1. Impervious Surface Mapping with High Resolution Satellite Imagery
There
is a growing demand for environmentally friendly storm water management
practices. Relatively recent federal mandates, outlined in the Clean
Water Act (1999) and enforced through the EPA’s National Pollutant
Discharge Elimination System (NPDES), compel states to adopt comprehensive
municipal storm water management rules by 2003! Because impervious
surface maps are an essential input layer to all storm water analysis
models, methods for accurately mapping and measuring the extent and
quantity of impervious surfaces are of critical importance.
Beginning in
the spring of 2003, researchers at the Center for Advanced Spatial
Technologies (CAST) were investigating the feasibility of using DigitalGlobe
Quickbird for the mapping of urban surfaces. Funding from a U.S.G.S./AmericaView
grant supported this research, and the imagery used in the investigation
was a donation to AmericaView states from DigitalGlobe, Inc.

2. Riparian Corridor Delineation
The
purpose of this study was to identify land-use and land-cover types
existing along stream channels within the City of Fayetteville, Arkansas’
utility planning area for the expressed purpose of identifying riparian
corridor. Riparian habitat comprises the zone adjacent to aquatic
systems with flowing water that contains elements of both aquatic
and terrestrial ecosystems that mutually influence each other. Therefore,
a riparian corridor is area composed of continuous riparian habitat,
like the land on either side of a river bank or the area around a
lake. Protecting riparian corridors improves water quality, provides
wildlife habitat and prevents flood damage, and is, therefore, a critical
part of any watershed management plan.
