Environmental Benefits Mapping and Analysis Program (BenMAP)
Downloads
BenMAP is a PC-based GIS program that estimates the health benefits associated with air quality changes by creating population-level exposure surfaces, estimating changes in incidences of a wide range of health outcomes associated with ambient air pollution, and then placing an economic value on these reduced incidences. BenMAP produces both point estimates and distributions of incidence and value estimates. The model is currently available in three versions.

- BenMAP 4.0 (September 2010): This is the current version of the BenMAP software and we encourage existing users to upgrade to this new version. BenMAP 4.0 incorporates a number of key improvements, including the use of a new database that greatly improves compatibility with Microsoft Vista and Windows 7 operating systems; this new database is also able to store and access a much larger amount of data. Version 4.0 includes updated mortality rate projections based on newer data as well as more spatially resolved morbidity rates for many areas of the country. Note that all configuration and aggregation, pooling and valuation files constructed using previous versions of BenMAP should be compatible with version 3.0.

- BenMAP Command Line
This scripting tool is useful to analysts who would like to execute a large number of BenMAP runs in succession. Users can define separate scripts for each stage of a BenMAP analysis, including: the creation of air quality grids, the running of the configuration stage, the running of the aggregation, pooling and valuation stage and exporting of results. Included in the download are example scripts. This program must be run through the MS-DOS command prompt.- BenMAP Command Line (zip file) (54 MB)
- PopGrid
BenMAP contains U.S. population data matched to a variety of commonly used air quality grids. However, users wishing to run an analysis based on an air quality grid not already defined in BenMAP may need to import a new population file matched to that grid definition. The PopGrid program (zip file) (552 MB) allocates the 2000 block-level U.S. Census population to a user-defined grid, creating a population file ready for importation to BenMAP.
- Configuration Files
Users can save their health impact analysis options within BenMAP configuration (.cfg) and aggregation, pooling and valuation (.apv) files. Below we provide files that specify the current U.S. EPA-default options for PM, ozone, NO2 and SO2 health impact assessments.- PM

- BenMAP 1.0: The legacy version of BenMAP that was used in developing the regulatory benefits analyses for the Nonroad Diesel and Clean Air Interstate rules. This version of the model is designed for regional and national-scale analyses within the Continental United States, and uses a fixed set of population data and air quality model grid definitions. Download time for this version is significant due to the large databases which support the analyses.
