Unmanned Aerial Surveying
Digital Surface Model (DSM)
Using our Hypack NEXUS LiDAR UAV system or Pix4D photogrammetry software, SurvTech Solutions can create a highly accurate elevation models to capture natural and built features. DSM’s are useful in: telecommunications, urban planning and aviation planning scenarios.
Bare-earth Digital Elevation Models (DEM)
SurvTech Solutions software suit allows us to edit out vegetation and man-made features to create a smooth elevation model which can be useful in: hydrologic modeling, soil mapping, in addition to general Topographic and Planimetric mapping.
SurvTech Solutions also offers unmanned services for the purposes of asset inspection. We have worked closely with Flatwoods Consulting Group, and ecological consulting firm, to inspect communications towers and tall structures for Osprey activity.
Digital Orthophotography and Mosaics
Continuous pictures of terrain constructed by assembling a series of individual and overlapping images such that the perspective aspect of the picture has been removed. The Ortho-Mosaic can then be used as a planimetric map and imported into CADD or other Geographic Information System environments. SurvTech Solutions has been successful in realizing RMSE accuracies of fewer than one-hundredth of a foot.
SurvTech Solutions has effectively implemented our UAS program to include volumetric data collection reducing field time and overall cost.
Feature Extraction/Digital Mapping
SurvTech Solutions can save time, money and man-power by using UAS to collect survey line-work from orthophotography.
Infrared (IR) and Near-Infrared (NIR) for vegetation index and heat sensing
Being able to positively identify areas of heat/energy loss or unhealthy vegetation can better
Enable accurate and timely corrective action.
Used for aerial planning, logistics and real estate sales/purchases
Weather using our LiDAR UAV or photogrammetric software, SurvTech Solutions can create highly accurate three-dimensional “point-clouds” used for visualization.
Iris Plus Quad-Copter: A very stable and effective rotary platform, the 3DR Iris Plus can remain airborne up to 22 minutes and map 40-50 acres. With built in safety features and failsafe’s, the Iris Plus is the perfect tool for smaller aerial surveys. The 3DR Iris Plus uses the 16MP GoPro Hero 4 compact camera and a 16MP Canon HS320 Power Shot camera.
Event 38 E384 Fixed-Wing: Based on the tried and true Skywalker platform, Event 38’s E384 fixed-wing UAV can remain airborne up to 100 minutes, fly at 20 MPH and cover an area up to 600 square acres in a single flight. SurvTech Solutions uses the 28MP Samsung NX500 DSLR, 16MP Canon and 16MP Canon altered for NIR data capture.
HyPack NEXUS: From a very trusted hydrographic software company, HyPack has designed a Y6 form coaxial Hexacopter capable of both LiDAR data collection and photography for photogrammetric remote sensing. The NEXUS uses a Canon TI5 DSLR camera and a Velodyne LiDAR unit capable of acquiring three-hundred thousand points per second.
