GIS technology is frequently used to examine spatial changes in social and economic development in a geographic region over time. Focusing on social sciences and humanities, the GIS Center, Academia Sinica, Taiwan is responsible for undertaking basic GIS-related research, building cross-domain integration with spatiotemporal data, and creating application environment for analysis and map metaphor.
Taiwan population statistics contains all the census statistics from Japanese colonial era to the present. However, the traditional digital data were only presented the information with tables or records and it is difficult for the government departments and the public to access the temporal and spatial distribution of demographic data across Taiwan’s districts.
To fulfill the needs of research applications, the GIS Center, Academia Sinica developed a GIS system statistical graphics which performs statistical data integration, map display, and management functions to conduct diverse scientific research such as Health Care and Environment Change, Socio-economic conditions, Historical Population, etc.
In addition to achieving seamless spatial data integration, the GIS platform helps update and manage the Taiwan’s historically demographical data with the Socio-economic indicator data, allowing users to easily find the hidden information of spatial distribution. Furthermore, the portal website offers URL of map websites in Statistical GIS that enables users to easily utilize website functions to carry out GIS applications.
In the project, Microsoft Windows Server 2008 R2 was used to build statistical data table and fill Metadata into the database. SuperGIS Server allows to publish common-used Taiwan map as map services, to integrate statistics, and to display the results on map website with layering tinting. The map website provides users with statistics querying and georeferencing functions to quickly receive needed historical data.
Serving as the powerful gateway, the GIS platform allows users to query Taiwan’s population research for academic research and general educational use. The GIS system also added interactive functions to enhance operational efficiency of the system and respond to the growing system demand. As a result, users are able to accurately identify relation between statistics data and spatial distribution through spatiotemporal visualization.
