This is the example of Perdigões. In this image of the
early nineties, the olive trees were not yet removed, the ploughing for the
vineyards was not yet done and the spectacular areal image that revealed
Perdigões set of enclosures was not yet taken. But the ploughing could have
been avoided if this picture, available in the net, was carefully studied: part
of the two outside ditches are perfectly visible in the south side of the site,
near the road.
Of course, Google didn’t exist then and large projects
of agriculture were not submitted to impact studies.
Another example is Outeiro Alto. This site is now
preserved in an island inside a water reservoir.
But it is interesting to see, in a Google Earth image
of 2003 that vegetation defines the “flower” shape of the enclosure. A very
thin suggestion of an enclosure (now easier to interpret, after the site has
been discovered in the course of the construction of the tank), but a regular
practice of analyse this kind of images, especially when the first evidences of
prehistoric material are recorded, may be proved worthy.
And could this be a new one found this afternoon?
Possibly. We shall see.
