Using vedute to source geospatial information: data flowline and accuracies

An introduction is given to the methods by which spatial data integration exercises can use information from a wide range of sources. The nature of landscape paintings, and their possible use as such a source, is discussed. The measurement of planimetric coordinates from vedute paintings, using standard projective geometry tools, is described. Tests are undertaken to determine whether such paintings, which can present true visual perspective, allow for spatial fidelity to be ‘re-engineered’.
