Aerial Site Survey Integration

Project Overview

This initiative focused on optimizing the bridge between raw aerial drone data and construction-ready CAD documentation. By leveraging reality capture, I established a streamlined pipeline that transforms complex site survey data into high-precision topography models, ensuring greater accuracy for municipal utility and grading projects.

Stack & Execution

The technical workflow was developed using Dronelink for flight planning and reality capture, with data processed for integration into AutoCAD/Civil 3D environments. Execution focused on data integrity and georeferencing precision, ensuring that site surveys aligned with established engineering standards and minimized errors during the initial grading and layout phases.

Role & Contribution

Acting as both Pilot and Lead Designer, I managed the end-to-end reality capture process—from flight mission planning to data processing and CAD integration. My role involved ensuring all aerial survey data met strict tolerance requirements, providing accurate baseline topographical information essential for subsequent infrastructure design and site development.

Key Challenges and Technical Solutions

Challenge: Non-Perpendicular Alignment Skew

Solution: Configured multi-baseline corridor regions and assigned custom curb return alignments/profiles. Used horizontal width and vertical elevation targets along curb returns to ensure smooth, natural pavement transitions through the skewed quadrants.

Challenge: Primary Crown and Secondary Elevation Tie-Ins

Solution: Maintained the primary roadway’s continuous crown profile through the intersection while dynamically matching the secondary roadway approach grades to the edge of the primary lane, preventing abrupt grade breaks and drainage pockets.

Challenge: Terrain Daylighting and Surface Integration

Solution: Applied subassembly daylighting targeted to the Existing Ground (EG) surface across varying side slopes. Extracted corridor feature lines to generate a refined finished ground (FG) surface with smooth contour continuity.
