This dataset depicts forest patches in Vermont. The dataset is reflective of summer 2016 conditions. The forest patch routine is based off of the 2016 high-resolution land cover tree canopy class. Three sizes of forest patches were delineated: small, medium, and large. In general, small patches consist of individual trees or small clumps containing 2-5 trees. Medium patches are generally comprised of 5-20 trees. Large patches contain 20 trees or greater and have a defined core area. The algorithm used to delineate the patches incorporated size, morphology, and perimeter/edge ratio criteria to define the patches. Size alone was not used as a criterion as narrowly configured groups of trees can connect over relatively large areas when viewed from above. One drawback of the processing approach was that the data had to be tiled to accommodate the billions of pixels in the source tree canopy dataset. As a result, artifacts, principally in the way of abrupt patch class changes exist along tile edges. Users should note that due to the size of the dataset basic display and geoprocessing operations can take a considerable amount of time. |
