What's the meaning of property X and Y in the dataset "Argoverse Motion Forecasting v1.1--traing''

[Myfootnotsmelly]

Hi! I'm trying to get the longitude and latitude of every row of dataset but (X,Y) is something like (2661.0156381377,1145.75305191368) which surely does not imply long&lat.
However, i notice there is property "city_name" in the dataset , then what's the base point of the X and Y, and how can i convert it into longtitude and latitude?
Thanks a lot !

Thanks for your interest in our work. (x,y) are measured in meters for the Motion Forecasting Dataset, in the city coordinate system. Our city coordinate system is relative to a point within each city (an origin we define). We discuss this in the Appendix of our paper -- please read me here in this issue: #95

Got it. Thank you for the answer.

Thanks for your answer. I was exploring the new argoverse2 dataset and I noticed you have covered more cities (e.g., Washington DC). Do you also have the origin point and coordinate system for each city in the new dataset?

Thanks
