[autoware] get goal pos from GNSS

edit

I want to global planning only with GNSS(latitude, longitude)

so, i put all my gnss information in point.csv

and using GetDataRowByID function, get GNSS information in the csv, and compare with wanted goal latitude, longitude

but it is very slow, and i can't understand 100% about the vector map format. it's very hard for me,

so is there a way get closest waypoint only from latitude and longitude?

like GetClosestWaypointFromMap function.

thanks
