    Object-oriented concepts for software development and conceptual modelling in GIS and surveying
    Hesse, Walter ; Hazelton, William ; Williamson, Ian P. ( 1993)
    Recent years have seen a growing research interest amongst Information Technology professionals for Object Oriented Programming Systems (OOPS) and Object Oriented Geographic Information Systems (OOGIS). The nature of this research for the 'classical' surveyor demands a move away from the 'comfort zone' of Surveying Techniques, Mapping and LIS/GIS into the more fundamental areas of Computing Science. This move is essential for a better understanding of the necessary data modelling and general object-oriented concepts for Information Systems in general, and LIS/GIS more specifically. The aim of this paper is to give an overview of this relatively new and specialised field for the Surveying professional interested in GIS issues.
