Big Darby Creek Watershed Impervious Surfaces Theme

Data Description

Theme Name: Impervious Surfaces

Theme Description: represents estimation of imperviousness based on 1992 and 1997 landuse types and the associated degree of potential impact.

Data Origin: This dataset was derived from a complex overlay of the 1992 and 1997 Landsat Images for the Big Darby Creek Watershed (see 1992 and 1997 Landuse Themes on previous page). Original impervious estimates were done by Steve Gordon's watershed research team at OSU and were later translated into this coverage by FMSM Engineering.
