Light Detection and Ranging (LiDAR) has revolutionized the acquisition of digital elevation data for large-scale mapping applications as organizations, both public and private, endeavor to utilize the most accurate terrain information for their decision-making processes. Merrick & Company has embraced LiDAR technology since 1997 and has successfully provided these highly technical data acquisition services to clients for a variety of applications including:

Contour mapping
3-D perspective analysis
Floodplain mapping
Vegetation mapping
Shoreline analysis
Corridor/route studies
Slope analysis

Merrick uses the most advanced LiDAR sensors on the market today. The firm owns and operates the Optech Pegasus HA500 and Orion C200, as well as the Leica ALS50-II+ and ALS50 laser scanners. These sensors are capable of emitting up to 500,000 laser pulses per second, which supports a wide variety of geospatial applications. In addition, each LiDAR system is co-mounted with a digital camera that supports the simultaneous collection of elevation data and digital imagery. This technical approach, coupled with the firm’s project experience and successful project management provides, clients with multiple benefits including:
  • The ease of an all-digital approach in acquiring, managing and analyzing large spatial data sets
  • Integrated flight management for greater efficiency
  • Multi-sensor integration for cost effectiveness
  • Integrated LiDAR and digital camera integrated with high-grade inertial measurement unit (IMU) and airborne global positioning system (AGPS) for high accuracy
  • Efficient utilization of Merrick’s aircraft fleet for improved project schedule management
  • Merrick Advanced Remote Sensing (MARS®) software suite for LiDAR visualization and data processing solution
