How might digi-hogs help our hedgehogs?

Cambridge University academics are hoping to figure out how to save our hedgehogs.

Researchers are using a hi-tech approach to stop their decline by mapping habitats.

Satellite images, Artificial Intelligence and "digi-hogs" are all involved.

Anil Madhavapeddy is a professor of Planetary Computing and tells Louise Hulland how he 'accidently' got involved in the project.
