Many business organizations utilizeMany business organizations utilize GIS GIS as a means of capturing, managing as a means of capturing, managingand delivering spatial data. Usingand delivering spatial data. Using GIS GIS as an as an ‘‘information kioskinformation kiosk’’ has in some has in someinstances caused it to be perceived as a peripheral service function, separateinstances caused it to be perceived as a peripheral service function, separatefrom the core technical work process of the company.from the core technical work process of the company.
