ASPRS - Presentation on Mobile Mapping

Baker’s resident LiDAR Scientist, Dr. Srinivasan “Srini” Dharmapuri, presented a paper on Urban Surveying using Mobile Mapping and its Related Complexities at ASPRS 2012 Annual conference in Sacramento, CA on 3/22/12.

The conference theme, Imaging and Geospatial Technologies – Into the Future showcased more focused discussions on various geospatial technologies including mobile mapping using LiDAR. Srini’s presentation conveyed the project life cycle for a typical Mobile Mapping/LiDAR project, and highlighted the key complex areas in executing project in urban conditions. The diverse group of international attendees included prominent individuals from the public and private sectors, as well as academia.

As Baker's resident LiDAR Scientist, Dr. Srini is responsible for application development, QA/QC methodologies, technical writing, improving processing efficiency and other related LiDAR (static, mobile and aerial) activities. Also presently, Srini is the Chair of the ASPRS Mobile Mapping Committee involved in arriving at the “best practices document for Mobile Mapping”.

If you have a topic for Srini to write about, please leave it as a comment and we'll include it the Ask the Doctor series.

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.
