How to browse a fourth dimension that does not correspond to the Coordinate Axis Types? #101
Description
We are using WMS through THREDDS and have the following issue: our datasets have 4D-arrays of which the fourth dimension represents a discrete axis (‘entity’) with a character-based multidimensional coordinate variable (2D). Is there any way that ncWMS recognizes this fourth dimension and reads the character-based coordinate variable (like Panoply)? Our aim would be to have a GetMap request where we can browse the fourth dimension with a query using something similar to dim_entity=’lupus lupus’. An example dataset can be downloaded here: https://portal.geobon.org/ebv-detail?id=1
If that is not possible, is there a way to get a fourth dimension recognized by ncWMS (with an integer/float-based 1D coordinate variable) that is not height, pressure etc? We currently have to add a Coordinate Axis Type to avoid a ‘No grids found in underlying NetCDF dataset’ error. This leads to GetMap request with a query including e.g., elevation=1. In this case we would like to browse the fourth dimension with a query using something similar to dim_entity=1.
We appreciate any hints from you, knowing that you are currently not actively maintaining the ncWMS. Thanks for your help in advance!
