Summary

This dataset provides point locations of wetlands in the channeled scablands of Washington State. It was created through object based image analysis of high resolution imagery from 2006 and 2009. Each wetland location has an associated surface water hydrograph constructed from spectral mixture analysis of Landsat satellite imagery (1983 – 2011). Hydrologic data is stored in an associated csv file and can be linked to the data through a unique identifier (Wetland_ID). Additionally, individual surface water hydrographs for wetlands, in jpeg format, can be linked to wetland location through the unique identifier.

Purpose

This data provides detailed hydrologic data on wetlands and can be used to determine seasonal and longterm patterns in wetland surface water dynamics. This dataset was primarily used to monitor historic wetland change and for future climate modeling.
