PIE LTER Water Network (2005), Plum Island Sound estuary, Massachusetts - Vector

Summary

Short name: 

WaterNetwork_2005_PlumIslandEstuary_vector_V1

Abstract: 

Fine scale DEM was generated by using Terrasolid’s TerraScan Lidar processing software, based on airborne LiDAR data collected on April 19th to 25th, 2005; then a toolbox ArcHydro in the software ArcGIS is used to extract stream network from the DEM data.

Methodology

Methods: 

The whole water network was generated using Arc Hydro package (http://resources.arcgis.com/en/communities/hydro/01vn0000000s000000.htm) in ArcGIS software.
We followed the procedure: (1) DEM Reconditioning; (2) Fill sinks; (3) Flow direction; (4) Flow accumulation; (5) Stream definition; (6) Stream segmentation. Additional 20 hours were spent on manual edition based on the latest fine-resolution 2015 image after we processed topographic data in Arc Hydro.
