Negatives in the Archive were originally held as two separate collections: surveys flown on behalf of the Crown and private surveys flown by New Zealand Aerial Mapping (NZAM). All materials in the Archive are under Crown copyright and WSP on behalf of LINZ manages the Archive. More information on the Crown Aerial Film Archive and historical imagery scanning project can be found here.
Access to the images
Abley’s Retrolens website provides an interactive search interface for viewing and downloading many of the photos in the Archive. Although these are at a lower resolution than the original scans, the downloads are suitable for most general purposes.
Full resolution scans, Survey charts, Calibration files and images not on the Retrolens website can be requested by emailing [email protected] with the subject line: “Historical Imagery”.
WSP Photosales can provide, Oblique Photographs and Ortho-rectified geo-referenced images, for more information get in touch with us.
What is an oblique photograph?
Falling under aerial photography, typically an oblique photograph will be taken with the axis of a camera between the horizontal plane of the ground and the vertical plan of perpendicular to the ground.
There are two types of oblique options - high and low oblique. High oblique photographs will include the locations horizon, a low oblique photograph will show only the surface of the earth.
What is Ortho-rectified imagery?
Geometrically corrected, unlike an uncorrected aerial photograph, an orthophoto can be used to measure true distances as you would a map. Commonly used in planning and mapping software Ortho-rectified images are used for geographic referencing. The process of ortho-rectified photography removes the effects of image tilting and terrain effects for the purpose of creating a horizontally correct image. Images are placed in their true position when orthorectified.
