Photogrammetry

Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring and interpreting photographic images.

Photogrammetry uses methods from many disciplines, including optics and projective geometry. Digital image capturing and photogrammetric processing includes several well defined stages, which allow the generation of 2D or 3D digital models of the object as an end product.
​
By accurately geo referencing known locations within the images, we can very accurately map underwater ecosystems for later analysis. Capturing the same area over a set period of time allows us to measure environmental changes such as individual coral growth, seagrass bed changes or even rate of coral bleaching due to climate change.
