Clean Air Mapping and Analysis Program

Project Description
Clean Air Mapping ana Analysis Program(C-MAP) is an assessment
tool developed by the Clean Air Markets Division (CAMD) to
better understand and characterize the effectiveness of
environmental programs such as the Acid Rain Program. The
primary goal behind the development of a GIS was to gain a
thorough understanding of the impacts of sulfur dioxide and
nitrogen oxides emission reductions to the environment. The
decision to implement a GIS stemmed from a need to better
understand the implications of answers to policy questions
regarding acid rain control, and therefore to improve the
decision-making process. The extensive GIS database, available
for download, enables users to visually integrate various
emissions and effects data in map format, using their own GIS
software. Sample maps illustrating current trends and policy
issues of interest are displayed in the map gallery for viewing
and download.

GIS is helping in the assessment of whether current control
levels provide adequate protection of human health and the
environment. CAMD is using GIS to explore spatial patterns and
analyze regional trends in air quality, visibility, surface
water quality, acid deposition and forest health, as related to
emission levels:

1. Display and compare trends in environmental indicators (for
example, acid deposition, surface water chemistry, ambient air
concentrations) at national or regional scales.

2. Display such trends in environmental indicators overlaid with
trends in emissions.

3. Display trends at different annual time scales (for example
over 1-, 5-, or 10-year periods), or design annual vs. seasonal
comparisons.

4. Mark progress toward environmental goals
