Project Overview

Project Summary

Reality IMT completed a mobile LiDAR corridor survey for approximately 1.4 miles of urban roadway containing 19 signalized intersections. The client required more than a registered point cloud. The final scope included engineering-ready Civil 3D data structured around the client’s internal production standards.

The roadway remained fully operational during acquisition. Heavy traffic, active construction zones, congested intersections, and temporary obstructions created difficult visibility conditions. Reality IMT planned the field effort to maximize coverage of pavement edges, curb lines, medians, sidewalks, signal infrastructure, and other visible roadway features while maintaining safe mobile operations.

After collection and processing, Reality IMT worked collaboratively with the client’s engineering team to refine layer naming, feature extraction, 3D linework, COGO point structure, and Civil 3D formatting. This transformed the assignment from a conventional point-cloud delivery into a repeatable engineering-data workflow.

Client Need

Project Challenge

The client needed a usable civil-design dataset rather than raw reality-capture data alone. The deliverables had to integrate with an established engineering workflow and remain useful for design, asset review, and future corridor planning.

Active Urban Traffic

Heavy traffic and continuous roadway operations limited ideal visibility and required efficient mobile acquisition.

Construction and Obstructions

Active construction, temporary barriers, and congested intersections affected line of sight to selected roadway features.

Client-Specific Civil 3D Standards

Feature extraction, layers, point organization, and file structure had to match the client’s production methods.

Reality IMT’s Approach

From Mobile LiDAR Capture to Engineering-Ready Civil 3D Data

Reality IMT structured the work as a coordinated capture, processing, feature-extraction, and client-review workflow rather than a simple point-cloud handoff.

Corridor Planning

The team reviewed the alignment, intersections, traffic environment, construction activity, and visibility limitations.

Mobile LiDAR and Imagery

The roadway was documented while remaining open to traffic using mobile LiDAR and synchronized GPS imagery.

Registration and Processing

The data was registered, organized, and prepared for detailed feature extraction and verification.

Civil 3D Workflow Development

Reality IMT refined layers, feature lines, COGO points, and file structure with the client’s engineering team.

Project Outputs

Deliverables Provided

Georeferenced Corridor Coverage Map

Interactive aerial map showing the complete Mobile LiDAR corridor survey path, capture locations, and project coverage used to verify roadway data collection and field completeness.

Interactive 3D Corridor Viewer

Web-based 3D corridor viewer linking georeferenced Mobile LiDAR data with synchronized street-level imagery for engineering review, visual verification, and remote asset inspection.

Street-Level GPS Imagery & Asset Verification

GPS-referenced panoramic imagery synchronized with roadway mapping data, allowing engineers to inspect intersections, roadway assets, utilities, signs, and existing field conditions without returning to the site.

Registered LiDAR Point Cloud

Processed LAS and RCP files preserving the measurable three-dimensional corridor dataset.

Client-Specific CAD Layers

Layer organization and naming refined to match the client’s production standards.

Web-Based GPS Imagery

Interactive street-level imagery with mapped positions for visual verification of roadway assets and field conditions.

Project Outcome

A Repeatable Mobile Mapping and Civil 3D Production Workflow

The completed project provided the client with more than field data. Reality IMT delivered a coordinated engineering dataset that could be used directly within the client’s Civil 3D environment.

The collaborative refinement of feature extraction, layers, COGO points, and file formatting established a repeatable framework for future roadway and transportation-corridor assignments.
