Matt and I were recently chatting about this (I was thinking winds), and I'd love to see this as more generalized Xpublish plugin.
Maybe we hack something up during the code sprint?
Ah, yes! Would totally make sense as a general xpublish plugin so it can be used elsewhere.
Would it make more sense to move this discussion to https://github.com/orgs/xpublish-community/discussions?
Ya, I think it's probably worth considering them as a whole new type of plugins.
While there is a way to make them with the existing dataset providers, that may not work as soon as folks get creative and replace them (like Matt's subsetting plugin), so we probably want to make them explicit so they can be reused.
@srstsavage So we have to support virtual variables in a few different ways already and its not fully fleshed out, but here is a quick overview:
I would like to see the extension behavior be xpublish native as well so i agree with alex
General discussion over https://github.com/orgs/xpublish-community/discussions/25
It would be great if xreds could create virtual variables from scalar component variables based on standard names (e.g.
eastward_sea_water_velocity
andnorthward_sea_water_velocity
are detected and a virtual vector variablesea_water_velocity
with magnitude and direction is created, and rendered tiles represent magnitude as grid color and direction as an arrow or barb, etc).Some ncWMS code detecting vectors:

Any thoughts on the desirability of this behavior, or how it should be implemented? Core behavior, or in a plugin or extension?
