New data sources for real estate

The exponential growth of recorded data is one of the most striking features of technological change over recent years.  Not only did the volume of global data nearly double between 2015 and 2018 to 33 zettabytes (one zettabyte corresponds to 1,000 bn terabytes), but it is also projected to increase to 175 zettabytes by 2025, according a study by the International Data Corporation (IDC).
