GIS & Spatial Analysis

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, FHAAST 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:

  • Digital Mobile Sketch Mapping (DMSM)
  • Insect and Disease Detection Survey Maps

Data and 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:

  • Digital Mobile Sketch Mapping System (DMSM)
  • Risk Modelling Application (RMAP)
  • Forest Health Advisory System

Risk and Hazard Mapping

The GIS and Spatial Analysis program at FHAAST 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.

  • National Insect and Disease Risk Map Viewer
  • National Forest Damage Agent Range Maps
  • Southern Pine Beetle County Hazard Rating Maps
