Once you have a cross section and the Z values along the cross section are pulled from the underlying DEM data, are those Z values typically edited within the stream where the DEM has a flat surface to get bathymetric heights? Or is there some source of terrain with the bathymetry for streams along with terrain surface heights?įinally, are the bank locations for each cross section typically specified manually, or is there some automatic way to calculate those based on the stream geometry. Are the cross-sections typically drawn by hand, or is there some automated way that cross sections could be placed along the stream path? We have noticed that the cross-sections for streams don't seem to have a consistent spacing or geometry. We are finally getting around to adding some HEC-RAS integration in to Global Mapper and were hoping for some customer input. Again, I would like to strongly reinforce the value of adding this toolset to your product. Please let me know if you'd like more info regarding this statement.
HEC HMS FOR MAC FOR FREE
As the *Geo* editors are already coded and available for free I'm fairly confident it would not be a significant challenge for your coders to retrofit them into Global Mapper.
HEC HMS FOR MAC SOFTWARE
I believe, and I expect that many would support this sentiment, that the inclusion of *Geo* editors for HEC-HMS and HEC-RAS in the Global Mapper software would actually improve your bottom line. The software packages are fairly simple and are accompanied by spatial data editors (HEC-GeoHMS and HEC-GeoRAS) however, the *Geo* applications are only really available as build-ins to ARC which, aside from being cumbersome and crashy, is also outrageously expensive.
HEC HMS FOR MAC DOWNLOAD
The Army Corps of Engineers developed various softwares including HEC-HMS and HEC-RAS which are free to download and widely used in the technical community by hydrologists and hydraulic engineers. I would like to reinforce the value of the toolset described by the previous posters. Such as creating flood inundation maps, depth plots, scour plots.
While this would be a great starting point, GlobalMapper has the potential to post process data that HEC-RAS creates. Since HEC-RAS is public software I think you can obtain the needed information for this file.
The only step remaining is creating the file ready to be imported into HEC-RAS. GlobalMapper is already setup to do all of those.
It is the primary software package used all over the nation for floodplain mapping related to FEMA and NFIP. HEC-RAS (Hydrologic Engineering Centers River Analysis System) put out by the US Army Corps is a freely available software package used for hydraulic modeling of rivers.
