Mono Lake Surface Water Extent Landsat8 Data

Overview

Aquatic scientists and water resource managers require information on the dynamics of surface water extent. Surface water extent is modulated by weather and climate, stream network hydrology, and geological processes such as isostatic rebound. Land use, ecosystem and services, and water management are also impacted by changes in surface water extent.

This dataset contains such surface water extent information for the Mono Lake. It documents the existence and condition of surface water in the area from 2013-04-18 to 2019-12-31 in a spatial resolution of 30 meters.

This dataset is derived from the Landsat 8 Dynamic Surface Water Extent product from the USGS/NASA Landsat Program. The original data is distributed in raster format (GeoTIFF) and has a per-pixel 30-meter spatial resolution. It was processed (by re-projection, filtering, etc.) and converted into the parquet format to make it easily consumable in ML/AI applications.

This data can be used to determine the lake boundary, to compute the area of the lake from the boundary, and to generate a time-series of the lake water extent and condition to monitor how the lake is changing over the time.
