Plans Reliefs – Louis XIV

In Europe the period of glory of 3-dimensional modelling came with the reign of Louis XIV (1661 to 1715), the Sun King, who ordered the manufacturing of 140 scaled raised relief models depicting cities that had recently been incorporated into the Kingdom of France, so that he could see for himself the bastioned fortifications proposed by his military engineers. The relief models were instruments of exclusive knowledge management.

The gallery in Paris where these were stored, was kept secret from the eyes of the public. Like a hidden vault, accessible only to a restricted elite, it contained spatially defined, visualized knowledge enshrining the entire power of the Kingdom. Interestingly enough, this is a first example of large-scale geo-spatial information storage and management.

Because of their strategic function, engineers manufacturing raised relief models took great care in providing an exact representation of the settlements in relation to their surrounding landscape.

This was extremely important for military engineers who would want to know whether or not a city could be targeted from a particular hill, in order to take the necessary protective measures. This is why despite its strictly utilitarian function, raised relief models of that historic period paid such minute attention to the landscape around cities. After Louis XIV, other relief models at a scale 1:600 were manufactured both for defensive engineering and for commemorative purposes.
