A Green Infrastructure map for Campbell County in central Virginia was developed to support land cover and land use modeling. Digital aerial imagery at 3 foot resolution was classified to a Green Infrastructure Level 1 classification scheme with the following classes: 1) Non Woody Vegetation, 2) Woody Vegetation, 3) Impervious, 4) Water and 5) Bare Soil. The image was classified using Classification and Regression Tree techniques (CART analysis) and raster modeling. The classification accuracy assessment gave an overall accuracy of 95.6% for the Level 1 classification.This feature class was developed in the Virginia State Plane HARN coordinate system, but redefined as NAD83 to align with the 2011 Virginia Geographic Information Network (VGIN) imagery. |
