Title
Buildings 3D - [District of Columbia--Washington] {2013}
Description
This dataset contains 3D buildings for the District of Columbia in ESRI multipatch format. It includes structures originally captured from 2005 aerial imagery together with updates based on 2010 and 2013 aerial imagery. It was produced under contract to the District of Columbia by CyberCity3D, Inc. using stereo imagery and a proprietary extraction process that identifies roof polygon points and then creates entire structures from them by relating the roof polygons to an underlying Digital Elevation Model (2005 DEM developed by Earthdata) This dataset is an update to a previous 3D dataset produced in 2006 using 2005 imagery. It specifically includes updates to buildings identified in the course of the District of Columbia's separate planimetric update effort, which noted structures known that were added, modified between or deleted between 2008 and 2010. Although it was intended to capture all new buildings irrespective of whether or not they were identified through the planimetric update process, it is likely that building changes not identified through the planimetric update process may not have been captured. It also uses an updated production process that addresses base elevation errors in the earlier product, where some buildings appeared to be taller than they were because the earlier production process had left them floating above the desired surface and this had been corrected by extending the walls of those structures down to the desired surface. This dataset contains full buildings (including facades and detailed rooftops. There were also additional datasets delivered which broke out those elements into separate facades, complete roofs, and roof elements (protruding gabled windows, chimneys, elevator utility rooms, etc.). In many instances, row-houses and other contiguous buildings could not be broken apart using the process methodology and appear as a single structure. In some cases, entire blocks of row houses are represented as a single feature, though visually they can be distinguished easily. Many data gaps in the earlier dataset (largely due to missing or reduced-resolution source imagery) are corrected in this product. Based on comparison to DC's available planimetric datasets, there are still instances where particular structures are omitted or not updated in the current product, but we believe that upwards of 99% of the District's buildings are reflected in this dataset.
