QGIS Vectors

[Mark]

Hello All

QGIS has native support for HEC-RAS meshes. It is fairly easy to display results that are grid based, but it would be pretty cool to have results as per the link

https://changelog.qgis.org/en/qgis/version/3.14/#featuremesh-coloring-mesh-vector-dataset-with-colo

The problem appears to be the absence of vector results in the .hdf mesh. Does anyone know of a solution. If not, will 5.1 include something similar or perhaps the option to export vector arrows?

Thanks

If you want the Vx and Vy, you have to check a box in HEC-RAS output options (HDF5 output) to have it store them in the *.hdf file.

There is an option in HEC-RAS Mapper to set create vector arrows or do particle tracing, but not a way to export the vectors themselves.

What I have done is used the data from the *.hdf and created the vectors in GIS.
