So, how do we build a high quality map and keep it fresh? At the core of the process is our innovative collection technologies blended with a team of local experts.
Using their intimate knowledge of local road networks and surrounding areas, these experts, who drive millions of roadways each year, use specially equipped vehicles to collect and verify location data.
Depending on local conditions, product requirements and a variety of other factors, the local drivers use distinct collection technology, ranging from highly mobile pedestrian collection tools to the sophisticated NAVTEQ True technology.
NAVTEQ True is actually composed of four unique technologies:
- 360° LIDAR: Rotating lasers capture 1.3 million 3D digital data points every second, which generates a virtual 3D model of the world around the vehicle.
- Position Sensors: GPS and military grade Inertial Measurement Unit (IMU) sensors measure the vehicle’s speed, orientation and even gravitational forces to provide highly precise location references to every point within the virtual 3D model.
- Panoramic Cameras: These cameras layer in a 360° images synchronized to the 3D LIDAR points—giving us the most true to life representation of the world
- High Resolution Multi-View Cameras: High-resolution images give us the opportunity to increase automation so we can more quickly bring advanced location content to more people.
Worldwide, NAVTEQ True technology is gathering an immense amount of data.
- Press the Search button on your Nokia Lumia and then tap Vision
- Scan the barcode
- Tap on the link when it appears on the screen
- Install the application from the Windows Phone Marketplace
For instance, in one single day, we might collect 12 million signage images, two million panoramic images, a trillion LIDAR points, and 65 million million (65,000,000,000,000!) colour pixels. We’re not just taking pictures of the world; we’re creating a new data model of the world.
With this level of high quality data, NAVTEQ True technology is capturing real world dimension, fueling more realistic and interactive experiences. With data collected by NAVTEQ True, you can explore the world more easily and in a whole new way – you can instantly see all the best places to eat and things to do and see it right on your phone’s camera display. It’s like having x-ray vision, revealing the hidden spots you might otherwise miss.
