Trouble rendering Global UGRID mesh #84

Open rsignell-usgs opened 7 years ago

rsignell-usgs commented 7 years ago

I'm having trouble getting EDAL/ncWMS2 to render this global UGRID dataset correctly: OPeNDAP endpoint: http://www.smast.umassd.edu:8080/thredds/dodsC/FVCOM/NECOFS/Forecasts/NECOFS_FVCOM_OCEAN_GLOBAL_FORECAST.nc.html ncWMS2 endpoint here: http://gamone.whoi.edu/ncWMS/

@edal-java team, can you tell if the problem in on my end or yours?

@rsignell-usgs - Looks like it's on our end. The issue is that we try and create a bounding polygon for a mesh, along with nested polygons in the case where there are holes in the mesh. However, for a global field the bounding polygons are actually the inside of landmasses. This is then further complicated by the fact that grid cells may cross the date line.

I'll continue to look for a solution as and when I get time, but it's far from a straightforward fix...

@guygriffiths, okay, thanks for taking a look and scoping the problem.

@yosoyjay and @kwilcox, here's another one that might be a candidate for NFWF work?

I'm quite enjoying the abstract images that are produced and going to label this as a feature :wink:
