2004 Ortho Tile Index

This 2006 Orthoimagery Tile Index file can be used to geo-reference the individual image tiles across the City. This tile index is used in conjunction with the 2006 Orthoimagery by individual Borough download. Full metadata on the Aerial & Orthoimagery can be found at: https://github.com/CityOfNewYork/nyc-geo-metadata/blob/master/Metadata/Metadata_AerialImagery.md

The true color orthoimages were acquired as part of the DC Geographic Information System (DC GIS) and captured at 15cm pixel resolution. A companion downloadable mosaic is available as a compressed MrSID format. The final orthophotography deliverable products for this project consist of 328 ortho tiles at a scale of 1 to 2400.

The true color orthoimages were acquired as part of the DC Geographic Information System (DC GIS) and captured at 20cm resolution. A companion downloadable mosaic is available as a compressed MrSID format.

The true color orthoimages were acquired as part of the DC Geographic Information System (DC GIS) and captured at 1 foot resolution. A companion downloadable mosaic is available as a compressed MrSID format.

The true color orthoimages were acquired as part of the DC Geographic Information System (DC GIS) and captured at 0.3-meter pixel resolution (approximately 1-foot). A companion downloadable mosaic is available as a compressed MrSID format.

This dataset contains georeferenced aerial imagery from 1927 and 1930 covering the District of Columbia. The original photographs were created as part of early aerial survey efforts and are held within a combined National Archives and Records Administration (NARA) catalog entry (NARA ID 139056920), Record Group 328. The images were scanned by the National Capital Park and Planning Commission, Federal Projects Planning Division (ca. 1926–ca. 1952). A multi-agency collaboration—including the Historic Preservation Office, OCTO, DHS, OP, DOEE, DOH, and FEMS—completed the georeferencing and mosaic development. As part of this effort, the team georeferenced and cataloged the full 1927 aerial photo series of the District, derived from more than 700 high‑resolution image scans. The resulting mosaic and index provide a historic baseline for land use, urban development, environmental analysis, and cultural resource research.
