High Resolution Digital Elevation Models (DEMs) from LiDAR.

Professional elevation models at any scale—from a single construction site to the entire US. We deliver survey grade DEMs from precise LiDAR datasets built to your specification.

DEM Product Types

ProductDescriptionWhat It ShowsKey Applications
DSM (Digital Surface Model)Complete surface capture including all featuresTop of buildings, tree canopy, infrastructure, and ground3D city modeling, telecommunications planning, solar analysis, Line-of-Sight (LoS)
DTM (Digital Terrain Model)Bare earth elevation with all surface features removedGround surface only - no buildings or vegetationFlood modeling, earthwork calculations, watershed analysis
nDSM (Normalized DSM)Height above ground for all features (DSM minus DTM)Relative heights - buildings, trees, structures above groundBuilding extraction, vegetation management, change detection

Seamless, Survey-Grade Output

Seamless multi-source LiDAR fusion showing continuous elevation model

Seamless Multi-Source Fusion

Multiple LiDAR datasets are intelligently merged into a single, continuous elevation model with no visible boundaries or processing artifacts. Our fusion algorithms ensure centimeter-level vertical accuracy is maintained across dataset boundaries, delivering professional-grade output ready for engineering analysis, volumetric calculations, and regulatory compliance.

Professional-Grade Elevation Products

Our nDSM products deliver precise height measurements critical for infrastructure planning, volumetric analysis, and change detection. Every pixel represents accurate elevation data suitable for engineering calculations, regulatory submissions, and operational decision-making. From telecommunications tower siting to flood risk assessment, these are analysis-ready products that meet professional standards.

Technical Differentiation

LiDAR vs Satellite Technology

LiDAR technology penetrates vegetation canopy to capture true bare earth elevations. This fundamental advantage enables accurate flood modeling, infrastructure planning, and terrain analysis in areas where satellite-based products simply are not fit for the task.
