Geology Applications with PhotoModeler

There are a number of applications in mining, quarrying and geology for PhotoModeler and PhotoModeler Premium. PhotoModeler Premium provides a very cost effective and efficient method for modeling the earth surface, cliff and exposed rock faces, stockpiles, and tailing piles.

One can extract dense point grids (similar to a laser scanner). In addition surfaces, contour lines, and measurements can be done on the resulting point clouds. With input of external control data you can geo-reference the project and the outputs. Far more cost effective than using traditional surveying methods!

Measuring volumes of stock and waste piles is a good application as well. This Volume Tip video shows how it is done.

Examples in Geology and Mining

  • mine reclamation
  • stockpile
  • open pit
  • hydrology

Mike Dunn, author of Recent Developments in Close Range Photogrammetry (CRP) for Mining and Reclamation, writes, "The mining/reclamation community depends on accurate mapping for almost all activities. Traditional ground surveys are totally adequate for small, uncomplicated jobs but at some point, the size and/or complexity of a project makes it more economical to have a site “flown” (mapped using aerial photogrammetry). Because of cost, most projects are only “flown” at the start and less often when completed. Changes during the project may be surveyed but in many cases aren’t worth it –negative cost/benefit, too dangerous, or inaccessible. AML complaint investigators can face similar issues. For example, monitoring a nuisance landslip to decide whether it is a true emergency. Close Range Photogrammetry (CRP) offers much potential for measuring features that can’t or aren’t being measured otherwise."
