This polygon shapefile represents Westover Field Airport noise level data in Amador County for 2010. This file was obtained 3/2/2016 by UCSB Library staff. It was originally available via http://www.co.amador.ca.us/departments/information-technology/gis/gis-data.
The following metadata was provided by the data creators: NoiseLevels2010 contains Community Noise Equivalent Level (CNEL) noise exposure contours (at 60 and 65 decibels, dB) representing anticipated airport operating conditions for 2010 at Westover Field Airport, Amador County. CNEL contours for the year 1989 are in the NoiseLevels1989 dataset. The contours were digitized by scanning the original hardcopy Figure 6.2 from the 1991 Westover Field Airport Master Plan (obtained from the Amador County Planning Department), georeferencing the resulting image to 2003 2-ft resolution County orthophotos and using it as a backdrop against which to hand-digitize the final vector layer (this dataset) in ESRI ArcEditor 9.2.
