Hi Daniele,
I'm sorry I made some confusion in my explanation.
Here's the output of the command on the shapefile.
In my configuration I have raster data on Azure, with a folder for each date,
containing some small files (about 2-3 dozens) that I want to put together in a
mosaic.
At the moment I'm working with a local GeoServer installation on my machine but
in
production I'll use a remote hosted GeoServer instance. I took a look at the
tutorial you linked but I don't think it fits my requirements. In production
there will be no data hosted locally because the files
are directly written on Azure, so I will not have the possibility to upload
local
data to the cloud. In addition, I would like to keep the configuration
as simple as possible and I didn't think a DB was also necessary.
Therefore in this configuration, with the cogs loaded on Azure and no local
data to
the GeoServer instance, is it not possible to configure a mosaic but only
single GeoTIFFs?
Thanks,
Nicola

Hi Nicola,
I'm not 100% sure to have fully understood your current configuration.
When you say:
Now I need to create image mosaic reading different cog files from a single
directory.
Are these files on a local directory or in a remote azure path?
If you have gdal utilities around, what is the output of a "ogrinfo -al
yourshapefile.shp"?
I think you are right and you are having an imagemosaic index based on
shapefile with locations referring local data on disk with paths relative to
the imageMosaic dir. (see the 655.tif granuleLocation which is not a COG Remote
URL)
For dynamic operations involving REST calls and imageMosaic index updates it's
better to have a DB based imageMosaic index.
You could setup a PostGIS DB and have the datastore properties referring to
that DB when doing the REST config.
Let us know if you have troubles in setting up imageMosaic on DB.
Note that there is also a tutorial to switch from an ImageMosaic based on local
files to an ImageMosaic with the very same files being COG files somewhere on
S3 or remote server.
https://docs.geoserver.org/latest/en/user/community/cog/update.html
So, if you already have local files as well as the same files on azure, you
might want to try that approach too which means:
- first configure an ImageMosaic based on datastore.properties with granules as
local files.
- Then update a few properties and the DB index to switch using COG remote
granules as reported on the tutorial
Please, let us know.

Daniele Romagnoli

Hi Daniele,
I'm sorry I didn't notice I didn't put the ML in cc.
I attached a text file with some logs obtained when requiring the layer.
I can see exceptions that were not visible without the developer logs:
java.lang.IllegalArgumentException: Illegal argument: "granuleLocation=657.tif".
I'm starting to think that the problem could be due to the creation of the
store/coverage. I didn't manage to create the storage without providing a
shapefile like in the cog mosaics tutorial. As a workaround, I put in the
configuration zip the .properties file (attached to this mail) and a shapefile
generated creating the image mosaic with the same raster files locally (which I
know isn't a correct solution).
Maybe I introduced some errors in these steps.
Thanks,
Nicola

Hi Nicola,
please keep the ML in CC so anyone can see the logs and eventually provide his
feedback and help you.
I would say let's start with getting the logs once you request a layer preview.
If we don't see anything wrong, we could step back trying to recreate the store
and see if some exception/problem gets reported but I suspect nothing occurred
at that point since you properly configured a layer.
Please, let us know.

Daniele Romagnoli

Hi Daniele,
which request do you want me to try and log? The store/coverage creation ones
or the log of the layer preview interface?
Thanks for the reply,

Hi Nicola,
do you have any GeoServer log showing something odd?
You might want to try to raise the logging level to GEOTOOLS_DEVELOPER and
repeat the request and check if there is any error or other type of exception
being reported.
You can share the log with us so I can take a look at that.
Please, let us know.

Daniele Romagnoli

Hi everyone,
I'm working with GeoServer and cloud-optimized geotiffs hosted on Azure.
I managed to create stores and layers using the cog
plugin<https://docs.geoserver.org/latest/en/user/community/cog/cog.html> with
single geotiff files. Now I need to create image mosaic reading different cog
files from a single directory. I tried to follow the image mosaic
guide<https://docs.geoserver.org/latest/en/user/community/cog/mosaic.html> for
cloud files and I managed to create the store and the coverage using the REST
calls shown in the tutorial.
The problem is that when I try to preview the coverage I can only see a blank
layer, and every pixel when clicked shows a GREY_INDEX value 0.
I can't understand what I'm doing wrong because the same file published as a
single geotiff works while inside a mosaic it does not. Any idea?
Thanks in advance,
Nicola
