How to define rrMap in rodrunnerHDMap as multiple rather than just one

I define and use roadrunnerHDMap as rrMap in a single MATLAB script. I want to divide the function called roadrunnerHDMap into several and set up a lane and a lane boundary in each map. Is it possible?

If possible, what are the options?

- example code -

rrMap_1 = roadrunnerHDMap;

rrMap_2 = roadrunnerHDMap;

I defined it as a variable with a different name like the code above, but the results show that both geometry and lane settings are applied the same

Hi JK,

I understand you want to create unique road runner maps with different geometry settings.

The 'roadrunnerHDMap' function creates an empty RoadRunner HD Map, hence the multiple maps created contain the same properties initially.

You can populate the map with lanes, lane boundaries, lane markings, and junctions using 'roadrunnerHDMap' object properties.

Please refer to the following demo example:

rrMap_1 = roadrunnerHDMap;
rrMap_2 = roadrunnerHDMap;

% Add different geometric boundaries to maps %
rrMap_1.GeographicBoundary=[-0.782 -3.13 0;101.565 50 0];
rrMap_2.GeographicBoundary=[-0.287 -1.31 0;565.101 50 0];

% Add different lanes to maps %
rrMap_1.Lanes(1) = roadrunner.hdmap.Lane(ID="Lane1Map1",Geometry=[0.782 -1.56;50.78 23.43],LaneType="Driving", TravelDirection="Forward");
rrMap_2.Lanes(1) = roadrunner.hdmap.Lane(ID="Lane1Map2",Geometry=[0.287 -1.65;50.87 23.34],LaneType="Driving", TravelDirection="Backward");

The above example shows how to apply different settings like Lane and Geographic Boundary to the roadrunner maps.

You can investigate the map objects 'rrMap_1' and 'rrMap_2' in the workspace to observe their properties, which would have now changed.

Hope this helps.
