Protecting Urban History

Maximizing the data collected from airborne lidar helps protect historic structures in older cities In Part I last month, we outlined the research performed in Dublin, Ireland, and Brooklyn, N.Y., using hyperspectral scanning to help old cities protect historically significant buildings during new construction projects. In Part II, NYU professor, Dr. Debra Laefer, explains how...

Protecting Urban History

Researchers demonstrate how lidar, combined with imagery and hyperspectral data, helps prevent costly damage to historic buildings in urban construction zones. With every new underground urban rail or roadway tunnel, deep foundation shaft for a new building, or even simple streetscape upgrade, historically significant archi­tecture in older city centers can become vulnerable. Earth displacement from...

Different visualizations of the same VNIR+SWIR hyperspectral image (of Wizard Island, Crater Lake, OR) draped over a lidar bare-earth digital elevation model. The variation in vegetation, snow, soil/geologic cover, and even water properties can be highlighted with different combinations of spectral wavelength images.

HSI on the Fly

One company details mapping applications of airborne hyperspectral imagery for agriculture, forestry, and resource mapping. By Patrick Burns and Scott Nowicki, PhD Remote sensing imagery has been collected with many different camera systems for many different applications over the past 50 years of the industry.  Visible remote sensing imagery provides interpretable information available to most...
