Data and Tools

Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

L7 Irish Cloud Validation Masks

The scenes in this dataset were originally selected by Richard Irish, NASA-GSFC, and were derived manually from Landsat Enhanced Thematic Mapper Plus (ETM+) Level 1G scenes by Pat Scaramuzza and Michelle Bouchard at the USGS EROS Center. Its purpose is train and validate cloud masking algorithms. Each product is provided as a thematic raster, and includes the classes of “cloud”, “thin cloud...

Gulf Coast Vulnerability Assessment

The Gulf Coast Vulnerability Assessment (GCVA) used an expert opinion approach to qualitatively assess the vulnerability of four ecosystems: mangrove, oyster reef, tidal emergent marsh, and barrier islands, and a suite of wildlife species that depend on them. More than 50 individuals participated in the completion of the GCVA, facilitated via Ecosystem and Species Expert Teams. The GCVA made...

Mean of the Top Ten Percent of NDVI Values in the Yuma Proving Ground during Monsoon Season, 1986-2011

This study uses growth in vegetation during the monsoon season measured from LANDSAT imagery as a proxy for measured rainfall. NDVI values from 26 years of pre- and post-monsoon season Landsat imagery were derived across Yuma Proving Ground (YPG) in southwestern Arizona, USA. The LANDSAT imagery (1986-2011) was downloaded from USGS’s GlobeVis website (...
