Extract mesh and WSEL to GIS

[mike.bannister]

Hello. I’m trying to extract the 2D mesh to gis as a series of polygons, one per cell, and then assign water surface elevations to each cell for visualization and reporting needs. I’m striking out with google and the documentation. I’ve also looked at the hdf5 geometry file and think i can create the cells from there, but wanted to verify there wasn’t an easier route before doing this the hard way. Example desired output is below (from a SMS/SRH-2D model), but I would like to label elevations in addition to colors, so a raster wouldn’t be the best. Any suggestions?

Thank you,

Mike

You can export out the mesh as polygons in Mapper.

Once this is done you could do a zonal statistic in ArcGIS to extract the wse for each polygon.

Thank you Cameron, that was the motivation I needed. For anyone else reading this, to export the mesh to a shapefile, right click 2D Flow Areas under Geometries -> Geometry, then click Export Layer -> Create Polygon Shapefile for 2D Cells as shown below.

SMS can also read HEC-RAS models now so your could follow the same procedure you used for SRH-2D
