Kucera LiDAR Data

Kucera International Inc. provides LiDAR services with our company owned and operated Leica ALS60 LiDAR system.

Advantages of this system include variable flight altitude (656′ to 16,404′) cross-track swath width, laser scanning rate (max 100 Hz), and laser pulse rate (max 200 KHz). The LiDAR laser is integrated with a state-of-the-art Inertial Position and Attitude System (IPAS) and at ground base stations to provide the highest degree of positional and orientation angle accuracy needed for terrain surface modeling.


When performed in conjunction with an aerial photography survey, the LiDAR flyover is typically performed in the morning and evening hours, thereby reserving the optimal sun angle period for the photography survey while ensuring that the LiDAR survey is completed within the shortest possible time with consistent terrain conditions. Within hours of each flight session, both the airborne GPS/IMU and laser return data components are given an initial quality control check/accuracy verification.

The ALS60 system provides four range returns as well as intensity return measurements. The range returns are processed to “bald earth” digital terrain/elevation models and other forms of digital height data (e.g., tree canopy, obstruction heights) using Terrasolid’s LiDAR dedicated TERRASCAN software.


During the photogrammetric review, breakline, skeletal lines, spot elevation, and other height data is added to the LiDAR DEM as needed to support intended applications, such as contour generation, orthophotography, hydrologic modeling, volumetric calculations, highway corridor planning, and power transmission line mapping.

The LiDAR DEM/DTM data is provided in all standard GIS/CAD compatible or organization specific (e.g., FEMA) formats, including ASCII mass point files, TIN models, and contours. The delivery includes an accuracy verification/quality control inspection report and metadata in the client-specified format.
