Abstract
Accurate digital land cover data is vital
to correctly estimating the impacts of nonpoint source
pollution on a watershed. However, producing
reasonable digital data characterizing current land
conditions in a watershed can be challenging due to
recent rapid growth in historically rural areas,
insufficient monetary and personnel resources, and
technical difficulties. This paper describes the
iterative process used to create digital existing and
future land cover data for use in the Forsyth County,
Hall County, and the City of Gainesville Community
Watershed Assessment. Significant efforts were made
to develop realistic, contiguous data that characterize a
combination of land cover and land use in a
geographic information system (GIS) format, using the
most recent data sources possible. These efforts
included integrating numerous different hard copy and
digital data sources to arrive at reasonable existing and
future land cover information that the project
stakeholders found acceptable for water quality
modeling purposes.
