python3 main.py -m data/borregas_ave.txt
// or

2. Find lane by id

You can use below command to find lane by id, Found lane is shown in Red.

Now you can convert OpenDrive map to Apollo map by following command.

python3 main.py -f -i data/town.xodr -o data/apollo_map.txt

The following is the display of the hd-map in data\borregas_ave.txt.You can click on the lane you want to display more detail info, which will display the current lane's id, as well as the predecessor and successor lane's id in the upper left corner.
