Explanation:

Alphabet’s Sidewalk Labs, based in New York City, is collaborating with the Canadian government on the high-tech project, slated for Toronto’s industrial waterfront.
Statement 1: “Sensing city” involves integrating a network of digital sensors into the physical infrastructure of the city as it is rebuilt.
This network can generate data that will benefit not only Christchurch, but also have positive influence on the future of cities everywhere.
In the vision of the sensing city, sensors will gather data to monitor everything from noise levels to water use, in real time and at a very granular level.
The resulting data can then be integrated with other key city attributes, like traffic flow, air qualityand water pollution. A key success factor is that the data must be accessible – in an “open” data store – where it can be tapped into by city officials and citizens alike.

Statement 2: The plan calls for all vehicles to be autonomous and shared. Robots will roam underground doing menial chores like delivering the mail. Sidewalk Labs says it will open access to the software and systems it’s creating so other companies can build services on top of them, much as people build apps for mobile phones.
Here is a marriage of emerging technology – big data, the Internet of Things, generally affordable sensors and pervasive connectivity – coming together for the greater good.
