LiDAR Mapping
Peter and Associates 3D Aerial Mapping Service utilizes the latest commercial UAS (Drones) and LiDAR equipment. Measuring approximately 1.28 million points per second with an accuracy of ±3cm, we can generate dense and accurate point clouds for all your inspection and mapping needs.
Along with SLAM (Simultaneous Localization and Mapping) we can use the lidar in a handheld configuration allowing us to access places the drone can’t, such as the interior of buildings, parking structures, restricted airspace, tunnels and underpasses.
Both of these solutions integrate with onboard cameras offering colorized point clouds for easy navigation as well as access to the raw photos for detailed inspections.
Why LiDAR vs. Traditional Surveying?
LiDAR based surveying and traditional ground-based surveying will both provide accurate measurements of the site.
Each method leverages on known or surveyed control points to align the data to the real-world utilizing GPS/GNSS accuracy. However, with LiDAR many more data points will be collected in a shorter time leading to faster data delivery as well as the bonus of an accompanying 3D map offering endless calculations. Also, no terrain is too difficult since our points are being measured from the sky rather than traversing the site on foot. Overall, with technology evolving everyday LiDAR is quickly becoming the ultimate survey/mapping tool.
What do we do with all this data?
Immediately following on-site data collection, a quick field check is performed to confirm accuracy. Back at the office the full file is processed, colorized and ground control points are added. From here, access to the 3D file will be emailed to you. In the 3D map you are able to carry out measurements such as height, distance, stockpiles, slopes, height profiles, area, water pooling as well as view high resolution photos of the site.
Additional Deliverables
If you're looking for more from your data, further processing is available. We offer digital elevation models, orthomosaics, planimetrics as well as power line systems-CAD processing.
D.E.M.
Digital elevation models strip away all buildings, vegetation and other surface entities leaving behind a bare earth model of the ground surface. From this we can output a topographic map with contours and breaklines if desired.
Linework
Planimetric linework will convert all your 3D data into planimetric points, lines, and polygons. This will be outputted in a SHP, DWN or DXF file allowing manipulation in your drafting/design program.
P.L.S. - CAD
Power line systems-CAD is used for the design and analysis of power transmission lines. Providing a detailed insight into the verification of line paths and clearances, as well as sag reports on the lines themselves.
This deliverable is meant to be a complete package with design data, analysis reports, and visual drafts, providing all parties involved adequate information to make informed decisions.
