  skos:definition """State and local government officials have long struggled with the
complexity involved in protecting and improving water quality in their
jurisdictions. Due to technical, environmental, and regulatory
complications, these officials have grappled with this important
issue, often coming up short of a workable, consistent plan for water
resource management. Recently, scientific literature has shown that
the amount of impervious surface in a watershed proves to be a useful,
easily identifiable indicator of overall water quality. In response to
this finding, the Towson University Center for Geographic Information
Sciences (CGIS) and its partners--the Towson University Department of
Geography and Environmental Planning, the Maryland Space Grant
Consortium, the Washington College Center for the Environment and
Society, and the Maryland Virtual High School--completeda project to
map impervious cover for the entire Chesapeake Bay and Maryland
Coastal Bays watersheds. The goal of this project is to supply state
and local official with the impervious surface data and with the
technical and theoretical background they need to integrate
imperviousness into their water quality protection measures.

To complete the impervious surface mapping project, CGIS used remote
sensing and geographic information system (GIS) technologies to
identify pervious and impervious land cover types throughout the
Chesapeake Bay and Maryland Coastal Bays watersheds. The data was then
"clipped" by watershed and county boundaries tomake the information as
useful as possible to its intended audience--state and local
government officials. This data was then uploaded onto a CGIS server
to be distributed to its end users via an online Infomart, complete
with raw remotely sensed data (Landsat 7 EMT+), geospatial data, and
background information onremote sensing/digital image
processing. Additionally, the Infomart contains a link for K-12
teachers, which includes lesson plans on imperviousness that teachers
can use within their classrooms. K-12 teachers and their students have
already played an integral role in the impervious surface project by
ground truthing over 15,000 land-cover points, using portable GPS
units supplied to them by CGIS. Finally, the Infomart serves as the
focus of a Project NEMO (Non-Point Education of Municipal Officials),
university-based outreach program to educategovernment officials on
watershed ecology, imperviousness, and potential mitigation measures.
