+Train and Validation split tiles all contain at least 1 pixel in each class. For the Test split, some tiles are entirely the background class. If ignoring the test split tiles which contain only background pixels, the split percentages instead become 70/17/13 for the train/validation/test splits, respectively.
 
 Splits are created such that tiles from the same source orthomosaic image are not divided across different splits. That is, all tiles from the same drone flight are present only in a single split.
