Multiscale Topology of the Spectroscopic Mixing Space: Impervious Substrates
Christopher Small, Daniel Sousa
Characterization of topology and dimensionality of spectral feature spaces provides insight into information content. The objective of this study is to characterize topology and sp…
Topological Generality and Spectral Dimensionality in the Earth Mineral Dust Source Investigation (EMIT) using Joint Characterization and the Spectral Mixture Residual
Daniel Sousa, Christopher Small
NASA's Earth Surface Mineral Dust Source Investigation (EMIT) mission seeks to use spaceborne imaging spectroscopy (hyperspectral imaging) to map the mineralogy of arid dust source…
Linking Common Multispectral Vegetation Indices to Hyperspectral Mixture Models: Results from 5 nm, 3 m Airborne Imaging Spectroscopy in a Diverse Agricultural Landscape
Daniel Sousa, Christopher Small
For decades, agronomists have used remote sensing to monitor key crop parameters like biomass, fractional cover, and plant health. Vegetation indices (VIs) are popular for this pur…
Joint Characterization of the Cryospheric Spectral Feature Space
Christopher Small, Daniel Sousa
Hyperspectral feature spaces are useful for many remote sensing applications ranging from spectral mixture modeling to discrete thematic classification. In such cases, characteriza…
Global cross-calibration of Landsat spectral mixture models
Daniel Sousa, Christopher Small
Data continuity for the Landsat program relies on accurate cross-calibration among sensors. The Landsat 8 OLI has been shown to exhibit superior performance to the sensors on Lands…
Observations of cyclone-induced storm surge in coastal Bangladesh
Soyee Chiu, Christopher Small
Water level measurements from 15 tide gauges in the coastal zone of Bangladesh are analyzed in conjunction with cyclone tracks and wind speed data for 54 cyclones between 1977 and…
