Photogrammetric surveyors specialize in the science of obtaining reliable spatial information from photographic images. Photogrammetrists analyze aerial and terrestrial photographs to obtain information about physical objects and the environment. The most common utilization of photogrammetry is in the production of base maps from aerial photography. Mapping generated using photogrammetry provides a cost-effective method of establishing an accurate digital base for such things as urban planning, terrain analysis and forest management. Photogrammetry can be used for landfill or gravel pit monitoring, determining the location of ore bodies or determining proposed locations for utilities, such as pipelines and transmission lines.
There are also many uses for non-aerial or close-range photogrammetry. These include digital modeling for architectural restoration, medical imaging for forensic sciences and reconstructive surgery, data collection for structural stability studies of bridges and hydroelectric dams, and the documentation of traffic accidents and crime scenes by police departments.
