资源简介:
This dataset contains information about waterfall locations and estimated waterfall heights on five of the main Hawaiian Islands including Kauai, Oahu, Maui, Molokai, and Hawaii. Initial spatial information was gathered from the National Hydrography Dataset (NHD), Geographic Names Information System (GNIS), the Hawaii Statewide GIS Program, and the World Waterfall Database. Where image quality permitted, the coordinates and spatial attributes from source data were used to verify and improve the quality of waterfall locations using Google Earth Pro (Google Inc. 2017)and the USGS HydroLink Tool. The HydroLink Tool was also used to link data to both the NHDPlusV2.1 and NHD High Resolution datasets by adding NHD addressing fields of reachcode and measure. Heights of falls were estimated, when possible, using elevation data in Google Earth Pro or from height data from the World Waterfall Database. This was a collaborative effort between University of Hawaii Manoa, Michigan State University and the U.S. Geological Survey.
