Our Technologies


Lidar (/ˈlaɪdɑːr/, also LIDAR, or LiDAR) is a method for determining ranges (variable distance) by targeting an object with a laser and measuring the time for the reflected light to return to the receiver. LiDAR can also be used to make digital 3-D representations of areas on the earth’s surface and ocean bottom due to differences in laser return times and varying laser wavelengths. It has terrestrial, airborne, and mobile applications.

Stratus utilizes LiDAR technology to create high-resolution maps, with applications in surveying, engineering, architecture, and forestry.

We use several processes and software to analyze, classify and produce relevant data pertaining to project specifics.


Photogrammetry /fō-tə-ˈgra-mə-trē/ is the science of making reliable measurements by the use of photographs and especially aerial photographs (as in surveying) to create 3D models, drawings, maps, and marketing materials, often used by surveyors, engineers and architects.

Stratus utilize high-resolution UAV mounted cameras to obtain high-quality RGB images. We process these images through complex software analysis, creating accurate geo-referenced 3D models, terrain data, geo-tiff files, and other industry-standard geo-based file formats. We use photogrammetry in conjunction with our LiDAR toolset to deliver on very demanding and specific projects.


Bathymetry (/bəˈθɪmətri/; from Ancient Greek βαθύς (bathus) ‘deep’, and μέτρον (metron) ‘measure’) is the study of underwater depth analysis within various basins. Bathymetric surveys usually show basin floor relief or terrain as contour lines (called depth contours or isobaths) and selected depths (soundings).

Bathymetric maps may also use a Digital Terrain Model and artificial illumination techniques to illustrate the portrayed depths.

Stratus uses unmanned small scale vessels equipped with onboard sonar and data acquisition equipment to obtain and produce high-quality basin topographic surveys. Typical uses for our clients include pre and post pond cleaning without dewatering and underwater / submerged infrastructure mapping.

GNSS Receivers

Global navigation satellite system (GNSS) describes any satellite constellation that provides positioning, navigation, and timing (PNT) services worldwide or regionally.

Stratus uses GPS and GNSS signals via a GPS/GNSS receiver and antenna to determine the form, boundary, position of objects or points in space relative to other forms, boundaries or points.

We utilize this technology in conjunction with all our aerial-based surveying, whether LiDAR, Photogromattery or during inclement weather conditions at which UAV flights become prohibited.


Our Equipment

  • InertialLabs RESEPI Lidar 720,000 returns/second – High accuracy lidar remote sensing payload.
  • Matrice 300 RTK with D-RTK 2 GNSS Base Station – Enterprise-level drone for our LiDAR payload.
  • Matrice 210 V2 RTK with D-RTK 2 GNSS Base Station – Enterprise-level drone for inspections and large-scale photogrammetry.
  • Phantom 4 RTK with D-RTK 2 GNSS Base Station – Our dedicated photogrammetry drone.
  • GeoMax Zoom 50 Total Station – Benchmark transfers, accurate measurements, and GPS-denied environments are where this piece of equipment shines.
