Description

The West Branch Susquehanna River is a valuable resource to the towns it flows through. With funding from Susquehanna Greenway Partnership, Clinton County Commissioner’s Office, and Anadarko Petroleum Corporation, Lock Haven University’s Water and Soil Resources Lab created an interactive online navigational map that spans from Renovo to Love Creek, PA. The project began in September 2014 as a senior research initiative and has expanded to a community effort following the designation of Lock Haven as a River Town by the Susquehanna Greenway Partnership in 2015 to create a navigational map of the river for boaters and outdoor enthusiasts. The map covered 48 river-miles illustrating water depths, public access points, parks, and landmarks along the river. The water depths, geographic coordinates, and images of land and river features were collected and analyzed using IDW method in ArcGIS software to prepare a navigational map, which was then uploaded onto an online server to make the map available to the public as an interactive online navigational map. Water depths for over 2,000 points were collected using the Speedtech Depthmate Portable Sounder and the coordinates were recorded with the Garmin etrex 30 GPS. The data points were entered into Excel, and were exported to ArcMap as a shapefile. Using the Spatial Analyst Extension, interpolation of the water depth data was done using the Inverse Distance Weighted (IDW) method as a raster file, which was converted into a polygon shapefile to be uploaded onto ArcGIS Online. This process was done using the From Raster to Point tool in the Conversion Toolbox to create a point shapefile, which was then converted into a polygon shapefile by creating Thiessan Polygons using the Proximity Tool found in the Analysis Toolbox. The polygons were then grouped based on the water depths assigned to them and were dissolved to create continuous polygons showing variations in water depths along the entire stretch of the navigational map.
