| Purpose | Historical imagery was aquired from a variety of sources. Since 1996, NYC OTI has captured orthophotography. Starting in 2004, aerial imagery has been captured on a 2 year cycle. These imagery provide: a basis for the planimetric updates; a visual record of the City at specific intervals; a visual base for capturing and recording additional spatial data; and allow for a visual analysis of the City. |
| Description | Raster file of vertical aerial imagery covering New York City. Imagery is captured every 2 years during spring/summer months and corrected through computer processes to remove distortions caused by elevation changes and camera angles. |
| Source(s) | New York State Statewide Digital Orthoimagery Program |
| Publication Dates | Data: See Data Specifications for specific capture information Last Update: 2022 Update Frequency: Aerial imagery has been captured every 2 years since 2004. |
