Video: Unmanned Aerial System over Stockpiles

Footage taken from an Unmanned Aerial System over aggregate stockpiles at a mine. UAS are being tested in many ways to explore their ability to improve acquisition and efficiency. In general, UAS are more cost efficient with projects that have a small project area and are within a reasonable travel radius.Learn More

Video: 3D Taum Sauk Reservoir

The data for this imagery was collected from a helicopter during construction of the reservoir.  Oblique images were used along with computer vision software to reconstruct a 3D surface and rectify the images.Learn More

Video: 3D Levee from Mobile LiDAR

This mobile LiDAR was collected with a  Trimble MX8 mobile spatial imaging system at a rate of 600,000 points per second.  Digital Terrain Models can be created from this data at survey grade accuracy and can be used to create cross sections and contours.  Other assets such as paint marking and signage can be semi-automaticallyLearn More

Video: Automatic Seamline Placement (Vector)

This video shows seamline generation over building footprints. Our proprietary seamline placement software detects building edges automatically, enabling different images to be combined through areas of lower interest, thereby keeping buildings intact (rather than have a seamline run through a building). The effect is a clearer depiction of an area’s intact buildings.Learn More

Video: Automatic Seamline Placement (Raster)

This video shows seamline generation over a digital orthophoto image. Our proprietary seamline placement software detects building edges automatically, enabling different images to be combined through areas of lower interest, thereby keeping buildings intact (rather than have a seamline run through a building). The effect is a clearer depiction of an area’s intact buildings.Learn More
