Spain's aerial photography comparator in different years


With the photo comparison tool you can view two aerial images of the same specific geographic area at the same time. Flights are performed without a chronological or spatial order, so you can find places where there is no photographines in a particular year. WMS services offered by various state and regional institutions have been used to achieve the interactive map.
