6 Benefits of Using Photogrammetry for Mapping and Surveying

If you are still using standard mapping and surveying methods, it is time to make the switch to photogrammetry. Here are 6 benefits of photogrammetry to convince you.

Photogrammetry refers to the process of taking measurements from photos, by analysing the surface points of an object. Once the measurements of a series of overlapping images are taken, a computer software is used to stitch the images together, not just as a 2D image, but also as a 3D model. These models/images are used to measure areas, lengths and volumes of structures and other points of interest. The term photogrammetry is the combination of the words “photo” and “meter”. It simply means the measurements taken from photographs.

Today, photogrammetry has become a much sought-after surveying and mapping technique that is used for site planning, topographic mapping, earthwork volume estimation and image-based mapping to name a few. Reliable information about physical objects and the complete environment is taken into account. Terrestrial and aerial photographs are taken and then recorded, measured and evaluated.
