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

The minimum area used in the thinning algorithm to eliminate small, nonmain hydro polygons. The tool will write stream order values to an ORD field in Output Hydro Line Feature Class and Output Hydro Polygon Feature Class.

Utilize Cartography Tools -> Smooth Line tool -> BEZIER_INTERPOLATION The tool will thin hydro features that have a stream order value less than this number.

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

To avoid the jagged line appearance at large scales, my best guess is to: 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.ДЄt 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.ДЄdditionally, Esri help documentation highlights the difference between shapefiles and geodatabase feature classes when smoothing. PAEK is the default within the editing environment. and 1.ДЄrcToolbox -> 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.ДЄrcGIS 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.

You can apply a selection set or definition query to Input Area of Interest Features but not to Input Hydro Features.Has anyone found an effective ArcGIS 10.3.1 workflow for smoothing streamlines generated from ArcHydro.or hydrology in general? The Input Area of Interest Features parameter defines map extents. The ORD field contains stream order values for each input hydro feature. This tool will add a LONG field called ORD to the Output Hydro Line Feature Class and Output Hydro Polygon Feature Class. This tool will display an error if you add a feature class that does not belong to a feature dataset. All input feature classes must be inside the same featureДataset as topology is used to build a stream network. Input Hydro Features must reside within the same feature dataset. Polylines in Input Hydro Features should be split at intersections to ensure correct order value assignment. The direction in which polylines in Input Hydro Features are digitized should be the same as flow direction.

Input Hydro Features must be polyline or polygon features. е›і Stream network before and after using the Thin Hydro Features tool дЅїз”Ёжі• The algorithm removes less significant hydro features based on the number of tributaries. The Arc Hydro Toolset is a suite of tools which facilitate the creation, manipulation.

The generalized versions are produced using a stream order algorithm. Most people looking for Arc hydro tools 10.2 downloaded: HEC-GeoHMS. The following stand-alone script demonstrates how to use the Hydro Centerline tool. The minimum hydro order or stream order value used to eliminate hydro features.

Generalizes input hydrographic stream data into two feature classes: one for hydro polyline features and one for hydro polygon features.
