Flow length tool gis
WebThis section will describe ArcGIS 's hydrologic analysis tools. These include tools as watershed delineation, flow accumulation, and flow length. All of the hydrologic tools in ArcGIS are available only after enabling the Spatial Analyst Extension. The hydrological tools are accessed through ArcToobox. WebThe result of Flow Accumulation is a raster of accumulated flow to each cell, as determined by accumulating the weight for all cells that flow into each downslope cell. The Flow Accumulation tool supports three flow …

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 ...
