HWHYPCCMN1MM: Hyperspectral Reflectance Images of a Prairie Grassland at 1 mm Resolution

920 to 924 hyperspectral bands of reflectance data in the 400 to 1,000 nanometer spectral range. The data were collected by a Headwall Series E imaging spectrometer mounted 3 meters above ground at the Cedar Creek Ecosystem Science Reserve in Minnesota. Images were acquired during June/July 2014 and July 2015 for the biodiversity (BioDIV) experiment.

Use Cases

• Modeling the optical diversity-biodiversity relationship based on fine-scale spectral reflectance.
• Investigating spatial sensitivity of spectral signatures at local scales based on 1 mm resolution imagery.
• Calibrating or validating coarser-resolution remote sensing products using the high-resolution ground truth.
• Analyzing spectral changes in a prairie grassland ecosystem across two growing seasons.

Strengths

• Provides hyperspectral imagery at a 1 mm ground pixel size, described as among the finest spatial resolutions available.
• Covers a broad spectral range of 400 to 1,000 nanometers across 920 to 924 bands.
• Data is from a controlled, long-term ecological research (LTER) site, suggesting consistent collection methods.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• Temporal coverage is limited to two specific periods in 2014 and 2015.
