Box 11: Data mashing
'Data mashing' is a process of re-using information. It entails merging of different types of data (e.g. mapping and transport data) to produce new products or services. 'Mash-ups' most commonly combine mapping data, such as that provided by Google, with data from another source. For instance, the website Chicagocrime combines mapping data with information from the Chicago police department to create a free, automatically updated map of crime incidents in the city.
In the same way, the innovative American retail website Zillow combines mapping data with information on local land value and house price sales to create a service that accurately estimates the value of a home at a given address.
