Note: Determine the location of the pour point on the map using the flow accumulation raster layer as reference. If the input raster or feature pour point data is a point feature class, it will be converted to a raster internally for processing. Since I need to do this process ~250 times, I'm greatly interested in finding a more efficient method. ArcGIS Hydrology Tools Overview REM402 Understanding of how water flows across an area and how changes in that area may affect the flow GIS Hydrology • The concepts and key terms regarding drainage systems and surface processes • Extract hd l ihydrologic if iinformation from a di i ldigital Snap distance illustration (to delineate the contribution area of the stream crossing, a snap distance is required in finding the point having the highest accumulated flow). The mapping platform for your organization, Free template maps and apps for your industry.

I’ve recently starting scripting ArcGIS using Python as part of one of my academic projects (about which I’ll post more later) and needed to be able to snap points to polylines – that is, move points so that they lie on the nearest polyline. Maximum distance, in map units, to search for a cell of higher accumulated flow. from arcgis.gis import GIS from datetime import datetime as dt from arcgis.raster.functions.gbl import flow_direction, sink, fill, flow_accumulation, snap_pour_point, watershed from arcgis.raster.functions import slope, raster_calculator, con from arcgis.raster.analytics import convert_feature_to_raster Its current status is snapping pour points, but it has been doing this very slowly for the last 20 minutes. Using a point further downstream would create a watershed for the entire lake, including all regions that drain into the lake. In this example, the input is Pour_point. Maximale Entfernung (in Karteneinheiten), in der nach einer Zelle mit höherer Abflussakkumulation gesucht werden soll.

Dear all, I'm a new user on ARCINFO workstation. • Try several snap distances to avoid having all points go the same location (snap distance to large) or miss the stream network completely (snap distance too small). If the input raster or feature pour point data is a point feature class, it will be converted to a raster internally for processing. Wenn das Abflusspunkt-Dataset ein Raster ist, verwenden Sie "Wert". b. Using a point further downstream would create a watershed for the entire lake, including all regions that drain into the lake. # flow accumulation within a specified distance. If the input raster or feature pour point data is a point feature class, it will be converted to a raster internally for processing. Basically, the steps to create the Catchment area on ArcGIS are the following: Create DEM; Fill DEM; Create Flow Direction; Flow Accumulation; Create Pour points; Snap pour points; Create Watershed; Step 1. The Snap Pour Point tool is used to ensure the selection of points of high accumulated flow when delineating drainage basins using the Watershed tool. • Snap pour points to the highest point of flow accumulation near them.
