GTOS (Ground Terrain in Outdoor Scenes), a first-of-its-kind in-scene material reflectance database, consists of over 30,000 images covering 40 classes of outdoor ground terrain under varying weather and lighting conditions. The 40 surface classes mostly have between 4 and 14 instances (samples of intra-class variability) and each instance is imaged under 19 viewing directions.
