Extents of historical aerial imagery collections in Canterbury held by Environment Canterbury.
Note:
the historical aerial image collections layer is a work in progress layer and does not fully represent the entire collections.
also the aerial image is usually in hard copy (i.e. photo) and generally is only geo-located in a general area that the film was taken and scanned at a low quality scan approx 300 DPI.
extents do not represent accurate representation of the film extent.
surveys that were taken by NZAM, we have added their extents from LINZ LDS service here CCBY LINZ
