And what that means, according to Google, is that Maps developers will be able to produce more detailed maps while producing better code.
In addition, Maps developers using the new feature will be able to add more information to their maps for users, she wrote. "And what's more, most places have attributes beyond just location: stores have opening times, rivers have current speed, and each Girl Guide troop has cookie selling turf. The Data layer allows you to represent all attributes in GeoJSON right on the map and make decisions about what data to display more easily."
The new code feature also means that developers can create a styling function with specific attributes and that as the data or rules are updated, "the styling will automatically be applied to every feature," wrote Kovnats. "This beats having to manually update each feature or rule as more information is added to the map."
