Light detection and ranging (LiDAR)

Our commitment to using the latest in geospatial technology has spanned over 30 years and continues to this day through the use of LiDAR technology. LiDAR has become a standard tool for Rice Associates on projects as it allows us to greatly enhance our survey capabilities and offer our clients increased safety, enhanced scheduling, and improved quality and accuracy.

Static LiDAR

For the past 10 years, Rice Associates has utilized static terrestrial scanners to map highways, bridges, tunnels, and buildings. LiDAR scanning supports many disciplines including architectural, structural, MEP, and civil. LiDAR provides 3-D spatial information as well as conventional survey mapping products. Point cloud data can be used to develop BIM models for use in conflict analysis for retrofit and rehabilitation projects, constructability review, and implementation planning.

Mobile LiDAR

Our in-house mapping services could not be complete without the addition of the Leica Pegasus:Two. This mobile mapping solution does not require dedicated or modified vehicles and allows our team to capture imagery and data from a vehicle-based platform at posted speed limits. Benefits of mobile mapping include rapid data collection, improved deliverable quality, and reduced field time.

Aerial LiDAR

Rice Associates also provides airborne acquisition and processing services. This technology uses a high-resolution laser mounted on a helicopter or fixed-wing aircraft to scan ground features. The data collected from the LiDAR can be used to generate a Triangulated Irregular Network (TIN) which is used to develop data sets, topographic maps, and bare earth models. This technology offers one of the most accurate and cost-effective ways to capture elevation information.
