This annual digital ortho effort is implemented and administered by the Loudoun County Office of Mapping and Geographic Information. While primarily developed to capture annual base planimetric, environmental, and topographic updates throughout the County, the backdrop image can also serve as a reference layer for GIS analysis, Computer-aided Dispatching and E-911 services, Staff planning and development, historical record in land use/land cover change, and has the potential for use in many other public service projects. |

<DIV STYLE="text-align:Left;"><DIV><P><SPAN>Loudoun County annually obtains leaf-off, aerial imagery in the spring. In 2012, the imagery was captured with a DMC digital camera, in 4-band (R,G,B, and NIR) format. These files contain 1-foot ground-resolution, 8-bit, 4-band orthorectified aerial image map products in GeoTIFF version 6.0 file format. GeoTIFF files are uncompressed raster images complete with TFW coordinate information. The aerial imagery project encompasses the entire land area of the County of Loudoun, VA. Images were flown during leaf-off conditions and cover 5000' by 5000' and are tiled according to the 2002 VBMP 200-scale gridding schema (Virginia Geographic Information Network).</SPAN></P></DIV></DIV> |
