aerial survey pre planning construction

The Photogrammetry process allows for easy access to a geographically accurate model with the measurement accuracy being ± 20mm. The drone travels across the site in a grid formation with the second grid being perpendicular to the first to create a 3D map. The drone takes roughly 500 images per 12 acres, meaning about 1 image per 3 seconds. This can be adjusted depending on the detail required. For a map of this size, the process takes about 25 minutes. It takes around 2 to 5 hours to process data on software.

LiDAR, or Light Detection and Ranging is a sensing camera that uses a pulsed laser to calculate the exact distance of an object from the Earth’s surface. These light pulses from the laser, as well as the GPS and scanner of the LiDAR instrument generate Three-Dimensional information about the shape of the Earth surface. This system allows for the mapping and examination of natural and manmade environments with accuracy of ± 0.5mm. As the technology of LiDAR advances, LiDAR modules are becoming smaller, allowing for integration with drone systems, providing surveys with accuracy like never before

UAV’s can efficiently cover large and difficult to access areas of land and provide an accurate way to collect and analyze data from the air

Over the last 50 years or so health and safety rules have made traditional surveying more of a challenge especially where machinery and building activities limit what the proffessional is allowed to work safely. This can create problems for site managers planning and directing the survey requiremnets around all the excervation work, machines and workmaen doing other jobs. Aerial surveying and mapping solves all these problems and her in Melboune and Victoria wide, Skynet Video is able to perform aerial surveys for:

• Pre-site planning
• Radically shortening design process
• Document site safety
• Analysing sites digitally
• Infrastructure and asset inspection
• Export surveys to BIM/CAD software
• Construction project tracking
• Topographical surveys
• Stockpile measurement
• Cut and fill calculation
• Elevation profile estimation
• Accurate haul cost estimate
• Overlay engineering drawings on survey
• Quality inspection/management of assets
• Fly-throughs
