Adding 4d netCDF Raster Data Source into GeoServer

Question

I ́m using GeoServer 2.20.1 with the netCDF plugin (geoserver-2.20.1-netcdf-plugin.zip) on a Tomcat 9 locally on my Mac (localhost:8080).

I ́m trying to add a 4d netcdf file structure (filename: junker_v1.nc) into geoserver, but I ́m getting always the error:

"Could not list layers for this store, an error occurred retrieving them: Failed to create reader from file"

Screenshot error message

The error logs in geoserver are the following:

2022年01月20日 17:34:23,310 INFO [org.geoserver.web] - Getting list of coverages for saved store file:data/netCDF/junker_v1.nc

I have followed the tutorial: https://geoserver.geo-solutions.it/multidim/multidim/netcdf/netcdf_config.html#netcdf

Does anybody know why the error occur? The error logs are not really clear for me, but it seems geoserver has problems to handle the 4th dimension.

I tried the same with a netcdf structure in 3d and it works like a charm - geoserver could list the layers.

Answer 1

Looking at the stack trace, there is some issue setting up the variables.

While I cannot be sure, the likely cause is that your NetCDF is not copliant with the COARDS convention, a requirement for GeoServer to actually make sense of the contents.

See also: https://docs.geoserver.org/stable/en/user/extensions/netcdf/netcdf.html#notes-on-supported-netcdfs

It may be possible to make GeoServer read that NetCDF anyways, but it's likely going to require some development.
