What is Cartographer?

Google announce the open source release of Cartographer, a real-time simultaneous localization and mapping (SLAM) library in 2D and 3D with ROS support, in October 2016. As Robotics Trends said, "Google wants to democratize the development of SLAM technology by releasing an open-source version of its Cartographer mapping library." Google is now putting it to use to map anything from hotels to museums.
