Our research in this area has concentrated on the following: (1) developing individual tree and forest growth models that incorporate stand structure, weather, and anthropogenic factors, and use of these models in impact analyses and as decision support tools; (2) incorporating auxiliary information into forest, water, and land use measurement and estimation methods; (3) developing methods for using remote sensing and satellite-based digital data in sampling and resource survey methods; (4) improving geographic information systems capabilities for ecological and economic spatial analysis of resources; and (5) synthesis of the above in terms of web-based information systems for resource analyses and decision making.
