Re: RAS Mapper - Map Polyline boundary not creating
Not sure why it is not working tried create the map on my current project and it worked. You do need to highlight and "Compute/Update Stored Maps" but I was able to export as a shp or KMZ file.
While I tried the process with your files I ran into the same problem that you are experiencing. Not sure why my files are working and yours are not but a workaround might be to export the Depth or WSE data into AcrGIS and use the "Raster Domain" tool.
I've helped a colleague who was having the same issue. I couldn't find any issue with the model but noticed that their terrain surface has a odd cell resolution of something like 6.562 so I resampled to a 5x5 and ran the model against that surface and it worked fine.
Even if your surface doesn't have a odd cell resolution you might try resampling it to see if that clears it up. Most likely it is terrain related I'm betting.
Re: Re: RAS Mapper - Map Polyline boundary not creating
I am having the same issue. I resampled my terrain in GIS and still did not solve it. Exporting to a shapefile works in v4.1.0 but not v.5.0.3. When I exported in v.4.1.0, the WSE was somewhat pixelated. Also, using the Raster Domain tool created a very pixelated boundary as well. The shapefile in v4.1.0 was much better.
Any fix to getting this to work in the new version? RAS mapper makes it too easy to map the floodplain but yet impossible to export that out to GIS.
I think I figured it out and now have it working.
My 2D area boundary condition for the outlet had more that 2 nodes, once I altered it to only have two nodes I can now create a polyline and export to SHP file.
