SuperGIS Experience in the Use of GIS for Census Mapping Applications


In the era of “big data”, the authorities in Taiwan rely heavily on the vast amount of data when they are making a significant decision or formulating a new policy because it’s believed to be a smarter way to meet the true need of citizens. The Directorate General of Budget, Accounting and Statistics (DGBAS) of Executive Yuan, is one of the major data providers in Taiwan. DGBAS is not only in charge of the national budget, accounting and statistics affairs, it also conducts many nationwide surveys, such as “Industry and Service Census”, “Population and Housing Census”, and “Agriculture, Forestry, Fishery and Animal Husbandry Census”. These censuses are taken every 5 to 10 years and usually cost considerable time, money, and manpower to finish the work. Despite the huge expenditure, these data are crucial for our government to understand the population and industrial structure in Taiwan. By making reference to these census data, the authorities concerned can think about how to tackle social problems, such as upgrading industries and the aging society.

In addition to developing better policies, these precious data are also useful for other applications in the academic field and the industry, or just for normal citizens to acquire the information about the current status of the society. Therefore, every time the DGBAS finish a census, it will publish its fruitful survey results and the statistical analysis reports on the official website. Also, DGBAS wants to share the big amount of data with all citizens on a better-designed webpage, so that the information inferred from the census data can be understood by more people.


In the past, the census data were often written in a fix webpage template. Though users could still see the trend of data from the statistical diagrams on the website, the layout styles were constrained by pre-designed formats and graphs. When users have interests in a piece of data and would like to explore the data in a more flexible and intuitive way, an advanced solution is needed to fulfill this goal.


Hence, if all census data can be integrated into the spatial database, these precious data can further be activated by users as they are allowed to visualize the data in more creative ways based on their own preference. Also, they will be able to explore and interpret the census data from the perspective of spatial relationships.


To realize this goal, Supergeo has helped DGBAS collate three major census data and integrated them into the geospatial database since 2016. Also, we have established a web map to display all census data by applying SuperGIS Server.


The online geographic information platform developed by Supergeo enables users to search for the census data they want, and use plentiful methods of visualization to display the results on the digital map, such as statistical table, pie charts, bar charts, radar map, choropleths, dot plots, grading symbols, statistics maps, and so on.
