GeoServer NetCDF plugin, read grid_mapping_name="vertical_perspective"

Question

I am currently using NetCDF plugin for GeoServer. I would like to know if there is any solution to be able to read a NetCDF with the attribute grid_mapping_name="vertical_perspective".

While debugging I found out in org.geotools.coverage.io.netcdf.crs.NetCDFProjection, that only few projections are currently supported (code available here : https://github.com/geotools/geotools/blob/fe5eac60bcbaabc50af40b75de7bae6f320f09e9/modules/plugin/coverage-multidim/netcdf/src/main/java/org/geotools/coverage/io/netcdf/crs/NetCDFProjection.java#L236)

So I would like to know if any of you dealt with "vertical_perspective" projection while using Geoserver NetCDF plugin? And how did you manage to make it work? Maybe one solution is to override NetCDFProjection class and add "vertical_perspective" projection?

Answer 1

GeoTools does not support a projection named "vertical perspective". The first step would be to add support for it, by writing the necessary code in the gt-referencing module, and then to wire it up in the gt-netcdf module.

In case you or someone you know can do it, contribution rules are here, otherwise, there are companies that can do it on your behalf.
