Using the satellite images of the town’s urban centre and outlying urbanisations and rural zones, officials have identified 5,627 structures that are not reflected in the property register. The majority of the unregistered buildings, 69 per cent of which existed prior to 2002, are in the countryside and the El Rodeo, Cortijo Benítez, Miravalle and Las Delicias districts.
Comparing images taken in 2002 and 2006, officials discovered 2.676 land-use changes.
