Definitions¶

• W24BaseFeatureCoordinate (object): Coordinate point
  Attributes: x: x position normalized by the thumbnail's width
  y: y position normalized by the thumbnail's height.

• W24BaseFeaturePosition (object): Position of the Feature on the individual thumbnails normalized by the width and height of each thumbnail.
  Each features position is indicated as a list of coordinates. If the list only has two elements, you are dealing with a line. If it has four or more, you are looking at a polygon
