GIS Technical Documents

The GIS Team at the Boise Aquatic Sciences Lab frequently puts together technical documents or ‘procedures’ on how to use ArcGIS for specific projects.  Attached are some that might be helpful to the general GIS user when modified to their needs.

These instructions refer to using ArcGIS and are PDF files that will open in a new window, unless otherwise stated. Please see our Lab Software Download Page for information on software needed to view downloads.

• Notes and Procedures for using TauDEM

• Create Geometric Network, Set Stream Flow Direction for Utility Network Analyst and Flip Arcs to Point Downstream

• Method for computing Stream Drainage density

• Computing Road Density using Spatial Analyst

• Computing Road Density per Watershed and Identifying Stream Crossings

• Attributing Points with other layers (Lines or Raster Values)

• Creating points from an excel file of XY coordinates

• Calculating the Shape Length or Shape Area in ArcMap

• Creating TauDEM Network and Generating a Stream Gradient Profile

• Deleting Island polygons from a Shapefile

• Using Linear Referencing to Create Segments 1000 meters Upstream from Points

• Generating Stream Gradient and Contributing Area using NHD lines in a Raster Environment

• Generating Stream Gradient and Contributing Area using NHD lines in a Vector Environment

• Routing a Stream Network and Adding Equal Interval Point Events

• Setting Flow Direction for TauDEM Streams or other Stream Layers

• Installing an ArcGIS Hardware Key (Forest Service only)
