It is no secret that Apple has been using vehicles equipped with advanced cameras and sensors to collect geographical data to improve Apple Maps. However, the process of collecting data was known only to Apple’s team until now. Well, that changes today.
We have now come to know more about the process that the Cupertino-based tech giant uses to collect data for its Maps platform, including the vehicles and gadgets that the company uses, and protocols that Apple’s team has to follow to collect geographical data and capture images, thanks to Apple’s internal material released online by a Twitter user that goes by @YRG04E (Andrey)
While Apple started collecting data using modified versions of vans, the company now has two car models in its fleet, a white Subaru Impreza and a Lexus x450h. The white Subaru Impreza is codenamed Ulysses, while the Lexus x450h is codenamed TycheEach. The Subaru Impreza needs a driver to drive it, the Lexus x450h is a self-driving car.
The manually driven cars have a tower on the roof that have high-resolution cameras with Zeiss lenses and LiDAR scanners. The self-driving cars, on the other hand, have a horizontally-mounted camera system. These cameras feed captured images and data into a 2013 Mac Pro that resides in these vehicles. The computer processes all the data captured by these cameras in real-time.

All of these processes are controlled by a modified version of the iPad that Apple calls the EyeDrive unit. This iPad is loaded with an EyeDrive app which provides the assignments to be done and allows operators to manage the captured data. Andrey also reveals that there are two different EyeDrive apps, one for manually-driven cars and one for self-driven cars. Both apps have distinguished icons.
Each car is said to have four 4TB SSDs, which are used to store the collected geographical data. These SSDs are shipped to Apple at the end of the day to process the data further. According to Andrey, the set of four 4TB SSDs reaches its storage capacity within a week. He claims that Apple uses UPS overnight delivery service to ship replacement SSDs.
Apple directs the team to start capturing when the sun is at a 30 degrees angle and stop the process when the sun reaches 30 degrees again. If images and data are captured before or after these timings, the sun rays seem to interfere with LiDAR sensors. Apple also directs its operators to collect data in perfect weather conditions so that the images come out consistent.
At the end of the day, these cars return to a safe and undisclosed location, where operators inspect the car, save the collected data safely, and turn off all the systems. These locations are rented by a front company to maintain anonymity. All the collected data is then used to improve features in Apple Maps, including Flyover and Look Around.
Apple is said to be expanding its network of vehicles for collecting geographical data to Canada, Europe, and Japan.
Google has been collecting geographical data from far longer than Apple and therefore Google Maps has much more information than Apple Maps. Although, Apple Maps seem to have a better quality of information. Plus, Apple is ramping up its game to collect geographical data. It is to be seen who offers the best maps platform, Apple, or Google. Which one is your favourite? Apple Maps or Google Maps? Do let us know in the comments section below.
