Photogrammetrists work by creating maps, surveys, and other scale drawings and schematics based on photography, such as maps for companies in the energy business which are involved in raw material extraction. Photogrammetrists also work in the field of architecture and surveying and are very useful in designing large-scale projects from photos and surveys.
Photogrammetrists use a variety of disciplines in their work. One of the first problems they must solve in any new task is to find ground features in existing photos which can be used to reconstruct scale for dimensions like distance and height. They typically use a variety of advanced arithmetic and geometric formulae to establish scales across groups of photos of a particular landscape or land mass.
Computer fluency is also a key for a photogrammetrist. Once he/she has established scale, the creation of scale drawings and maps based on these calculations will typically require the use of topographic computer-aided drawing (CAD) software. They will be expected to account for distances and heights of various natural landscape details and show them in close relation to one another. For map-making, this can be incredibly important in areas affected by frequent flooding or earthquakes. In architecture, the work of a photogrammetrist can be vitally important for a design team in visualizing buildings and structures and understanding how they can fit within a given spacial region.
Photogrammetry typically requires at least a university degree in a cartographical discipline, and dedicated degrees in this field are becoming more widely available. Photogrammetrists may also be required to carry certification (either for this field specifically or as surveyors) in many jurisdictions, and continuing education and training are important to maintain employability within this career track. Most photogrammetrists work in large offices or studios with access to commercial imaging and drawing equipment.
