Aerial photography is a rich source of geographic information, supporting research, planning, discussion, decision making and instruction in all manner of activity related to the land and the environment.
Photogrammetry, or stereo mapping, from aerial photography provides accurate and cost effective identification and measurement of terrain and topographic features, significantly reducing the need for field survey.
Orthophotos combine the visual information of aerial photography with the positional and scale accuracy of a map. They can be used on their own or in conjunction with mapping or other land information in a geographic information system (GIS), where they provide an extensive amount of visual data in an easy to interpret and cost effective manner.
NZAM’s experienced and dedicated photogrammetrists use high precision analytical stereo plotters and digital photogrammetric workstations.
