Free template maps and apps for your industry. If no layers are selected, a legend is added containing all applicable layers from the map contained in the default map frame. I'm not 100% certain how different the resultant surface would be from your original DEM, though you can be sure it'll work for creating stream networks, if exact height measures aren't vital. You could use your existing DEM to create height points and/or contours, then use the Topo to Raster tool to re-create a hydrologically correct DEM including your water network. If you are defining stream networks, you not only need to know the direction water flows from cell to cell but also how much water flows through a cell, or how many cells flow into another cell. To create the stream network, you must first calculate the flow direction and flow accumulation for each cell location. This map was created by uploading a data table with latitude and longitude coordinates and attributes about each field site to ArcGIS Online, and then embedded into this story map. Delineate the boundary of a catchment/contributing area using a Digital Elevation Model and a given point (a specific point for which we want to find the contributing/catchment area).
