Ozark - St. Francis National Forests stand inventory data for vegetation, maintained in polygon format. Polygon boundaries that provide areas to be rotated for entry of timber inventory and management. Stand is defined as a spatially continuous group of trees and associated vegetation having similar structures and growing under similar soil and climatic conditions.<\/SPAN><\/P>

Data is typically intended for analysis and use at scales of 1:24,000 or smaller and in contextual conjunction with other thematic spatial and tabular data from other sources and sensors. These sources and sensors include: hydrography, elevation, aerial photos, satellite imagery, surface land ownership, etc. collected for use at comparable scales.<\/SPAN><\/SPAN><\/P>

Proclaimed forest boundaries were established by Congress. Within those boundaries, vegetation polygons will be delineated for all forest service administered lands and some private lands, because the private lands are intermingled with forest service land. Locations represent collections of these delineated polygons. Within each location, there will be no gaps; all land within each location falls within a delineated vegetation polygon. Note that vegetation polygons, as well as other features managed by FSVeg Spatial, are not meant to represent official or legal land boundaries. The features managed by FSVeg Spatial are meant to support vegetation management exercises; that is, data analysis of the landscape. To that extent, it is not important that the polygons represent exact ownership boundaries or exclude or include all private lands. Other feature classes can be brought in or overlaid to clip analysis areas to needed boundaries if necessary.<\/SPAN><\/SPAN><\/P>
