Using laser-based lidar, the Detroit-area company Ushr mapped 130,000 miles of freeway in the United States and Canada, in deep detail. That map is stored onboard the car, and updated monthly over the air to account for new construction and other road changes. The maps fix the Cadillac’s global position to within four inches, backed by onboard cameras, radar and GPS.


“As it developed the system, Cadillac hired a company called Ushr to drive every mile of limited-access highway in the US and Canada, using a lidar laser scanner to record all the lane lines, tollbooths, curves, merges, splits, and other features.

It trimmed away some useless lidar data (like roadside trees), and compressed what was left until it fit easily on a car’s computer.”


“Ushr, the Detroit-based developer of high-definition maps used in General Motors Super Cruise system is being acquired by Japan’s Dynamic Map Platform Co.”


“While other self-driving technologies have terabytes of data in the cloud that gets transferred to the car when needed, Ushr reduced 130,000 miles of high-definition maps to a 300-megabyte file that stays in the car.”


“How often we re-map all of our roads is of critical importance. Ushr’s current database covers about 200,000 miles of controlled-access highways in North America, and even so, the amount of roadway that changes in that database is between 6,000 and 8,000 miles a year, says Mr. Thibodeau.”


“Ushr Inc., a Livonia, Mich.-based provider of high-definition mapping technology and software for autonomous and semi-autonomous vehicles, raised $10 million in Series A funding.


"Cadillac Super Cruise uses Lidar maps from startup Ushr, which mapped every mile of interstate highway in the US and Canada by driving it. That means a Cadillac with Super Cruise will know exactly what it will encounter—every curve, exit, and lane merge."


"General Motors is also announcing today that the SuperCruise system will start hitting other GM brands — such as Chevrolet, GMC, and Buick —  after 2020. 

GM employed Ushr, Inc, a startup in GM Venture’s portfolio, to map 160,000 miles of expressways in the U.S. and Canada. The car company then used Super Cruise-equipped vehicles to test each mile."
