What is stream to feature in ArcGIS?
The algorithm used by the Stream to Feature tool is designed primarily for vectorization of stream networks or any other raster representing a raster linear network for which directionality is known. The tool is optimized to use a direction raster to aid in vectorizing intersecting and adjacent cells.
How do you do a hydrology analysis?
Hydrological analysis is based on a digital elevation model (DEM) raster data to establish a water system model, which is used to study the hydrological characteristics and simulation of surface hydrological process, and make a forecast for the surface hydrological situation in the future.
How is the flow accumulation tool used in ArcGIS Pro?
The results of the Flow Accumulation tool can be used to create a raster stream network by applying a threshold value to select cells with a high accumulated flow. For example, cells that have more than 100 cells flowing into them are used to define the stream network.
How are stream networks identified in ArcGIS Pro?
Stream networks can be delineated from a digital elevation model (DEM) using the output from the Flow Accumulation tool. Flow accumulation in its simplest form is the number of upslope cells that flow into each cell.
Can a stream to feature be used on a raster?
Stream to Feature should not be used on a raster in which there are few adjacent cells of the same value. The direction of the output features will point downstream. See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.
When to use stream link and stream to feature?
The resulting stream network can be used in Stream Link and Stream to Feature. There should be contiguous features with the same value, such as the results of the Stream Order or Stream Link tool. Stream to Feature should not be used on a raster in which there are few adjacent cells of the same value.
