Abstract
Spatial Analysis and Decision Assistance (SADA) is a Windows freeware program that
incorporates spatial assessment tools for effective environmental remediation. The software
integrates modules for GIS, visualization, geospatial analysis, statistical analysis, human health and
ecological risk assessment, cost/benefit analysis, sampling design, and decision support. SADA began
as a simple tool for integrating risk assessment with spatial modeling tools. It has since evolved into a
freeware product primarily targeted for spatial site investigation and soil remediation design, though
its applications have extended into many diverse environmental disciplines that emphasize the spatial
distribution of data. Because of the variety of algorithms incorporated, the user interface is engineered
in a consistent and scalable manner to expose additional functionality without a burdensome increase
in complexity. The scalable environment permits it to be used for both application and research goals,
especially investigating spatial aspects important for estimating environmental exposures and
designing efficient remedial designs. The result is a mature infrastructure with considerable
environmental decision support capabilities. We provide an overview of SADA's central functions and
discuss how the problem of integrating diverse models in a tractable manner was addressed.
