  "description": "This data set contains a total of 73,031 landmarks. 10,433 landmarks were detected and extracted from 180 HiRISE browse images, and 62,598 landmarks were augmented from 10,433 original landmarks. For each original landmark, we cropped a square bounding box that includes the full extent of the landmark plus a 30-pixel margin to left, right, top and bottom. Each cropped landmark was resized to 227x227 pixels, and then was augmented to generate 6 additional landmarks using the following methods:\n\n1. 90 degrees clockwise rotation\n2. 180 degrees clockwise rotation\n3. 270 degrees clockwise rotation\n4. Horizontal flip\n5. Vertical flip\n6. Random brightness adjustment",
