LiDAR Data and Orbit GT


Now that you’ve got Gigabytes or Terabytes of processed Mobile LiDAR data, what do you do with it? Experienced end-users may have multiple tools to view and manipulate Mobile LiDAR data; but what about the average John Q. Public that doesn’t have tens-of-thousands of dollars to dump into software and training? To help our clients maximize their resources we’ve implemented a web-based solution on our BEAST environment (see Belly of the BEAST) that leverages the Orbit GT framework to link panoramic imagery, GIS/CAD features, and LiDAR point clouds into a single integrated solution that can be accessed from any of the most popular internet browsers.

By publishing the LiDAR data with Orbit end users are provided a user-friendly platform to view, collect, and interact with various forms of field-collected data. The configurable user environment typically contains two imbedded, user-scalable windows for an overview map (top section) and the panoramic imagery and LiDAR point cloud (bottom section). The overview map supports OpenStreetMap, which provides an excellent backdrop for the overlay of panoramic image locations and available GIS data. Similarly, GIS data can also be overlain on panoramic imagery / point cloud window(s), provided valid elevations are available in the GIS.


Other basemap functionality includes the ability to geocode addresses using Google’s geocoding engine, search by GIS object, and search by X,Y coordinates. The Search by Object tool is particularly helpful as it will search all attributes within the selected layer, not just on a single column.

The panoramic imagery / point cloud section also has a robust selection of tools through which the user can toggle on/off layers and interrogate GIS data, as well as the ability to open multiple viewing windows to simultaneously observe the same location from various perspectives. 360-degree pan/zoom functionality is standard, as are measurement tools including: positional location, distance, line (single and multi-segment), area, and volumetric calculations.

The beauty of the solution is the ease of use. Anyone that’s ever used an online map will be self-navigating and making meaningful observations within minutes – and all without any special software or any required training.

Stay tuned, I’ll share more content in the future about this and other technology being leveraged by our clients.

Regards,
Scott

What is Mobile LiDAR?

Mobile LiDAR (Light Detection and Ranging) systems are comprised of vehicle-mounted lasers, cameras and GPS/INS navigation systems to capture highly-detailed and accurate three-dimensional (3D) topographic information for surveying and engineering applications. Michael Baker International became an early adopter of Mobile LiDAR technology by acquiring our first system in 2009, with further expansions in 2014 and 2015 that increased our fleet to four (4) Optech Lynx SG1 Mobile LiDAR systems. Over that period our systems have completed more than 300 projects throughout 29 different U.S. States (and multiple countries), and encompassing hundreds of thousands of miles. Our project portfolio includes applications in roadway design, 3D modeling, railroad corridors, signaled intersections, utility infrastructure, asset management, pavement condition assessment and airport infrastructure.
