Project Overview

Processed LiDAR point cloud data into actionable terrain products for a land development project. The deliverables included digital elevation models, cross-section profiles, thematic maps, and a 3D printable terrain model for stakeholder presentations.

The project enabled the development team to visualize and understand the terrain before breaking ground, improving planning decisions and stakeholder communication.

The team walked into the planning meeting with a physical 3D terrain model and print-ready maps, enabling clearer stakeholder communication.
