Annual Sentinel-1 coherence and backscatter composites of Switzerland's glaciers.
One item per (MGRS square, year), each carrying twelve single-band
Cloud-Optimized GeoTIFFs on the 10 km MGRS grid at 10 m grid spacing, in that
square's own UTM zone. Agents: read AGENTS.md.
The asset key is the filename stem. Dates are in the item properties and the GeoTIFF tags.
Query the item mirror rather than walking the tree. items.parquet holds every
item of every year, so one range request replaces one HTTP fetch per tile:
The item JSON under each year sub-catalog stays the normative representation; the mirror is a derived copy of it.
rtc_* is linear power, not decibels. Convert with 10*log10(x), which
the collection's renders block declares.
*_qa_cqm is a linear ratio. It is a weighted average of the observations' local resolution
and does not carry a unit. For visualization, convert to decibels with 10*log10(x).
