Katie Prescott revisits the efforts of the Zanzibar government to chart its territory by flying drones across the African spice island.

A year ago she met planning minister Mohammed Juma, the brains behind this ambitious project that aims to clarify land property rights, provide information to local residents about the location of services and amenities, and help the government plan everything from flood management to urban redevelopment.

Katie catches up with Edward Anderson of the World Bank, who headed up the drone mapping project, to find out how the data they have gathered is now being crunched by artificial intelligence algorithms, and being made available to the public.
