Hi,
When using gdal raster info I have noted that in the "raster:bands"
section (with output format set to default json) the nodata value of
float rasters is always reported as "null". All attempts to change or
set the nodata value seem unable to fix this. It only happens with
float rasters - if you convert a float raster to int with
gdal_translate, nodata is correctly reported. If you convert it back
to float, it becomes null again. I've tried this on a few rasters and
it seems consistent. All were GTiff format.
This is a bug specific to the STAC relate part of JSON output. Will be
fixed per https://github.com/OSGeo/gdal/pull/13333
I was curious about this because I've been investigating an issue
where raster2pgsql is seemingly refusing to recognize and not write
empty tiles (as it should be without the -k flag). I was curious if
this could be a bug or some other occurrence whereby it's not
recognizing the nodata value of the raster properly, therefore leading
to always writing the full raster.
I know raster2pgsql specific questions aren't for here, I will make a
similar mail to the postgis-users mailing list soon, I was just giving
context.
Not sure about the raster2pgsql issue, but definitely not related to the
above bug.
