The aerial photography and creation of the subsequent building data was executed to capture the existing ground conditions at a specific point in time for the purpose of GIS analysis. A GIS is a system of computer software, hardware, and data that allows a user to manipulate, analyze, and present information that is tied to a spatial location. GIS technology is used in scientific investigations, resource management, development planning, and many other applications that require analysis of spatial data. VGIN sub-contracted with the Sanborn Map Company to execute a Statewide mapping contract in the years 2009 to 2012. This contract updated and enhanced the existing 2006 and 2007 map data. The Virginia Geographic Information Network (VGIN) is the lead public agency in the Commonwealth for spatial data and GIS. VGIN's mission is to facilitate the cost-effective development and use of spatial data, GIS, and related technologies in organizations throughout the Commonwealth. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Building polygons for Radford, Virginia. For 1"=200' or (1:2400) scale source mapping (1' GSD imagery): all structures with roofs having an aerial coverage of 200 square feet or greater will be captured from the photography as a polygon. Buildings are delineated by tracing the base of the structure for dwellings, businesses, houses, barns. For 1"=100' or (1:1200) source scale mapping (6" GSD imagery): all structures with roofs having an aerial coverage of 100 square feet or greater are captured from the photography as a polygon. Buildings are delineated by tracing the base of the structure for dwellings, businesses, houses, house trailers, garages, barns, and accessory structures.</SPAN></P></DIV></DIV></DIV> |
