The Use of Aerial Photographs in New Zealand Archaeology.
By G. Blake Palmer.

Air-photography, a proven aid to archaeology in England, Italy and elsewhere, is applicable to similar New Zealand problems.

Existing New Zealand aerial-mapping photos contain valuable archaeological evidence, some of it new.

Low altitude “verticals” over “archaeological areas” will yield more valuable results and should reveal crop-sites—differential growth of maturing crops over areas of former soil displacements. (Crop sites elsewhere have revealed timber structures—Woodhenge 1500 B.C., Celtic field-systems, 450 B.C. to 450 A.D., hut circles, etc.)
