Illinois Tollway - High Accuracy Mapping

Illinois Tollway - High Accuracy Mapping AeroMetric has completed 36 miles of High Accuracy Mapping along a portion of the I-88 highway in Illinois.

West Lynn Canal Orthophotography and LiDAR Project

West Lynn Canal Orthophotography and LiDAR Project AeroMetric mapped avalanche paths from their accumulation zones to the run-out zones at the shoreline of Lynn Canal.

Juneau to Skagway Access Road LiDAR & Orthophotography

Juneau to Skagway Access Road LiDAR & Orthophotography AeroMetric developed three-dimensional modeling of avalanche chutes and the proposed roadway corridor for the Juneau Access Road.


LiDAR technology offers one of the most accurate, expedient and cost-effective ways to capture elevation information. LiDAR data is directly processed to produce detailed bare earth models in a variety of formats including LAS, ASCII, ESRI and CAD. Typical horizontal accuracies range between 20.0 cm to 100.0 cm. Typical vertical accuracies range between 9.24 cm and 18.5 cm for fixed wing aircraft and 1.0 cm to 3.0 cm for helicopter platforms. Derived products include DEM, DTM, DSM, slope/aspect, topographic maps and planimetric detail.

Equipment & Capability

AeroMetric utilizes several platforms, most recently acquiring a state-of-the-art Leica ALS70. This ultra high point density corridor and wide-area LiDAR system is capable of achieving measurement rates of 500 kHz, and unsurpassed control over the scan pattern on the ground.

AeroMetric is staffed by some of the most seasoned LiDAR professionals in the industry. These specialists have extensive experience with all facets of LiDAR including applications development, sensor development, programming, survey, data processing, data acquisition, GPS and IMU process development and multi-sensor integration.


AeroMetric seamlessly integrates LiDAR data with other data sets, including orthophotos, multispectral, hyperspectral and panchromatic imagery. We can combine LiDAR with GIS data and other survey information to generate complex geomorphic-structure mapping products, advanced 3-D models/earthwork profiles, renderings of structures, and many additional high value mapping products.


LiDAR point clouds can be used to derive a wide variety of geospatial deliverables including:

  • Intensity images 
  • Breaklines
  • Digital Terrian Models
  • Digital Elevation Models
  • Digital Surface Models
  • Triangular Irregular Networks
  • Vegetation layer for analysis
  • 3-D Models
