Saving Rapid Urbanizing Cities using the FOSS4G Based Spatial Analysis for Urban Development

Early stages of urban developments such as housing construction, new town development and urban regeneration are performed through the spatial analysis using the topographic map, cadastral map, zoning map and other various kind of thematic maps for the proposed site analysis, feasibility analysis and evaluation of urban development alternatives. For these analyses, urban developers traditionally have used commercial software like ArcGIS to analyze these kinds of projects. And giant Korean public urban developer like Korea land and Housing Corporation (LH) has support these projects based on the in-house enterprise GIS system. But developing countries facing rapid urbanization near the peripheral areas of metropolitan region cannot handle such problems only using the commercial software. They need knowledge and experience about the urban development rather than complicated software based analysis techniques or large investments on the enterprise GIS system. In this sense, FOSS4G (Free Open Source Software for Geospatial) are very useful tools in that they are easy to learn, use and also relatively cheap to maintain. LH has accumulated a lot of urban development cases and wants to store this knowledge to FOSS4G based spatial analysis as a rule base. By doing so, it can manage the fast growing cities sustainable. In this presentation, we will show some conceived urban development project faced by the rapid urbanizing cities and suggest FOSS4G based spatial analysis method using the FOSS4G like QGIS plug-in.

A Cross National Comparison on the Awareness of Adopting FOSS4G to NSDI in Developing Countries

Spatial data infrastructure (SDI) plays an important role in the sharing and exchange of spatial information of the country, in this way, it has also played a major role in the development of the country's economy and society. In recent years, FOSS4G (Free Open Source Software for Geospatial) provides functionalities that are not inferior to commercial software, which lead to the diffusion of that software to the public and private sectors. Developing countries which have poor information infrastructures, there are increasing discussions about the adoption of FOSS4G to their national spatial data infrastructure (NSDI) in order to utilize the benefits of the foundation. As the benefits of FOSS4G adoption, it has suggested the low introduction cost and interoperability of software that does not depend on the specific software. But there are differences on the pros and cons of FOSS4G adoption to their NSDI because each country has their own economic and technological development stages and cultural and institutional differences. In this research, we will develop the framework to compare and evaluate the relationships between indicators on the developing countries' economic, technological development and factors in the introduction of FOSS4Gs to their NSDI and conduct a survey on the developing countries’ FOSS4G adoption to their NSDI with the help of UN GGIM(United Nations Global Geospatial Information Management) and KOICA. Thus, by comparing and evaluating each country's FOSS4G adoption to NSDI according to their countries' economic and technological development stage, we will identify the awareness of the adoption and propose a deployment strategy for overcoming the disadvantages when developing countries consider the introduction of FOSS4G to their NSDI.
