Our Nation's forests provide a wealth of ecological, social, and economic resources. These forest lands cover over 300 million hectares of the United States, or about one third of the total land area. Accurate and timely information about them is essential to their wise management and use. The mission of the Forest Service's Forest Inventory and Analysis (FIA) program is to "improve the understanding and management of our Nation's forests." Remote sensing-based maps and geospatial datasets are playing an increasing role in improving that understanding. Examples of maps portraying forest composition and spatial distribution, seen on the cover of this issue and described within in an article by Ruefenacht and others, were produced by a collaboration of three USDA Forest Service entities: the Remote Sensing Applications Center (RSAC), Forest Health Monitoring, and FIA. In this article, the FIA program is introduced and FIA's remote sensing and geospatial activities are highlighted.
