Abstract

One objective of FIG Commission 3 focuses on promoting the use of Spatial Infrastructure Management (SIM)-tools at different administrative levels for decision makers and citizens to support the goals of participatory democracy. In this context FIG Commission 3 has set up the Working Group WG3.2 Spatial Data Infrastructures in Mega cities, which aims at identifying relevant spatial tools to support development and use of spatial data infrastructure (SDI) by city authorities in the world’s largest cities. The strategy of the work program emphasizes key problems of mega cities by reviewing SDI developments in existing mega cities, documenting case studies, including lessons learned about solutions for problems and should finally lead to a toolkit for use of best practises in SDI for managing mega cities. To complement the results of direct correspondence with administrations of mega cities one important part of this project concentrates on a background research of existing sources about overall use of SDI in mega cities. The objective of this paper is to discuss the results of an internet search concerning the use of Spatial Information Technology in the world’s currently existing mega cities. The search starts from a nationwide view on the execution and the progression status of SDI’s in the home countries of mega cities and zooms in to the specific aspects of spatial data management in the metropolitan areas of special interest. As a result we come to the conclusion, that current SDI development in mega cities covers the whole range from first stage conceptual ideas up to an almost complete operational SDI availability.
