IGNF/FRACTAL-IRGB

This repo contains the orthoimageries used to colorize point clouds in the FRACTAL semantic segmentation dataset.

They are provided as is, in their original size (50 x 50 m), spatial resolution (0.2 m, i.e. 250 x 250 pixels) and band order (near-infrared, red, green, blue).

They might be used for quick visual inspections of the FRACTAL's point clouds, or for more advanced use such as multimodal (2D-3D) deep learning training.

Note:

• The files are ordered by filename. Inspecting a single zip archive is therefore not representative of the whole dataset.
• The band order does not play nice with standard image softwares. Consider reordering band order and disabling the use of transparency in a GIS software like QGis.
