Description
GHISACONUS V001 provides hyperspectral signatures for five major U.S. crops across seven agroecological zones. The United States Geological Survey (USGS) compiled this library using EO-1 Hyperion satellite data from 2008 to 2015, referencing USDA crop layers and University of Wisconsin-Madison growth calendars. It includes spectral data, geographic coordinates, crop type, growth stage, and agroecological zone labels for crops like winter wheat, rice, corn, soybeans, and cotton.
Use Cases
Train crop type classification models based on hyperspectral signatures and crop type labels.
Analyze spectral changes across crop growth stages based on the six provided phenological stages.
Develop models for agroecological zone-specific crop monitoring using the seven AEZ classifications.
Validate satellite-derived agricultural indices using ground-referenced spectral libraries.
Strengths
Covers five major crops representing approximately 65% of global cropland area.
Includes data across six distinct crop growth stages, from emergence to harvest.
Spatial coverage spans seven agroecological zones across the conterminous United States.
Data collection utilized multiple platforms: spaceborne (EO-1 Hyperion), airborne, and ground-based.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Data may reflect temporal bias inherent to the 2008-2015 collection period.
Provenance
Source
United States Geological Survey (USGS) and partnering volunteer agencies.
Collection Method
Compiled from Earth Observing-1 (EO-1) Hyperion hyperspectral data, using USDA Cropland Data Layer and SAGE crop calendars as reference.
