Geology - Photogrammetry
Using close Photogrammetry is a strong benefit when determining the measurements of inaccessible geological features. Most geological information is provided via maps or cross sections that are typically 2D. The 3D geometry of a geological structure can help to quantify a number of geological processes.
The measurements acquired from these pictures will help to monitor, research and plan with regards to geological and environmental locations / situations.
In addition, there are situations that restrict conventional measurement capabilities or the capturing of precise measurements are not possible. These situations involve:
- Remote areas
- Dangerous locations
- Comparative analysis involving “pre-event” and “post-event” situations (such as fire, explosion, flood, etc...). DCM can use historical pictures of “pre-event” situations to complete comparison.
There are two types of Photogrammetry classifications. DCM uses the first classification called Close-range Photogrammetry. Close-range Photogrammetry uses non-specific, everyday cameras to create drawings and 3D models of items, locations or buildings. Historical pictures can be used to provide great detail and modelling opportunities.
The other classification is Aerial Photogrammetry which typically focuses on topographic products such as terrain or topographic maps. If you do not already have images for this purpose we can arrange proper flight parameters to ensure proper coverage and accurate results.
DCM is capable of determining measurements using Photogrammetry via two processes. The first includes processing from pictures to provide scientific conclusions of measurements of the item in question. These pictures can be historic in nature and age or of recent development.
The second process involves DCM attending a scene or location and take pictures as a component of the service for analysis immediately or at a later date. DCM offers an on-demand service whereby pictures are taken of the item in question and stored in a secure database until such time that measurement analysis is required (such as after a fire or development of virtual promotion).
