The GIS and Spatial Analysis program's core mission is to support Forest Health Protection (FHP) field units and the Washington Office in the use and application of geographic information systems (GIS) and other spatial analysis technologies for the purpose of collecting, analyzing, and disseminating spatial information related to the health of the nation's forests. The program supports and maintains national spatial databases for annual insect and disease aerial detection surveys and risk maps related to forest health all of which provide data for upward reporting of forest health conditions to our cooperators and stakeholders. FHTET maintains a GIS laboratory that provides training and technical assistance to field personnel, develops new technology and applications for the collection and dissemination of spatial data, and produces spatial data products.

The GIS and Spatial Analysis program provides leadership in the development and implementation of spatial data standards for Forest Health Protection. This is accomplished by working with FHP Regions/Area and Field Office personnel to ensure that forest health data is compatible with national standards and is available for upward reporting to regional and national levels. In addition, FHTET acts as the Deputy Area Data Administrator for State and Private Forestry.

GIS services are provided by the GIS and Spatial Analysis program to personnel such as entomologists, pathologists, and aerial surveyors. Personnel accessing these services reside in the USDA Forest Service, other Federal agencies, and the State and private sector. Services are generally provided on a time-available, cost-reimbursable basis to units outside the Forest Service.
Detection Surveys - Insect and Disease Survey (IDS) Database

Data collected during aerial and ground detection surveys is standardized and assembled into a national IDS database housed at FHTET. The GIS and Spatial Analysis Program also develops mobile technology such as the Digital Mobile Sketch Mapping (DMSM) system which supports both ground and aerial detection work. More information about DMSM and access to the IDS database and products:

Data Development

In addition to maintaining a national IDS spatial database, the GIS and Spatial Analysis program frequently develops or sponsors the construction of datasets that aid FHP Regions and Field Office personnel in conducting assessments of forest health.  Examples of these data include the production of GIS layers depicting forest attributes, such as basal area (BA) (done in collaboration with FHTET’s Remote Sensing and Image Analysis program), and the development of a soil drainage and productivity index for determining the relative amount of water and nutrients available to plants.

Risk Mapping

The GIS and Spatial Analysis program at FHTET provides support for both tactical and strategic forest health risk assessments. In addition, this program coordinates, in collaboration with the USDA Forest Service Forest Health Monitoring program (FHM), the development of a National Insect and Disease Risk Map (NIDRM) and database.

The primary goal of NIDRM is to provide Congress, USDA officials, and federal and state land managers with a periodic strategic assessment of risk of tree mortality due to major insects and diseases. NIDRM is more than “just a map”, it represents a compendium of about 190 individual risk models, all constructed within a common GIS-based multi-criteria framework that can account for regional variations in forest health concerns.

The multi-criteria framework, used by FHTET for the development of NIDRM and other risk assessments, provides a consistent, repeatable, transparent process.  This process enables interactive spatial and temporal risk assessments to be conducted at various levels to aid in decision making thus enhancing the utilization and maintenance of forest health risk maps within and outside the National Forest System.

Information about NIDRM and other risk mapping efforts may be obtained here:

Application Development

With the growing need to conduct complex spatial analysis and manage large datasets, the GIS and Spatial Analysis program has begun to develop applications to aid in data management and analysis. Examples of applications developed by FHTET include:
