I've figured out how to do what I wanted using the netcdf-java library directly: https://docs.unidata.ucar.edu/netcdf-java

I can access values in the 1st band, but have not found a way to access values in other bands. I have tested with GeoTools 25.1 and 26-SNAPSHOT and used this documentation: https://docs.geotools.org/stable/userguide/library/coverage/multidim.html#netcdf I tried added the following to the Indexer XML file that gets written in the directory with the other files: <multipleBandsDimensions> <multipleBandsDimension> <name>data</name> <bandsNames>Band 1,Band 2</bandsNames> </multipleBandsDimension> </multipleBandsDimensions> I've tried adding this in the section with the coverage and at levels outside and moving this file alongside the NetCDF file I am trying to read, but had no success so far... There is a WARNING in the output: WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by org.geotools.image.ImageWorker (file:/C:/Users/agdtu/.m2/repository/org/geotools/gt-coverage/26-SNAPSHOT/gt-coverage-26-SNAPSHOT.jar) to constructor com.sun.imageio.plugins.jpeg.JPEGImageWriterSpi() WARNING: Please consider reporting this to the maintainers of org.geotools.image.ImageWorker WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release Jul 07, 2021 5:56:49 PM org.geotools.image.ImageWorker <clinit> Does anyone have any advice? Thanks, Andy
