same .rrhd files by using the official RoadRunner HD Map protobuf schema files, such as hd_lanes.proto and geometry.proto, which are available within the Scene Builder protocol buffer definitions.

For lane and lane‑boundary curves, RoadRunner HD Map represents geometry as a polyline, meaning you define the curve by supplying multiple (x, y) or (x, y, z) coordinate points in the Geometry fields of the Lane or LaneBoundary objects.
