Catalog explorer (no network)¶

Browse the bundled Sentinel Hub two-layer catalog — curated collections and the evalscript recipe library — entirely offline. No credentials or network needed.

In [ ]:

from earthlens.sentinel_hub import Catalog, read_evalscript

cat = Catalog()
print('collections:', sorted(cat.datasets))
print('recipes:', len(cat.recipes))

from earthlens.sentinel_hub import Catalog, read_evalscript cat = Catalog() print('collections:', sorted(cat.datasets)) print('recipes:', len(cat.recipes))

Collections and their DataCollection binding¶

In [ ]:

for key in sorted(cat.datasets):
    col = cat.get_collection(key)
    print(f'{key:18s} -> {col}, default bands {col.default_bands}')

for key in sorted(cat.datasets): col = cat.get_collection(key) print(f'{key:18s} -> {col}, default bands {col.default_bands}')

Recipes (render vs Statistical dataMask variants)¶

In [ ]:

for key in sorted(cat.recipes):
    r = cat.get_recipe(key)
    print(f'{key:30s} {r.kind:6s} {r.evalscript}')

for key in sorted(cat.recipes): r = cat.get_recipe(key) print(f'{key:30s} {r.kind:6s} {r.evalscript}')

Resolve a recipe and read its evalscript¶

In [ ]:

resolved = cat.resolve('sentinel-2-l2a-ndvi')
print(resolved, '|', resolved.evalscript)
print(read_evalscript(resolved.evalscript))

resolved = cat.resolve('sentinel-2-l2a-ndvi') print(resolved, '|', resolved.evalscript) print(read_evalscript(resolved.evalscript))
