Curious as to what % of those GeoTIFFs were cloud optimized...

Cloud Optimized Geotiffs
The TIFF file format is a very old format, dating back to 1992, which is great for high-resolution, verbatim raster images. It’s still used a bit in high-end photography, but has really grown a second...

Pro tip: if you archive and/or distribute GeoTIFFs containing 16- or 32-bit data, these commands are magic:
--co COMPRESS=DEFLATE --co PREDICTOR=2 --co TILED=YES
1.77 *GB* to 55.8 *MB* (most of the dataset is blank, but still…)
--co COMPRESS=DEFLATE --co PREDICTOR=2 --co TILED=YES
1.77 *GB* to 55.8 *MB* (most of the dataset is blank, but still…)

As good a time as any to remind everyone (especially media) that the Earth Observatory publishes unlabeled, high-res images when they’re available:
science.nasa.gov/earth/earth-...
The link’s just buried at the bottom of story (and no more GeoTIFFs, AFAIK).

We just updated the #EarthEngine documentation for how best to create Cloud Optimized GeoTiffs (COG) for live reading from Google Cloud Storage (GCS).
When GDAL 3.11 is released, we will be able to add info on using the COG driver with INTERLEAVE=BAND.

Anyone familiar with time series animation in QGIS? I have a series of GeoTIFFs with valid (I think) timestamps in the metadata that aren’t recognized as timestamps. And the QGIS tool to automatically assign timestamps thinks a month is always 30 days. 🤷♂️
So I’m at something of a loss.
