[gdal-dev] STACIT and limit

[Michael Sumner]

this works for me, there are ten items in the filelist:

gdalinfo "STACIT:\"
https://earth-search.aws.element84.com/v1/search?collections=sentinel-2-c1-l2a&bbox=0,0,10,10&datetime=2023-01-01T00:00:00Z/2023-12-31T23:59:59Z\":asset=visual"
-oo MAX_ITEMS=10

and with 20 it's also fine, filelist of 20.

but, with MAX_ITEMS=40 there's the warning

Warning 1: Maximum number of items (1000) allowed to be retrieved has been
hit

and the result is SDS list split by CRS:

gdalinfo "STACIT:\"
https://earth-search.aws.element84.com/v1/search?collections=sentinel-2-c1-l2a&bbox=0,0,10,10&datetime=2023-01-01T00:00:00Z/2023-12-31T23:59:59Z\":asset=visual"
-oo MAX_ITEMS=40
Driver: VRT/Virtual Raster
Files: none associated
Size is 0, 0
Subdatasets:
  SUBDATASET_1_NAME=STACIT:"
https://earth-search.aws.element84.com/v1/search?collections=sentinel-2-c1-l2a&bbox=0,0,10,10&datetime=2023-01-01T00:00:00Z/2023-12-31T23:59:59Z
":asset=visual,crs=EPSG_32631
  SUBDATASET_1_DESC=Asset visual of
https://earth-search.aws.element84.com/v1/search?collections=sentinel-2-c1-l2a&bbox=0,0,10,10&datetime=2023-01-01T00:00:00Z/2023-12-31T23:59:59Z
in CRS EPSG:32631
  SUBDATASET_2_NAME=STACIT:"
https://earth-search.aws.element84.com/v1/search?collections=sentinel-2-c1-l2a&bbox=0,0,10,10&datetime=2023-01-01T00:00:00Z/2023-12-31T23:59:59Z
":asset=visual,crs=EPSG_32632
  SUBDATASET_2_DESC=Asset visual of
https://earth-search.aws.element84.com/v1/search?collections=sentinel-2-c1-l2a&bbox=0,0,10,10&datetime=2023-01-01T00:00:00Z/2023-12-31T23:59:59Z
in CRS EPSG:32632


Another case is this where there should be 4 TCI.tif items, but I only get
2 subdatasets (one for each CRS)

gdalinfo "STACIT:\"
https://earth-search.aws.element84.com/v1/search?collections=sentinel-2-c1-l2a&bbox=179,-17,180,-16&datetime=2023-01-01T00:00:00Z/2023-01-03T23:59:59Z\
":asset=visual"

It feels like something awry with the limit for the server, or the driver,
or maybe interacting.

But, I think it's reasonable expect to not get SDS listed when an asset is
specified?

Cheers, Mike
