What is the geospatial coordinate system used for postion_x and postion_y?

[cocoaaa]

Hi, I'm playing with the trajectory dataset, and would like to ask what is the CRS used to encode the position x and y. I thought it may be EPSG:4326 (aka. Lon-Lat) but many of the values for "position_y" column is beyond the range of (-90, 90). For example, in file prediction_train/result_9048_1_frame.txt,

Can you clarify what is the exact CRS the dataset is using? Thanks!

Hi @cocoaaa : did you get any answer towards the CRS used by the dataset? If so, can you help me too by sharing the answer please? By the way are you also playing with Apolloscape trajectory datasets http://apolloscape.auto/trajectory.html ?

Hello @cocoaaa, @VishalSowrirajan, did you find any solution to this. I am also playing with trajectory prediction data set but the (x,y) seems more to be in image coordinates than world coordinates. If you have any clue, could you please share with me?

Thanks very much.

@JaimeFernandez , Unfortunately, no. In the dataset description, it is mentioned that "Position is given in the world coordinate system. The unit for the position and bounding box is meter". But I am unsure too. Additionally, can you let me know how to calculate the distance between 2 coordinate points in this dataset? I tried using euclidean distance but I don't think it is correct. Please share if you know anything about it.
