ForWarn Online Tool For Forest Disturbances Monitoring

USDA Forest Service and NASA Release Web-Based Tool that Helps Natural Resource Managers Respond to Forest Disturbances.

The USDA Forest Service's Eastern Forest and Western Wildland Environmental Threat Assessment Centers recently unveiled a product that helps natural resource managers rapidly detect, identify, and respond to unexpected changes in the nation's forests by using web-based tools. ForWarn, a satellite-based monitoring and assessment tool, recognizes and tracks potential forest disturbances caused by insects, diseases, wildfires, extreme weather, or other natural or human-caused events. The tool complements and focuses efforts of existing forest monitoring programs and potentially results in time and cost savings.

The prototype version of ForWarn has successfully operated since January 2010 and uses NASA MODIS (Moderate Resolution Imaging Spectroradiometer) satellite imagery to recognize and track changes in vegetation across the nation, providing a near-real-time view of potential forest disturbance and recovery. ForWarn uses a web-based map tool, the Forest Change Assessment Viewer, to provide an eight-day, coast-to-coast snapshot of the U.S. landscape, interpret images, and create geographically relevant maps. The viewer allows users to explore and share recent and archived forest disturbance maps.

"ForWarn epitomizes the type of product envisioned when the Threat Assessment Centers were created," says Danny C. Lee, Director of the Eastern Threat Center. "This tool literally puts space-age technology into the hands of forest resource professionals. It's a remarkable collaborative achievement." The Eastern and Western Threat Centers are jointly supported by the Forest Service's National Forest System, State and Private Forestry, and Research and Development.

The Eastern and Western Threat Centers, NASA Stennis Space Center's Applied Science & Technology Project Office, and other federal and university partners developed ForWarn in response to the Healthy Forests Restoration Act of 2003. The Act specifies development of a comprehensive National Early Warning System to detect potential catastrophic environmental threats to forests. ForWarn is a strategic research component of the National Early Warning System and is currently being tested by federal and state forest and natural resource managers throughout the country.

"We are excited to unveil ForWarn and the Forest Change Assessment Viewer, intuitive products that use advanced technology to provide a current look at forest changes and help focus on-the-ground response efforts," says William Hargrove, Eastern Threat Center lead ForWarn researcher. "Our goal is to help natural resource managers, scientists, and other decision makers better identify, understand, and react to environmental disturbances. We will continue to refine and update these tools that will help guide activities and resources in impacted areas."

Joe Spruce, lead scientist on this project at NASA Stennis, says that ForWarn provides "the USDA Forest Service and its partners with vital broad-scale information on the location and extent of regionally evident forest disturbances, helping resource managers conduct more detailed aerial and field surveys." He continues, "This effort is precisely the Applied Sciences Program's mission – to move NASA science to operational users for real socio-economic benefit."

The Eastern and Western Threat Centers are currently offering webinars on ForWarn and additional decision support tools. Sessions provide a ForWarn overview, highlight a variety of forest disturbances detected during the 2010 and 2011 growing seasons, and feature Eastern and Western Threat Center scientists demonstrating the tool's ability to retrospectively examine forest disturbances detected during the prior two years. Contact Bill Christie, Eastern Threat Center GIS specialist, (828) 257-4370 or by email at wchristie@fs.fed.us for webinar and online tutorial information.

ForWarn is the result of ongoing cooperation among federal and university partners. In addition to the Forest Service and NASA, the partnership includes the US Geological Survey; the Department of Energy's Oak Ridge National Laboratory; and the University of North Carolina Asheville's National Environmental Modeling and Analysis Center.

USDA web-based Soil Survey

Via. The latest version of the Web Soil Survey 2.1 (WSS) was recently launched by the USDA’s Natural Resources Conservation (NRCS). The web-based program provides anyone with computer access a wealth of soils information including soil maps, properties, and interpretations aimed at helping its visitors with land use decisions. The web site, originally launched in August 2005, continues to be improved and enhanced to meet the demands of its growing customer base of several million hits a year.

