Ensure close match to aerial imagery by editing the pre-smoothed feature class.

Utilize Cartography Tools -> Smooth Line tool -> BEZIER_INTERPOLATION.

Make sure all line editing is taking place on a GDB feature class.

Arc Hydro Tools are free with your ArcGIS software license. Or follow this link which takes to you the direct downloads. To avoid the jagged line appearance at large scales, my best guess is to: Follow this link to our Arc Hydro GeoNet Space. I'm then comparing the output shapes to ancillary surface water data and editing the raster-derived lines manually to add or subtract vertices, so they line up with 6" resolution aerial imagery. Shapefiles approximate a curve with multiple straight line segments.Īt the moment, I am deriving preliminary stream polylines from a 1 meter bare earth DEM (partially hydro-enforced) with the ArcHydro workflow above. Only feature classes are capable of true Bezier curves in between adjacent vertices. BEZIER appears better at capturing the far bends or oxbows in a meandering watercourse.Īdditionally, Esri help documentation highlights the difference between shapefiles and geodatabase feature classes when smoothing. PAEK is the default within the editing environment. and 1.ĪrcToolbox -> Cartography Tools -> Generalization -> Smooth Line tool grants the user the ability to leverage the PAEK or BEZIER INTERPOATION algorithm.

Although you can enter a value between 0 and 1, there does not appear to be any difference between 0.1, 0.2, 0.3, etc. The influence of the source 1 meter DEM becomes more apparent when zooming in.ĪrcGIS smooth tool (Advanced Editing toolbar) allows the user to specify a maximum allowable offset.

> Stream Seg.-> Drainage Line Processing) outputs a polyline that requires manual QA/QC to determine if lines are real and flowing appropriately. Spatial Analyst extensions is recommended.ĪrcInfo with the TIN extension is required.Has anyone found an effective ArcGIS 10.3.1 workflow for smoothing streamlines generated from ArcHydro.or hydrology in general?

HEC-RAS Version 5.0.4 should be available NITF for ArcGIS for Linux Server 10.1 SP1 Now available () NITF for ArcGIS for Linux Server lets you directly view and write NITF data within ArcGIS. HEC-RAS Version 5.0 contains the results mapping capabilities in HEC-GeoRAS Version 10.2, and HEC-RAS Version 5.0.4 will contain geometric preprocessing capabilities. HEC is developing the necessary GIS capabilities directly within HEC-RAS. Have been made available from the ESRI FTP site however, these newer versions have not been tested nor will they be supported by HEC.

HEC will no longer test and verify newer versions of HEC-GeoRAS that is compatible with versions of ArcGIS that are newer than Version 10.2.1. HEC-GeoRAS Version 10.2 is the last version that was tested and verified to be functional in ArcGIS 10.2.1Īnd is available from this webpage. The HEC-GeoRAS downloads available from this webpage were tested, verified, and are supported by HEC. Thorough understanding of river hydraulics to properly create and interpret GIS data sets. Users, however, must have experience modeling with HEC-RAS and have a GeoRAS extension is designed for users with limited geographic information systems (GIS) experience, knowledge of GIS is advantageous.

HEC-GeoRAS is a GIS extension that provides the user with a set of procedures, tools, and utilities for the preparation of GIS data for import into HEC-RAS and generation of GIS data from RAS output.
