Dozens of startups are working on lidar, a type of laser sensor that many experts see as essential for fully self-driving cars. In my view, one of the most interesting companies is called Ouster. I first wrote about Ouster back in May, when I explained how it was bucking an industry trend toward fixed “solid state” lidar in favor of the spinning design pioneered by industry leader Velodyne.

Because Ouster’s lidar looks so much like Velodyne’s on the outside, I assumed that it looked similar inside, too. But in a recent interview with Ars Technica, Ouster CEO and co-founder Angus Pacala told me that Ouster’s lidar is actually radically different inside.

Patent filings show that Velodyne’s venerable 64-laser lidar has a stack of circuit boards, each connected to an individually packaged laser. By contrast, if you crack open the case of Ouster’s 64-laser unit, you’ll find that all of its 64 laser beams emanate from an integrated circuit not much bigger than a grain of rice.

When researchers surveyed the ruins of a Purépecha Empire city in Mexico the old-fashioned way a decade ago, it took them two seasons to explore two square kilometres. Good thing they decided to use LiDAR, because the city called Angamuco turned out bigger than they previously thought. LiDAR gave the researchers the power to see underneath the lava that covers Angamuco. Thanks to the laser technology, they now know that the city occupied 26 square kilometers of land instead of 13 square kilometers. Colorado State University archaeologist Chris Fisher is presenting that finding and all the latest info on his team’s study at the ongoing American Association for the Advancement of Science conference in Austin.

“That is a huge area with a lot of people and a lot of architectural foundations that are represented,” Fisher told The Guardian. According to their estimates, the city had around 1,500 structures per square kilometer of land. “If you do the maths,” he added, “all of a sudden you are talking about 40,000 building foundations up there, which is [about] the same number of building foundations that are on the island of Manhattan.” Further, LiDAR also led to the discovery that the city had an unusual layout, with big structures like pyramids and open plazas situated around the edges rather than in the center.

The Purépecha people existed at the same time as the Aztecs. While they are nowhere near as popular as their rivals, they were still a major civilization and had an imperial capital called Tzintzuntzan in western Mexico. Based on the team’s LiDAR scans, though, Angamuco is even bigger Tzintzuntzan. It likely wasn’t as densely populated, but Fisher said it’s now the biggest city in western Mexico during that period that we know of.

The use of LiDAR (or light detection and ranging) is becoming more and more common in archaeology, since it allows researchers to scan large areas of land in mere minutes. It creates a 3D map of the landscape by firing a rapid succession of laser pulses at the ground from a plane. Those pulses can penetrate foliage and soil, enabling scientists to see what’s underneath them all without having to cut down a single tree. Earlier this month, for instance, a research foundation revealed that it found a vast Mayan megalopolis in the Guatemalan forest using LiDAR. They discovered 60,000 previously unknown structures hidden underneath centuries of growth, and they might find even more when they scan Guatemala’s lowlands in the future.

A vast Mayan megalopolis apparently lies hidden underneath all the trees, creepers and centuries of growth and soil in the Guatemalan forest — and we might never have found it if not for the wonders of laser technology. The PACUNAM Foundation, which champions the use of scientific research to preserve cultural heritage, has scanned the jungles in the country using Light Detection and Ranging (LiDAR) technology and found an interconnected network of ancient cities. They discovered 60,000 previously unknown structures without having to cut down a single plant, and that discovery changes many things we thought we knew about the ancient civilization.

The sheer size of the megalopolis suggests that Mayan populations were bigger than we thought. Previous estimates put the Mayan people’s population at around 5 million, but now it’s possible that there were 10 to 15 million of them. The fact that the team discovered houses, pyramids, palaces and elevated highways even though Mayans didn’t use wheels or relied on beasts on burden indicates that they had an organized workforce.

Since the cities in the hidden megalopolis were connected by wide causeways, the Mayans likely interacted regularly and might’ve had established trade routes. Further, all the ramparts and fortresses found in the ruins show that “warfare,” as team member and archaeologist Thomas Garrison explained, “wasn’t only happening toward the end of the civilization.”

While we mostly talk about LiDAR as a system that helps self-driving cars and robots “see” their environments, scientists have also been using it to survey the environment without disturbing it. That’s why it’s the perfect tool for PACUNAM’s scientists — aside from the fact that physically looking for the ruins would’ve taken forever, Guatemala is already losing 10 percent of its forests every year to agriculture and human settlement. In fact, we’ll probably hear more discoveries in the future, since this is only the initiative’s first phase: the organization plans to use LiDAR to map over 5,000 square miles of Guatemala’s lowlands in the future.

A recent aerial survey revealed thousands of ancient Maya structures previously hidden beneath the dense Guatemalan jungle, including houses, irrigation canals, fortifications, and even a pyramid. More importantly, though, the survey of 2000 square kilometers of northeastern Guatemala provides a bird’s-eye view of the landscape of ancient Maya cities, farms, and highways. That big picture view of the Maya is letting archaeologists ask bigger questions about this still-enigmatic civilization.

A sense of mystery still surrounds the Maya, mostly because so much of their once powerful and sophisticated society now lies hidden beneath thick tropical foliage. In recent years, archaeologists have started using lasers to peer beneath the thick canopy of leaves and map the ancient Maya landscape from above. They’re using a technology called “light detection and ranging,” or LiDAR, which maps the height of features on the ground by measuring how long it takes infrared light beamed down from a plane to bounce off those structures and return to the instrument.

Using a plane lets surveyors cover a lot of ground in a short time, and one recent survey covered the largest area so far. The results hint that Maya civilization may have been more extensive and more densely populated than archaeologists realized. The survey, funded by the nonprofit Pacunam foundation, covered 2000 square kilometers of northeastern Guatemala in 2016. Archaeologists have been poring over the data since early 2017, and they say they’ve discovered over 60,000 new structures, from irrigation canals and highways to fortresses and pyramids.

On November 3, 2007, six vehicles made history by successfully navigating a simulated urban environment—and complying with California traffic laws—without a driver behind the wheel. Five of the six were sporting a revolutionary new type of lidar sensor that had recently been introduced by an audio equipment maker called Velodyne.

A decade later, Velodyne’s lidar continues to be a crucial technology for self-driving cars. Lidar costs are coming down but are still fairly expensive. Velodyne and a swarm of startups are trying to change that.

In this article, we’ll take a deep dive into lidar technology. We’ll explain how the technology works and the challenges technologists face as they try to build lidar sensors that meet the demanding requirements for commercial self-driving cars.
