Sentinel-2 geolocation

This geolocation project contains descriptors for Sentinel-2 missions.

Overview

This package declares geolocation properties for sentinel-2 products:

• footprint: geometric extent on sentinel-2:product_user resolved from the metadata MTD_MSIL*.xml Global_Footprint.
• band-extent: aggregates on sentinel-2:product_user_level-1c (GRANULE//IMG_DATA/_B01.jp2) and sentinel-2:product_user_level-2a (GRANULE//IMG_DATA/R60m/_B01_60m.jp2).

Python packaging (pip)

Since drb-testbench#40 phase 1, this repo ships a Python package, drbx-kb-geolocation-sentinel-2, mirroring the drbx-kb-topics-* pattern: the package ships geolocation descriptor TTLs and exposes them through the drb core loader; drb core >= 2.9 merges every file into the shared topic graph at resolver import.

pip install drbx-kb-geolocation-sentinel-2

Consumer example (using the drb-addon-geolocation add-on):

from drb import resolver
from drb_addon_geolocation import GeolocationAddon

node = resolver.create("s3://bucket/sentinel-2-product.zip")
addon = GeolocationAddon()
addon.apply(node)
# node["footprint"], node["band-extent"], ... now available
