SFR2 - Elevations from TIN's?

[Bruce Campbell]

Does the new version of GMS have the feature in the SFR2 package to get land surface altitudes - assigned to stream reaches from a TIN? The Drain and River packages have this capability which is very handy. I'm still using the 9.0 version.

It doesn't. I agree it would be a useful feature. We'll discuss it.

Hi Michael -- Thanks for the quick reply. Having this feature in the STR and SFR2 in GMS would make these two packages much more user friendly. Right now, I'm working on a model with about 8,800 stream reaches so it's not practical to assign them by hand. Is it possible to bring the elevation data into GMS associated with the stream arcs through the GIS module (importing a shapefile)? This would involve getting the elevation data together with the NHD (National Hydrologic Dataset) flowlines outside of GMS, somehow. I've got a good GIS guy and maybe he can figure it out.

Do you think this would work - not the GIS part (i'll figure that out) but if I can get the NHD flowlines and elevations together in a shapefile - would GMS put the elevation data associalted with the flowlines into a SFR2 map coverage in GMS?

The USGS folks that develop the NHD data would like to include land surface altitudes with the NHD but it hasn't happened, yet.

Just an update on this. It has been implemented in our development version and it will be available in GMS 10.0 (it may not be in the first beta release).
