semantic-8

semantic-8 is a benchmark for classification with 8 class labels, namely {1: man-made terrain, 2: natural terrain, 3: high vegetation, 4: low vegetation, 5: buildings, 6: hard scape, 7: scanning artefacts, 8: cars}. An additional label {0: unlabeled points} marks points without ground truth and should not be used for training! In total over a billion points are provided. Please check out the reduced benchmark if your method is too computational demanding for the full data set.

We provide both training and test data as zipped ascii text files with format {x, y, z, intensity, r, g, b}. The ground truth is provided as single column ascii file, where the row ids of the class labeles and the points correspond. 7zip was used for compression and is available for both windows and linux.
