What is Photogrammetry?
Photogrammetry is the science of creating complex models with 2D images. While a rather broad definition, these models can take numerous forms. Here at KOALEIA Productions™ we specialize in aerial photogrammetry techniques such as surveying, mapping, orthomosaic imaging, and 3D models. The background pictured here is a depth map of an old Nevada mining complex.
Case Study #1, Example 1
In the Seven Troughs -an abandoned mining complex in Nevada- there well over a hundred mineshafts that descend straight down. Many of these are unmarked with no surrounding signs of a potential mineshaft and pose a serious safety risk. Here KOALEIA Productions™ flew over the area with a drone to create a high resolution orthomosaic view accurate to ±8" from an altitude of 600ft AGL.
Case Study #1, Example 2
Along with creating high detail orthomosaic images we're able to generate topographical maps to highlight changes in elevation. Pictured here is the same part of the Seven Troughs mining complex as pictured above, however, this is the topographical version. Within the highlighted areas two separate anomalies can be seen. Visiting the site on the ground presents two large 14-20' deep mineshaft otherwise invisible from ground level.
