Among Geographic Information Systems functionality is the retrieval of spatial data by using various spatial operators. The proposal of this paper is about the definition of new spatial operators that are based on projective and affine geometric invariants. Such a special category of geometric properties, despite being not widely used in previous work, reveals itself a very interesting realm for the exploration of new operators that are both powerful and easy to use from an end-user perspective.
