ECLAIR

ECLAIR (Extended Classification of Lidar for AI Recognition), a new outdoor large-scale aerial LiDAR dataset designed specifically for advancing research in point cloud semantic segmentation. As the most extensive and diverse collection of its kind to date, the dataset covers a total area of 10km2 with close to 600 million points and features eleven distinct object categories. To guarantee the dataset's quality and utility, we have thoroughly curated the point labels through an internal team of experts, ensuring accuracy and consistency in semantic labeling. The dataset is engineered to move forward the fields of 3D urban modeling, scene understanding, and utility infrastructure management by presenting new challenges and potential applications.

Annotations:

• Ground (2) : All points representing the Earth’s surface, including, soil, pavement, roads, and the bottom of water bodies.
• Vegetation (3) : All points representing organic plant life, ranging from trees, low shrubs, and tall grass of all heights.
• Buildings (4) : Man-made structures characterized by roofs and walls, encompassing houses, factories, and sheds.
• Noise (5) : Sporadic points suspended in air or underground.
• Transmission Wires (6) : High-voltage wires for long-distance transmission from power plants to substations. Either directly connected to transmission towers or poles. Also includes transmission ground wires.
• Distribution Wires (7) : Lower-voltage overhead distribution wires distributing electricity from substation to end users. Includes span guy wires and communication wires.
• Poles (8) : Utility poles used to support different types of wires or electroliers. These can include poles with either transmission or distribution wires. Down guy wires, crossarms and transformers are also included in this class.
• Transmission Towers (9) : Large structures supporting transmission wires with the distinct characterisation of steel lattices and cross beams.
• Fence (10) : Barriers, railing, or other upright structure, typically of wood or wire, enclosing an area of ground.
• Vehicle (11) : All wheeled vehicles that can be driven.
• Unassigned (1) : This category serves as a catch-all for non-subject points. Anything that is not on the class list is classified as Unassigned. These include wooden pallets, trash, structures not large or strong enough to put under buildings (tents, boulders, etc.), and house antennas.
