New Digital Map to Track Racial Diversity in US
Scientists in the US have created the most detailed digital map to track the changing racial diversity of every neighbourhood in the country.
Researchers from University of Cincinnati (UC) in the US applied NASA map making techniques to 20 years of data collected by the US Census Bureau to build one of the most detailed racial-diversity maps ever created.
They take advantage of NASA land-cover grids made up of 30-square-metre blocks. Using this grid system, they can more precisely group people where they actually live by recognising lakes, parks, factories and otherwise uninhabitable areas.
Researchers combined land-cover mapping techniques with cumbersome volumes of federal data collected every 10 years in the census.
The zoomable map shows at a glance how the racial compositi...
