org.n52.wps.ags.spatialanalyst.hydrology.flowlength FlowLength_sa Calculates distance or weighted distance along a flow path. Uses ArcObjects library - Spatial Analyst in:flow_direction_raster in flow direction raster The input raster that records the direction of flow out of each cell. This can be created with the Flow Direction function. application/img application/GeoTIFF application/img in_weight_raster in weight raster The weight to be assigned to each cell. If no {in_weight_raster} is specified, a default weight of one will be applied to each cell. For each cell in the output raster, the result will be the number of cells that flow into it. application/img application/GeoTIFF application/img direction_measurement direction measurement The direction of measurement along the flow path. DOWNSTREAM — Calculates the downslope distance along the flow path, from each cell to a sink or outlet on the edge of the raster. UPSTREAM — Calculates the longest upslope distance along the flow path, from each cell to the top of the drainage divide. DOWNSTREAM UPSTREAM

out_raster out raster The output raster that shows for each cell the upstream or downstream distance along a flow path. application/img application/GeoTIFF application/img
