Current PE&RS Cover

PE&RS August 2009

NCDC Imaging contracted with Terra Remote Sensing Inc (TRSI) for the acquisition of 1-meter resolution narrowband (5 nm) hyperspectral imagery and accompanying lidar over Milwaukee, Wisconsin (95 square miles). Refl ectance spectra of representative tree species were collected in the field using a FieldSpec® 3 spectroradiometer system from ASD, Inc.

NCDC analysts used a LiDAR-derived digital surface model and a 4-band multispectral image that was derived from the hyperspectral imagery to create an accurate tree canopy polygon dataset. The canopy spectral signatures collected with the ASD FieldSpec 3 spectroradiometer were then utilized in conjunction with the hyperspectral imagery to classify Ash trees over the study area. The hyperspectral imagery was evaluated for detection of imperceptible stress in ash species as a tool for rapid early detection for emerald ash borer. The red points shown on the cover image are the tree points for all trees in the given area. The green polygons display the tree canopy in the same area and lastly the yellow points represent the Ash trees.

The cover image and corresponding highlight article are sponsored by ASD Inc. of Boulder, Colorado, manufacturer of the rugged and truly portable FieldSpec 3 line of spectroradiometers (www.asdi.com).
