Open LSEF – A Common Language for Extracting Information from 3D Point Clouds

3D Point Clouds are becoming ubiquitous – people collect them with scanners, with drones, and with phones. However, collecting the point cloud is now the easy part of the process. Features need to be extracted and identified from the data to provide context. While many tools are being created to extract features from 3D point clouds, there is currently no agreed upon definitions of how these 3D features are to be defined. This greatly limits the ability to transfer information between applications and utilize it in subsequent analyses. It can be frustrating to be a drafter (or Artificial Intelligence) trying to learn what curbs (or kerbs) look like if no one can agree whether flow line or back-of-curb is the defining feature. This GeoByte will present a new common language, OpenLSEF, that describes how features in 3D point clouds should be defined, by establishing definitions and terminology, products from providers can be standardized, designers can expect consistency, self-driving cars can share high-definition maps and tool-makers can focus on ensuring extraction algorithms return expected results. OpenLSEF is a user-created initiative focusing on standardizing extraction definition in the AEC (architecture, engineering and construction) field, as well as transmission, utilities and BIM (building information management). These are living standards relating to the meaning of extracted data, as opposed to simply focusing on actual file format standards. As such, OpenLSEF is data-format agnostic and is meaningful whether you deal in DWG, DGN or SHP files. The webinar will also include information regarding how to become involved in the Open LSEF Working groups.


Michael Olsen is an Associate Professor of Geomatics in the School of Civil and Construction Engineering at Oregon State University. He is currently serving as the Editor-in-Chief for the ASCE Journal of Surveying Engineering. He has received BS and MS degrees in Civil Engineering from the University of Utah and a Ph.D. from the University of California, San Diego. He has also worked as an Engineer in Training for West Valley City. His current areas of research include terrestrial laser scanning, remote sensing, GIS, earthquake engineering, hazard mapping, and 3D visualization. He teaches geomatics engineering courses at OSU where he has developed new, ground-breaking courses in 3D laser scanning, Digital Terrain Modeling course and Building Information Modeling.

Kevin Konynenbelt is the CEO of Solv3D, an innovation leader in 3D point cloud processing (3DPointLogic) and visualization (SiteVisit360). He has led and built high performing teams in sectors ranging from finance, software integrators, energy and manufacturing. Kevin has worked in North America, the Middle East, and Europe for major firms in oil and gas, aerospace, defence, utilities, finance/treasury, airport authorities, telecommunications, government, and agriculture. Bringing a customer first approach and extensive leadership experience he provides technical, product management, and operational focus.

Robert Radovanovic is the Manager of New Technology Ventures at McElhanney Geomatics Engineering Ltd. Previously, he was the CEO of SarPoint Engineering Ltd. until its acquisition by McElhanney in 2017. Dr. Radovanovic is heavily involved in the fields of 3D mapping and precise measurement, with an emphasis on how these technologies augment civil infrastructure projects.





Emails for upcoming seminars are sent to all ASPRS, CaGIS and GLIS members with the registration link. Just click on the clink in the email to get to the online registration for each seminar. Please note that slots for the live seminar are limited to 95 so register early to be assured you are approved. It is also important that if you register for a seminar that you do attend as there are more people interested in the live seminars than there are slots available to accommodate everyone. After the live seminars have aired, a videotape of the seminar will be posted.
