[gdal-dev] Utilisation de Planetary Computer

[Loïc Lozac'h]

Bonjour,

Est-il possible d'utiliser la signature de la librairie python 
Planetary_Computer pour lire des COG depuis le catalogue STAC Microsoft ?

J'ai essayé plusieurs méthode en utilisant /vsicurl/ mais les extended 
filenames associé à la signature ne sont pas reconnu.

Est-il possible de lire ces données à la manière de RasterIO ?

J'utilise gdal version 3.5.2

code python en erreur :

vsistr= "/vsicurl?pc_url_signing=yes&pc_collection=sentinel-2-l2a&url="
red_href= vsistr+ planetary_computer.sign(item).assets["B04"].href
cogtif= gdal.Open( red_href)

response :

code python ok :

withfiona.open(shp, "r") asshapefile:
shapes= [feature["geometry"] forfeatureinshapefile]
withrasterio.open(planetary_computer.sign(item).assets["B04"].href ) asds:
out_image, out_transform= rasterio.mask.mask(ds, shapes, crop=True)
out_meta= ds.meta
out_meta.update({"driver": "GTiff",
"height": out_image.shape[1],
"width": out_image.shape[2],
"transform": out_transform})
withrasterio.open(out, "w", **out_meta) asdest:
dest.write(out_image)

Merci pour vos réponses

Bien cordialement,

Loïc
