Photogrammetry (2D & 3D Mapping)
Photogrammetry is defined by the American Society for Photogrammetry and Remote Sensing (ASPRS) as “the art, science, and technology of obtaining reliable information about physical objects and the environment, through processes of recording, measuring, and interpreting imagery and digital representations of energy patterns derived from noncontact sensor systems” (Colwell, 1997:3).

How We Do It
In mining, photogrammetry can be used for stockpile monitoring, highwall surveying (derived data is normally used by geologists and geotechnical engineers) as well as backup surveys for blasts and spoil discharge.
Aerial photogrammetry also has the possibility to be implemented into GIS systems for visualisation, modelling and analysis purposes.
Mining
Construction
Geodata that is tagged in each image from the drone allows us to create "digital-twins" of structures or areas of land. Other data in the images provided can help create infromational 2D map layers regarding elevation, vegetation health, DSMs, DTMs, and DEM exportables that work directly in GIS and CAD software.
Photogrammetry is rapidly replacing other outdated technology used in the construction business for years. You can improve your business efficiency by incorporating photogrammetry into your day-to-day operations. Many innovative companies have already adopted this technology and are reaping the rewards of fast and accurate data.
Land Development
In Land Development proper photogrammetry practices save time and money when utilizing key features to LaSens service such as volumetrics and elevations. As in mining volumetrics is a great way to monitor stock pile and spoil amounts.
All land development projects need surveys. Sometimes those surveys can take weeks or months to get back. We can collect and deliver survey grade data in just a few days.
Agriculture
Agriculture is another industry that has taken advantage of the benefits of photogrammetry. Farmers can now monitor vegetation encroachment in their fields, conduct accurate plant counts, and determine areas of uneven irrigation.
Ranchers too can also benefit by being able to conduct accurate cattle counts over extremely large areas of land.
APPLICATIONS
2D / 3D Mapping and Modeling
LaSen UAS uses drones to collect imagery and data to create an aerial map and model view of large areas. The maps and models generated are interactive to the user allowing them to conduct specific calculations such as volumetrics, elevations, counts, area, perimeters, and cut and fill analysis.
Industries such as a local utilities waste management division could use our photogrammetry services for cut and fill analysis, density and volume calculations, slope management, and detecting available airspace to optimize compaction.

Our 3D Models are Interactive
We understand that data collected is only as good as the equipment collecting it. That is why we use Aeropoints high accuracy ground control points. So we can achieve an accuracy of within 3cm, which surveyors, land developers, and land managers of waste systems look for..
Change Detection
A powerful tool in our photogrammetry service is change detection. Change detection allows us to compare maps of the same location over different periods of time. This makes comparing changes in elevation, cut and fill analysis, or even the progress of a project easier than ever before.
