Product Description:

Oblique aerial photography is an airborne survey technique whereby a professional-grade digital SLR camera is used to capture images from the side of an aircraft.  This side angle of view distinguishes oblique imagery from the more traditional vertical imagery captured for mapping purposes.

The Environment Agency (EA) have been capturing oblique aerial photography during events such as flooding since 2010, and have now collated an archive comprised of over 30,000 individual images.

All images are supplied in JPEG image format, containing EXIF metadata within the JPEG image which provides details such as:

  • A date and time stamp of when the image was taken
  • A geotag stamp of the location (latitude and longitude) of the aircraft, from the GPS
  • The heading of the aircraft, from the IMU (inertial measurement unit)

All images are captured from the left-hand side of the aircraft which enables an approximate image view angle to be calculated.

Due to the short nature of incident response surveys, this imagery is often captured during low light conditions to provide a snapshot of the situation on the ground during a specific incident, and therefore the image quality can vary.  Due to this, the archive has been split into two types of oblique images, both of which are available to order through the Geospatial data service as separate layers:
