Description: This is an impervious classification of Connecticut. The thematic information includes three classes in a single feature class: 1 - Building, 2 - Road and 3 - Other. It was based on color infrared aerial imagery with a 1' spatial resolution that was collected between March 18th and 30th, 2012. Impervious features from existing planimetric data sets were updated based on the 2012 imagery through photo interpretation and heads up digitizing through ArcScan. All features greater than 800 square feet in size were included in the data set. The use of ArcScan and the use of the existing planimetric data sets are discussed in the "Lineage/Process Step" section of this metadata report. Upon completion of the entire State of Connecticut the raster images were then vectorized and are supplied at the town level for distribution. The state of Connecticut was collected with the US Census Bureau state boundary, and the town's were clipped using the DEEP TOWN_CLIP.shp. Each town is represented as 1) an .img file and 2) a vectorized feature class within a geodatabase, both consisting of an extent of all of the imagery tiles that contained the town within a 300' buffer, and 3) a vectorized feature class within a geodatabase consisting of the town clipped to the DEEP TOWN_CLIP.shp.Clipped to the Town of Enfield
