skyfull-dolomites-rescue-v1

Rescue drone trajectory dataset over real Dolomites terrain (South Tyrol, Italy). Generated with Skyfull — a geo-scale simulation platform for physical intelligence.

What makes this different

No pixels. No camera. Pure XYZ coordinates.

The terrain is encoded as an implicit neural function (TerrainNet), not a texture or image. Every trajectory is a sequence of (lon, lat, alt_m) waypoints computed analytically, then used as supervised signal for a tiny policy MLP.

This is the same principle as LeRobot — collect → train → deploy — but the "lab" is a real Alpine mountain range and the "robot" is a rescue drone.

Quick start

import numpy as np
from huggingface_hub import hf_hub_download

episodes = np.load(hf_hub_download("Ethgar/skyfull-dolomites-rescue-v1", "episodes.npy", repo_type="dataset"))
victims  = np.load(hf_hub_download("Ethgar/skyfull-dolomites-rescue-v1", "victims.npy",  repo_type="dataset"))

print(episodes.shape)   # (10000, 40, 3)
print(victims.shape)    # (10000, 3)
