Incorrect Stats Perform coordinate system #299

Closed probberechts closed 1 month ago

probberechts commented 4 months ago

Kloppy defines the following coordinate system for Stats Perform tracking data:

origin = BOTTOM_LEFT
vertical_orientation = BOTTOM_TO_TOP
x_dim = [0,100]
y_dim = [0,100]

However, this does not seem to correspond with any of the 4 coordinate systems used by Stats Perform.

Also, it is currently not possible to implement any of these coordinate systems in the data model of kloppy, because the true length and width of the pitch are not defined in the source data.
