Airborne LiDAR

We get your point. In some cases, billions of them.

From PTC mapping to the latest FERC rulings and line re-ratings, our clients rely upon LiDAR mapping to support their enterprise. LiDAR surveys must be complete, correct and most importantly, delivered on time.  Our experienced team of professionals and technicians understand these needs and are dedicated to delivering the quality and value you expect.

SAM's airborne LiDAR mapping services include aerial data acquisition from fixed-wing aircraft, helicopter, and unmanned aerial systems (UAS). With multiple data processing software systems that allow us to tailor LiDAR data processing to meet your specific needs, our extensive network, processing and people-power offers a scalability of resources to ensure quality and timely delivery of your airborne surveying products.

LiDAR Acquisition
Utilizing fixed-wing aircraft, helicopter, and unmanned aerial systems we can collect LiDAR data to the meet the specific density and accuracy needs of your projects. The collected data is immediately processed and verified to confirm complete data acquisition coverage. Any seams, holes or other unwanted artifacts are quickly identified to assess the need for any data acquisition re-capture. Once approved, the data is both archived and prepared for production.

LiDAR Processing
SAM has dedicated LiDAR processing network, hardware and software resources. We have massive dedicated storage space for mapping projects, banks of process servers and CPU’s available for distributed data processing tasks, and multiple state-of-the-art processing workstations. SAM has numerous seats of LiDAR processing software, including the industry standard suite of TerraSolid and GeoCue products. SAM is skilled at producing LiDAR derived mapping deliverables in all industry-standard CAD formats.

LiDAR Data Classification and Feature Extraction
Using the latest data processing and classification software enterprises, our experienced technicians begin initial automated filtering and feature extraction to accurately collect all required data deliverables. Effective auto filter routines can produce very clean bare earth LiDAR. However, it is always necessary to complete a manual review and edit of the data. The manual edit process eliminates any remaining anomalies and misclassifications within the data set. Experienced LiDAR technicians review the data in GeoCue/TerraSolid software and make any corrections to the point classifications.

Benefits of Airborne LiDAR

  • Increased speed and efficiency of data collection
  • Higher point cloud data density and accuracy
  • Full integration with other mobile and terrestrial LiDAR data
  • More options related to data collection altitude, speed and coverage
  • Faster turnaround of airborne LiDAR for project applications
