HEC-RAS 5.0 now provides a tool for quickly re-projecting model geometry within RAS. It is accessible from the main RAS interface under the Options menu…Convert Horizontal Coordinate Systems.
From this window, the user must select the Current Project Spatial Reference System and the Destination Project Spatial Reference System by loading the appropriate projection file (*.prj) for each. Do not confuse this file type with an HEC-RAS project file (also *.prj). Once the projection files are loaded, click OK.
A warning window will appear alerting you that running this tool will automatically save the data to disk. If you do not wish to overwrite your existing RAS project files, click cancel, save the project as a new name, and convert the duplicate project. Otherwise, click OK.
