GNN Forest Structure for the Pacific Northwest - Map Service
Dataset Identification:
Resource Abstract:
This web mapping service displays the Vegetation Class attribute of the Pacific Northwest GNN Forest Structure Model. Many
other attributes are available in the data set. For more information about these other attributes, and to download the data,
please visit the LEMMA site here: <div> <br /> </div> <div> <a href="http://lemma.forestry.oregonstate.edu/data/structure-maps">http://lemma.forestry.oregonstate.edu/data/structure-maps</a>
<br /> </div> <div> <br /> </div> <div> GNN models for individual species are also available at <a href="http://lemma.forestry.oregonstate.edu/data/species-maps">http://lemma.forestry.oregonstate.edu/data/species-maps</a>.
The GNN models apply only to forest land (areas currently or with the potential to support at least
10% tree cover), because a consistent regional plot sample of non-forest areas is unavailable. Most users will want to use
"masked" versions of the GNN maps, which are provided by the LEMMA site, where areas of non-forest land cover developed
from the GAP Analysis Program's Ecological Systems map have been embedded in the GNN grids. <br /> </div> <div> <br /> </div>
<div> <div> The most current GNN data are Landsat-based maps of forest structure and composition for
Washington, Oregon, and northwestern California. The maps were developed primarily for two research projects: Northwest Forest
Plan (NWFP) Effectiveness Monitoring ( <a href="http://lemma.forestry.oregonstate.edu/projects/nwfp">http://lemma.forestry.oregonstate.edu/projects/nwfp</a>),
and Carbon Monitoring for Wooded Ecosystems (CMONster) <a href="http://lemma.forestry.oregonstate.edu/projects/cmonster">http://lemma.forestry.oregonstate.edu/projects/</a>
</div> <div> <a href="http://lemma.forestry.oregonstate.edu/projects/cmonster">cmonster</a>). <br /> <br />Funding was provided
by the USDA Forest Service (Pacific Northwest Region and Pacific Northwest Research Station, Resource Monitoring
and Assessment Program), Oregon Department of Forestry, Washington Department of Natural Resources, and NASA. </div> <div>
