WebThis tutorial will move to Esri Academy in early 2024. Learn more about this change. ... The next step of the task uses the Flow Length tool. While this tool, as its name suggests, normally calculates flow length, it has an optional parameter to include a weight raster. When a weight raster is included, the tool calculates flow time instead.

WebThe hydrologic modeling tools in the ArcGIS Spatial Analyst extension toolbox provide methods for describing the physical components of a surface. The hydrologic tools allow you to identify sinks, determine flow direction, calculate flow accumulation, delineate watersheds, and create stream networks. ... Using the Flow Length tool, the length ... WebI haven't used any other layers to weight the output, and I think my flow direction layer is accurate. I'm using the NASA SRTM elevation data, which has 1 arc-second (~30 m) cells. In Arc, the cell dimensions are listed as (0.00027777778, 0.00027777778), which I assume is in degrees. I understand the idea of the flow accumulation tool, I just ...
WebHORIZONTAL —The flow distance calculations represent the horizontal component of flow distance, following the flow path, from each cell in the domain to cell (s) on the stream into which they flow. The input flow direction raster can be of type D8, Multi Flow Direction (MFD) or D-Infinity (DINF). D8 —The input flow direction raster is of ... WebIn the older (ArcView) version, this command was available as a tool on the Hydro menu, but in ArcGIS, it is only available as a raster calculator command. ... For the first hour, your query should be this: ( [flow_length] <= 3600). This assumes that "flow_length" is the grid that contains the Flow Lengths.
