Technology moves fast – mobile LiDAR moves faster! This innovative mapping solution is game-changing survey technology. It completes data collection five times faster by incorporating the most advanced LiDAR sensors, cameras, and position/navigation to collect survey-quality point data, simply by walking or driving at highway speeds.


Our mobile LiDAR tools include a vehicle mounted unit and a wearable mobile mapping system. The use of LiDAR creates a complete dataset of location and features, meaning precise measurements and calculations for design, planning, or analysis can be available at your fingertips and ready for export to numerous platforms.

Mobile Unit

Our mobile LiDAR unit is one of the safest, accurate, fastest, and most efficient means to collect data. It's safe because the driver never needs to leave the vehicle during the collection process or impede the traveling public. It's accurate generating point clouds that feature pinpoint precision. It's fast and can reduce the amount of field work time from months to just days.

Wearable Mobile Mapping System

TWM is one of the very few firms in southern IL and MO to invest in this equipment! The NavVis is a wearable mobile mapping system that delivers 3D high quality images of any site in every direction to capture a full 360-degree panoramic view, from interior spaces to exterior locations. A key benefit is the simultaneous Localization and Mapping (SLAM) technology that allows for real-time updates and ensures all necessary data has been captured before leaving a project site.

Mobile LiDAR Improves Accuracy, Quality, & Safety

Efficient. Effective. Economical. TWM has the resources to collect highly detailed site conditions and capture data on almost any project. In addition to state-of-the-art equipment such as mobile LiDAR to collect data at highway speeds, our firm uses high-definition 3D laser scanning/terrestrial LiDAR for precision data and UAVs for aerial LiDAR photogrammetry/imaging. By utilizing this technology, TWM can help design professionals save time, increase revenue, minimize risk, and correct conflicts prior to construction.

  • Can be operated day or night

  • Collects miles of data point measurements remotely, in one pass

  • Collects complete topographic data on sidewalks, pedestrian ramps, and for streetscaping, resurfacing, and pavement rehabilitation

  • No return trips for additional topography or checking against disputes

  • Vertical and horizontal accuracy

  • Ideal for highway, sea, or railway projects


  • Traffic analysis

  • Road surface and pavement conditions

  • Curb detail

  • Utility locating

  • GIS mapping/asset management

  • Bridge structures/under deck

  • Vertical face of buildings

  • Ground objects


TWM separates itself from the competition by using state-of-the-art technology for data collection. Besides traditional surveying methods, we own, operate, and test reality capture tools daily, including mobile/terrestrial LiDAR units, UAVs, and the accompanying software.

We have the resources to provide multiple, fully-equipped survey crews matched to a project’s needs. Our expertise includes boundary, ALTA, right-of-way, construction, and engineering surveys.

This reality capture data tool uses an advanced high definition laser scanner to collect millions of data points in a fraction of the time of conventional methods.

UAVs are equipped with sensors and cameras for scanning data. Our drone team, who are licensed remote pilots, gather this visual data of job sites to create accurate 3D models for planning and design.

For water dependent projects, TWM offers a highly skilled team of professionals who measure and map water bodies and shorelines to capture full coverage and data.

Combining visual features with supporting databases, this digital mapping method is used to maintain utilities, monitor transportation conditions, and other activities.

TWM employs various detecting equipment to survey and map underground utilities and log utility depth and offset. Data is easily exportable to GIS, CAD, and other applications.

Also known as construction staking, TWM’s services use robotic total stations, 3D laser scanners, and digital levels to provide accurate construction plan data.


That’s our company mission and our promise to you. Our success is built upon a solid reputation for getting the job done right. One thing we are particularly proud of is approximately 95% of TWM’s work comes from repeat business. We believe our resolution of challenges sets us apart, and based on our level of repeat business, we think our clients will agree.
