Description
This dataset is generated from the information about the mosaics that make up the BD Ortho produced by IGN.
It is an aggregation of the “Mosaic” files available in the BD Ortho 5 m broadcast under Open License. The right-of-way with the same shooting date and time has been merged.
It makes it possible to know the freshness of the aerial images making up the comic Ortho, but also for example to calculate the position of the sun when shooting and therefore the orientations and lengths of the shadows carried or even other calculations on the shadows.
