MMM performed an Unmanned Aerial Vehicle (UAV) survey to create a digital terrain model and an aerial image map for the Ministry of Highways and Infrastructure, Saskatchewan
- Survey carried out without having to post flag persons on the highway, minimizing disruptions to road operations
- Covered a 33 linear km and a 100-m wide swath of Highway 7, with flights conducted over a period of five days
- UAV survey methodology ensured all features were picked up at one time, reducing or eliminating the requirement for return field visits.
- Delivered high-resolution (5 cm pixels) aerial imagery of the site, a digital terrain model (5 cm accuracy) with 1 m point spacing, and cross-sections along the highway at defined intervals
- Survey allows for specific features (edge of road, centerlines, road markings, condition of roads and ditches) to be picked out from the imagery and the digital surface model.
- Data can be filtered to various grid sizes to allow for ease of use in assorted software packages.
- road surface and cross-section survey
- digital terrain model creation
- high resolution imagery collection
