Engineering-Grade Terrain Models, Aerial Mapping, and Spatial Data for Site Design
Terrain & Surface Modeling
Accurate terrain understanding is critical before design begins. Horizons Mapping develops design-grade terrain and surface models that help engineers and developers evaluate grading, drainage, and site feasibility early in the project lifecycle. Using aerial photogrammetry, survey-controlled ground control points (GCPs) and independent ground checkpoints, and LiDAR datasets, we produce reliable digital terrain models, breaklines, contours, and earthwork quantities that support confident feasibility analysis and engineering design workflows.
• Digital terrain models (DTM / DEM)
• Surface modeling for grading and drainage analysis
• Breaklines, contours, and terrain extraction
• Earthwork quantities and volumetric calculations

Data Acquisition & Mapping
Reliable terrain modeling begins with high-quality spatial data. Horizons Mapping integrates aerial photogrammetry, survey-controlled ground data, and LiDAR datasets to produce accurate base mapping and site datasets that support engineering analysis and land development planning.
• High-resolution orthomosaic imagery
• 2D & 3D topographic data collection
• Integration of public elevation datasets (USGS, LiDAR, etc.)
• Ground control and survey data integration
• Terrestrial LiDAR scanning for detailed site capture
