Description: Davey Resource Group utilized LiDAR and aerial imagery to identify tree canopy cover and land cover classifications. Advanced image analysis methods were used to classify, or separate, the land cover layers from the overall imagery. The semi-automated extraction process was completed using Feature Analyst, an extension of ArcGIS®. Feature Analyst uses an object-oriented approach to cluster together objects with similar spectral (i.e., color) and spatial/contextual (e.g., texture, size, shape, pattern, and spatial association) characteristics.

Description: Arlington County Virginia real estate property polygons, also known as parcels. The features in this layer are the geometric representation of the parcel. The parcel boundaries are captured from source documents after they have been recorded. The data contains the RPC Master parcel ID for each parcel. In the case of condominiums there is a single polygon that references a master parcel ID. That master parcel ID then references 1 to many condo parcel IDs.Contact: Department of Environmental ServicesData Accessibility: Publicly AvailableUpdate Frequency: WeeklyLast Revision Date: 10/19/2023Creation Date: 10/19/2023Feature Dataset Name: REALayer Name: REA_Property_poly
