Joe,Your sample is correct, and the documentation says that you can remove groups.
But the library it's no implementing it. It's a feature missing. @John, the code for removing groups is missing on the corresponding method: https://github.com/Unidata/thredds/blob/master/cdm/src/main/java/ucar/nc2/ncml/NcMLReader.java#L1422-1454 Regards Antonio -- Antonio S.

Thanks, Antonio! I tried union and it looks promising. However, I got another issue. I need to remove some conflicting objects (groups, dimensions, and variables) from data.nc first to make union work. How can I remove a group and all objects under the group recursively in NcML? I tried something like: <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2"; location="MOD29.A2013196.1250.005.2013196195940.hdf"> <group name="MOD_Swath_Sea_Ice"> <remove name="Geolocation_Fields" type="group" /> </group> </netcdf> for MODIS product at [1] but it doesn't remove group and its objects under it. My ultimate goal is to merge Geolocation_Fields from [2] with [1] via NcML and visualize [1] with IDV/Panoply.

Joe Lee escribió:Hi, I'm wondering if the following composition is possible in NcML. I read tutorial on the web but I could not find a solution yet. Let's assume that data.nc has no coordinate variables but geo.nc has. I'd like to create a data.ncml like below to import coordinate variables from a separate NetCDF file (i.e., geo.nc) so that I can visualize data variables in data.nc with IDV by opening data.ncml. <netcdf location="data.nc"> <!-- import geo-location data from external file. --> <variable name="Latitude" location="geo.nc"> <variable name="Longitude" location="geo.nc"> </netcdf> Is the above scenario possible with NcML via netcdf-java? If so, what NcML tag & attribute should I use to import variables from external files?
