Effects of DEM source and resolution on WEPP hydrologic and erosion simulation: A case study of two forest watersheds in northern Idaho

Publications Posted on: December 02, 2009
The recent modification of the Water Erosion Prediction Project (WEPP) model has improved its applicability to hydrology and erosion modeling in forest watersheds. To generate reliable topographic and hydrologic inputs for the WEPP model, carefully selecting digital elevation models (DEMs) with appropriate resolution and accuracy is essential because topography is a major factor controlling water erosion.

Mapping upland hardwood site quality and productivity with GIS and FIA in the Blue Ridge of North Carolina

Publications Posted on: July 20, 2009
The forested ecosystems of the southern Appalachians are some of the most diverse in North America due to the variability in climate, soils, and geologic parent material coupled with the complex topography found throughout the region. These same characteristics cause stands of upland hardwoods to be extremely variable with regard to site quality and productivity.

Development of input data layers for the FARSITE fire growth model for the Selway-Bitterroot Wilderness Complex, USA

Publications Posted on: February 13, 2009
Fuel and vegetation spatial data layers required by the spatially explicit fire growth model FARSITE were developed for all lands in and around the Selway-Bitterroot Wilderness Area in Idaho and Montana. Satellite imagery and terrain modeling were used to create the three base vegetation spatial data layers of potential vegetation, cover type, and structural stage.

Guidebook on LANDFIRE fuels data acquisition, critique, modification, maintenance, and model calibration

Publications Posted on: February 05, 2009
With the advent of LANDFIRE fuels layers, an increasing number of specialists are using the data in a variety of fire modeling systems. However, a comprehensive guide on acquiring, critiquing, and editing (ACE) geospatial fuels data does not exist. This paper provides guidance on ACE as well as on assembling a geospatial fuels team, model calibration, and maintaining geospatial data and documentation.

Forests on the Edge: A GIS-based Approach to Projecting Housing Development on Private Forests

Publications Posted on: March 08, 2007
The private working land base of America’s forests, farms, and ranches is being converted at the rate of nearly 1,620 ha (4,000 acres) per day with tremendous economic, ecological, and social impacts.

Fuels Products of the LANDFIRE Project

Publications Posted on: February 02, 2007
The LANDFIRE project is a collaborative interagency effort designed to provide seamless, nationally consistent, locally relevant geographic information systems (GIS) data layers depicting wildland fuels, vegetation and fire regime characteristics. The LANDFIRE project is the first of its kind and offers new opportunity for fire management and research activities.

An Overview of FlamMap Fire Modeling Capabilities

Publications Posted on: February 02, 2007
Computerized and manual systems for modeling wildland fire behavior have long been available (Rothermel 1983, Andrews 1986). These systems focus on one-dimensional behaviors and assume the fire geometry is a spreading line-fire (in contrast with point or area-source fires).

Chapter 14 - Dissemination of LANDFIRE Prototype Project data

Publications Posted on: October 11, 2006
The transfer of LANDFIRE data to users is the most important aspect of the Landscape Fire and Resource Management Planning Tools Project (LANDFIRE Prototype Project). The creation of an accurate, consistent, nationwide data set provides the foundation for a successful project. The final step is to make the data readily available to the user community. User capabilities and needs vary widely.

Chapter 13 - Perspectives on LANDFIRE Prototype Project Accuracy Assessment

Publications Posted on: October 11, 2006
The purpose of this chapter is to provide a general overview of the many aspects of accuracy assessment pertinent to the Landscape Fire and Resource Management Planning Tools Prototype Project (LANDFIRE Prototype Project). The LANDFIRE Prototype formed a large and complex research and development project with many broad-scale data sets and products developed throughout its various stages.

Chapter 12 - Mapping wildland fuel across large regions for the LANDFIRE Prototype Project

Publications Posted on: October 11, 2006
The Landscape Fire and Resource Management Planning Tools Prototype Project, or LANDFIRE Prototype Project, required that the entire array of wildland fuel characteristics be mapped to provide fire and landscape managers with consistent baseline geo-spatial information to plan projects for hazardous fuel mitigation and to improve public and firefighter safety. Fuel maps were some of the core deliverables of the LANDFIRE Prototype Project.
