Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

Abstract

A Normalized Difference Water Index (NDWI) is an indicator of open water on the landscape. It was developed at a 10 meter resolution using Google Earth Engine Sentinel-2 satellite imagery. For more information on the Sentinel-2 imagery: https://explorer.earthengine.google.com/#detail/COPERNICUS%2FS2 Script used to derive data: https://code.earthengine.google.com/774e4ed152e4651971dc6e9456998d17 Methods: This is a composite image where each pixel is selected based on the NDWI function (Green-NIR/Green+NIR). This composite thus represents the highest NDWI for every pixel for that location captured by Sentinel-2.

Description

This data layer is an individual GeoTIFF files with a resolution of 10 meters.
