High-resolution Civil LiDAR Data Products


One high-resolution data collection meets multiple stakeholder needs.

LiDAR Products Overview

Base CalibratedPoint Cloud Data

    The base level product consists of an unclassified (non-attributed) point cloud that is calibrated to meet a specified accuracy. From this stage, the point cloud can be processed into numerous downstream products.

Base Classified Point Cloud Data

Base ClassifiedPoint Cloud Data

    The base classified point cloud has only terrain (ground) points classified and can be used for terrain surface modeling, volumetric, topographic, geology, environmental, and other applications.

Enhanced Classified Point Cloud Data

    The enhanced classified point clouds are calibrated and classified with terrain (ground points), vegetation, and infrastructure (buildings) for expanded applications for topography, geology, environmental, volumetric, forestry biomass, urban planning, 3D building models, utilities, and transportation.

Intensity Raster DSM

Intensity RasterDigital Surface Model

    The intensity or “reflectance” raster image, as it is referred to from a Geiger-Mode sensor, can be processed at various resolutions up to the native resolution of the LiDAR point cloud. This resolution can be specified per customer request and is used for planimetric mapping, feature extraction, and other remote sensing applications.

Bare Earth DEM

Bare EarthDigital Elevation Model

    A bare earth DEM is a raster or elevation grid product developed from the bare Earth point cloud. Typically, this is a lightweight file and is a popular format for use in many CAD and GIS application programs. Its uses include terrain surface modeling, volumetric, topographic, geology, environmental, and other applications.

Hydro-flattened Bare Earth DEM

Hydro-flattened Bare EarthDigital Elevation Model

    A hydro-flattened bare earth DEM is a raster or elevation grid product developed from the bare earth point cloud. It incorporates breaklines to flatten water body (lake and pond) elevations and create monotonic behavior in rivers.
