Objective:

The assessment of environmental risk and the evaluation of environmental policies requires information from diverse sources to be collected, organized, and combined. Evolutionary improvements in geographic information systems (GIS) now routinely allow the management and mapping of spatial-temporal information. However, there is a dearth of statistical methodology, not only to represent the complexities of the information but also to allow the uncertainty of the resulting inference to be quantified.

The development of statistical models to combine information of different types and spatial support is of vital importance. The primary objective of this research was to improve understanding of the biological integrity of stream and river systems in the United States Mid-Atlantic Region by combining information from separate monitoring surveys, available contextual information on hydrologic units, and remote sensing information.
