What's New
Wrangell -
St. Elias National Park Land-Cover Mapping Project
|
 
GRS has been selected by National Park Service to perform
land-cover mapping of the 20-million acre Wrangell-St. Elias National Park. This park is the
largest national park within the national park system and is characterized by its rugged terrain, magnificent mountains and glaciers,
and diverse ecosystems. Five of the nine tallest mountains in North America are found in the park, as well as
some of the largest glacial features, such as the Hubbard Glacier, Malaspina Glacier (larger
than the state of Rhode Island), and the massive Bagley Ice Field
 
GRS is implementing our unique satellite image processing methodology
to develop the comprehensive and quantitative land-cover/vegetation map and associated database characteristics.
Field work and aerial surveys were accomplished to represent the 10-million acre southern portion of the park during the summer of 2004.
The northern portion of the park will be visited and sampled during the summer of 2005.
GRS develops very accurate image training data sets to represent the diverse landscape characteristics sampled during field efforts
in order to classify the eight mosaicked images that cover the park and develop the quanititative map database. All training data are
reviewed and verified to resolve any potential problems before using them during the classification process. GRS checks both pixel fidelity and confusion information to resolve potential classification problems.
The reulting map data set is quantitative in nature and can be used with virtually any land-cover classification system.
This data set be made available to resource managers, ecologists, biologists, and planners
and enable the users to develop and evaluate numerous alternative management scenarios and strategies.

Municipality of Anchorage
Fire Hazard Modeling
|
 
GRS was selected by the Municipality of
Anchorage (MOA) to perform a fire hazard and exposure modeling analysis.
GRS implemented our innovative satellite image processing techniques
to develop a comprehensive vegetation/land-cover map. GRS then evaluated the
quantitative land-cover information to estimate and map
these data as fire-fuels classes. Fuel class mapping was based on the quantitative land-cover characteristics and no cross-walking (jaywalking?) was performed. Fuels, topography,
weather, risk, and hazard information were integrated to develop a fire-exposure model within the
MOA urban-wildland interface. GRS also developed a mobile
fire mapping package that allows firefighters to map fire-incident
features in the field on a PDA using GPS and ArcPad mapping software.
The models and data are now available to planners and managers through
a decision support system that allows the users to evaluate incident scenarios
and mitigation strategies.

GRS awarded GSA contract.
|
GRS was recently awarded an Environmental
Services contract from the General Services Administration (GSA), the
purchasing arm of the federal government. This award allows federal agencies
to purchase Land Cover Mapping and Image Processing services from GRS
under the GSA schedule.
In making this award the GSA recognized
GRS's expertise as one of the premier image processing firms in the U.S.,
as well as the world. GRS has successfully mapped millions of acres while
completing projects in California, Oregon, Washington, British Columbia,
and Alaska.
