Registration Map of the Forest Ecosystem Dynamics Project Spatial Data Archive

The nature and extent of the impacts of these changes, as well as the feedbacks to global climate, may be addressed through modeling the interactions of the vegetation, soil, and energy components of the boreal ecosystem. The Howland Forest research site lies within the Northern Experimental Forest of International Paper. The natural stands in this boreal-northern hardwood transitional forest consist of spruce-hemlock-fir, aspen-birch, and hemlock-hardwood mixtures.

The topography of the region varies from flat to gently rolling, with a maximum elevation change of less than 68 m within 10 km. Due to the region's glacial history, soil drainage classes within a small area may vary widely, from well drained to poorly drained. Consequently, an elaborate patchwork of forest communities has developed, supporting exceptional local species diversity.

The Registration Map is the combination of several data layers and was used to perform geometric and georeferencing corrections to the imagery acquired for the Forest Ecosystem Dynamics study area. The map contains two sets of Global Positioning System (GPS) points for differing dates, the study area roads from both the United States Geological Survey and the International Paper Company, and streams and open water bodies from the International Paper Company.