The first and most noticed change is the addition of a “Search” feature. This feature allows the user to type in a keyword or phrase, and WSS will return a list of links to the places within the application that provide information containing the keyword or phrase.

Another major addition provides the user the capability to download the raw soil data clipped to the geographic extent of the defined area of interest (AOI). This data can then be used in the user’s local geographic information system (GIS).

In addition, the ability to print soil and interpretive maps on multiple pages has been added. Based on the size and shape of the AOI and the map scale chosen by the user, the WSS application offers the user a choice of page layout configurations and page sizes.

A distance measuring tool has been added. This tool provides the length of individual line segments that the user draws on the map as well as the cumulative length of multiple segments.

On the Soil Map tab the customer can access a pop-up map unit description. In WSS 2.1 the user can now print these individual descriptions. Another enhancement provides more accurate and up-to-date navigational data layers such as streams, roads, and political boundaries to WSS. The availability of high resolution, color background imagery has been expanded.

There has also been additional server space added to the system. This will allow more concurrent users to access the Web Soil Survey, and should improve the performance of the application to individual users.

These are only a sampling of the enhancements included in the latest version of WSS. A large number of minor enhancements have also been added. More enhancements are planned for future releases.

Since its beginning, the Web Soil Survey has attracted a wide array of online visitors from all over the world. During the first few months of its existence, the site averaged about 1000 users per day, but now the site has seen that number increase dramatically to about 4000 per day.

Soil surveys provide critical information for land use decisions, both on the farm and in the city. Whether a developer is looking to build on or purchase land, or a farmer is considering alternative crops, soil survey data is a critical element in the equation that produces profits. This is essential to rural America and the need for producers and ranchers to maximize productivity without harming natural resources.

Making soils information available on the web has been a major achievement for NRCS and with the agency’s ongoing commitment to make the process better and easier for the customer, the important information can find its way into the hands of those making natural resource decisions. NRCS is a science-based USDA federal agency committed to the preservation of the nation’s natural resources through the use of conservation.

Making GIS data easy to share

The Agriculture Department is seeking information about methods for delivering, disseminating and integrating large geospatial datasets for its Farm Service Agency and other users. USDA is interested in commercial software and/or online mapping interface services that could replace FSA's current systems.

Those systems are outdated, allow only limited access and make it difficult to share information, USDA said in the request for information posted on the Federal Business Opportunities Web site Jan. 25.

USDA wants an environment that consists of a centralized, fully integrated architecture. It could potentially be hosted at its National IT Center in Kansas City, Mo., and Aerial Photography Field Office in Salt Lake City. Centralizing the hosting of geospatial applications would improve communication between FSA headquarters, state offices and service centers.

By allowing users to access data from a central location, the system would reduce the need to request information from specific service centers.

FSA administers programs such as crop commodity price support, disaster relief and assistance for conservation practices in part by digitizing and maintaining agricultural field boundaries or common land units from digital ortho-imagery supplied by the National Agriculture Imagery Program. The agency also verifies that farmers’ and ranchers’ agricultural practices follow USDA guidelines.

The aerial imagery is viewed at 2,350 county service centers, which store and manage the geospatial data for their locales. The centers also use the imagery to help identify farm parcels and acreages. In addition, the centers store and use supplemental data provided by state and local governments and private-sector sources.

Each center has state information technology employees who maintain, update and secure the infrastructure. Clients above the service-center level can't access information because users can only work with data on the local server and within their administrative area. However, cataloging and publishing metadata on centers’ data holdings would further tax the already overstretched staff resources at the state and local levels.

Furthermore, the service centers rely on infrastructure hardware that is targeted for replacement, and an increasing number of business applications are migrating to a centralized, online environment.

The Office of the Chief Financial Officer also wants the agency to consider moving the major geospatial hardware from county service centers and consolidating the equipment at six data centers, which would reduce the risks to physical and information security.

Responses to the RFI are due Feb. 29.
