My research consists of developing new techniques for using remote sensing and other geospatial technologies within large-scale, multiobjective resource inventory systems. The scale of the Alaskan landscape, and the remoteness and lack of access to most of the forest and related ecosystems, requires development and application of inventory and monitoring techniques that largely depend on remotely acquired information, which must be integrated with field-based information in innovative and complex statistical sampling designs. I investigate how emerging geospatial/remote sensing technologies and analytical techniques can best be applied to assess the extent, condition, use, and trends associated with Alaska’s ecosystems and natural resources.
Why This Research is Important
This research is important because adequate technology has not been developed or applied to effectively, and comprehensively, inventory and monitor the forested ecosystems of Alaska. Therefore, critical baseline information on the extent, condition, trends, and uses of all Alaskan forests is not available to meet the needs for management and protection of these areas.
