#26 - Raul Bravo

In this episode, Austin catches up with Raul Bravo, a prolific inventor holding more than 70 international patent families. As president and founder of Outsight, Raul explains how his firm's technologies transform streams of lidar data into real-time 3D spatial intelligence. The conversation delves into the analytical capabilities of dynamic 3D databases and explores the technical challenges of orchestrating thousands of laser scanners into a cohesive sensing system.

In this episode, Mach9's co-founder and CEO, Alex Baikovitz, talks enthusiastically about the company's mission to improve geospatial workflows for generating information from point clouds, making heavy but considered use of AI, plus innovations from the world of robotics. His flagship product, Digital Surveyor, outputs the derived features to familiar CAD and GIS software suites and can be deployed from a web browser. Alex claims speed improvements of 5x compared to more traditional software approaches – and much more dramatic numbers in certain circumstances. The company emerged from Carnegie Mellon University in Pittsburgh, but is now located in downtown San Francisco, where the availability of a top-quality workforce and closeness to other well-known geospatial firms have proved beneficial.

Dr. Florent Poux is an award-winning researcher and adjunct professor in 3D Data Science at the University of Liège. Based in Toulouse, France, Florent operates the 3D Geodata Academy, a training resource dedicated to building innovations with 3D technology. In this episode, Austin gathers Dr. Poux's thoughts on how to employ novel data processing pipelines to extract value from 3D data. They also discuss his recently published book, 3D Data Science with Python, which seeks to help readers understand modern algorithms and spatial AI models, with a focus on hands-on learning and automation.

Dr. Helen Fricker is a Professor of Geophysics at the Scripps Institution of Oceanography at UC San Diego, one of the world's most important centers for global earth science research and education. Prior to her current role, Dr. Fricker was a science team member for NASA's Ice, Cloud, and Land Elevation Satellite (ICESat); she is currently the science team lead for ICESat-2, and Principle Investigator (PI) for NASA's Earth Dynamics Geodetic Explorer (EDGE) mission. In this episode, we pick Helen's brain about spaceborne lidar altimetry missions, some of the amazing science and research projects they support, and what's over the horizon from a development perspective.

Angus Pacala is CEO and co-founder of Ouster, a major lidar supplier based in San Francisco. The company made headlines in 2023 when it merged with arch-competitor Velodyne. Speaking from the company's offices in Edinburgh, Scotland (home of Sense Photonics, an Ouster acquisition in 2021), Angus addresses the company's technical developments and the status of its forthcoming L4 and Chronos solid-state components and their likely effect on the product portfolio. He explains how the company addresses the four verticals into which it has divided the market and where UAV-lidar fits in. Ouster's software portfolio is covered too. 

Dr. John Adler is a geographer and remote sensing professional with a diverse career in academia, government, and ecological research. He serves as the Lead Airborne Sensor Operator for the National Ecological Observatory Network (NEON) where he conducts airborne surveys across the nation during periods of peak vegetation greenness, contributing to large-scale ecological data collection efforts. In this episode, Austin chats with John about the ins-and-outs of collecting airborne lidar data in concert with RGB + hyperspectral sensors over NEON sites from Alaska to Puerto Rico. They close with a discussion of what the future may hold for NEON data collection and upload. 

In this episode, Stewart speaks with James Rush, Lidar Subject Matter Expert, Allen & Company, about his employer and his personal journey into lidar management. Allen & Company has roots in conventional land surveying, but its offerings today include extensive services in laser scanning of buildings, producing deliverables such as BIMs and digital twins. To this end, it has a subsidiary, Allen3D. James discusses some of the projects on which Allen is working and examines how the specifications are reached in discussion with clients, paying appropriate attention to published standards. He also describes an initiative at Tucker Ranch, near the company's headquarters in Winter Garden, Florida, in which he arranged for 17 collections of lidar point clouds of a small area, to provide a most unusual reference data set for many purposes.

Dr. Ralph Dubayah is a Distinguished Professor of Geographical Sciences at the University of Maryland, College Park. He is the Principal Investigator for NASA's Global Ecosystems Dynamics Investigation Lidar (GEDI) – a full waveform lidar onboard the International Space Station (ISS). In this episode we hear from Dr. Dubayah about the ins and outs of GEDI as well as an upcoming spaceborne lidar mission that's under preparation. We wrap up with a discussion of Dr. Dubayah's dream for airborne laser scanning (ALS) from space!

Josh Novac, Associate Vice President, and Program Manager in the Geospatial, Mapping, and Survey department at Dewberry, talks about how he came to enter the geospatial profession. He discusses the satisfaction and enthusiasm that his 18 years with Dewberry have engendered and explains how the family-owned nature of the business brings special advantages in terms of serving clients. Josh talks about Dewberry's decision to acquire airborne topobathymetric lidar systems and describes some of the projects that the company is currently tackling. On a more personal note, he talks about his friend and mentor, Dave Maune, whose autobiography, 25¢ Piano Lessons, was published at the end of 2024.

Philippe Simard is CEO of SimActive, the Montreal-based supplier of photogrammetric software, which he founded in 2003 with his brother, Louis, who is CTO. We explore how the company began with a successful Canadian defense procurement and has focused consistently on both ease of use and speed. SimActive's flagship Correlator3D product has evolved over 22 years and supports imagery acquired by UAVs, aircraft and satellites, with pricing dependent on image size. It is installed in over 100 countries, indicating the company's steady growth. The brothers' college degrees are in computer vision, so the podcast touches on this approach to photogrammetry as opposed to the classical one taught in geomatics programs over the years.
