The Future of Spatial Data Infrastructures
نویسنده
چکیده
This paper addresses two central questions relating to the future of spatial data infrastructures (SDIs) Where have we got to now? Where should go from here? The answers to the first question are to be found in a review of the main milestones of SDI development over the last two decades and a comparative evaluation of SDI experiences in different parts of the world which constitutes the first main section of the paper. The answers to the second question are inevitably more speculative in nature. With this in mind the second main section examines some emerging trends and explores some of the main strengths and weaknesses of current SDI practices in relation to the perceived opportunities and threats that are likely to emerge in the foreseeable future. The paper concludes with a discussion of four key issues that are likely to play a vital role in determining the future success of SDIs.

An information-starved society is limited in its social and economic development. It follows that a society which is not geographically aware or “spatially enabled” is deprived of the ability to effectively plan. The need for accurate spatial information for planning and monitoring of present activities and ensuring sustainable future development has led to the concept and development of spatia...
