[HCG27-P02] Utilization of Location Information Concerning Disaster Management and Infectious Disease Control

*Kayoko Yamamoto1 (1.The University of Eectro-Communications)

Keywords:Location Information, Disaster Management Control, Infectious Disease Control

Due to the spread of mobile devices with GPS (global positioning system) functions such as smartphones, tablets, and PCs, location data is not only used for navigation but is also used to obtain various information related to the location data. For example, traffic estimations on commuter routes, search results for nearby facilities, and detailed information within a small area can be obtained. The background for this is that with the realization of a cloud computing society which was enabled by the advancement of information technology in many countries and regions, the environment in which a large amount of various information can be easily obtained “whenever”, “wherever”, and by “whoever” using some form of information system was improved. In addition, location data that was mainly used on mobile devices is now also used on PCs. This is due to the advancement of the technology that estimates the current location from the IP address assigned to a user’s PC.
On the other hand, in recent years, natural disaster management have become the most important topic as the occurrence of meteorological disasters such as typhoons, torrential rain, and droughts in addition to earthquakes and volcanic eruptions have increased worldwide. Additionally, due to the global spread of COVID-19, there has been a total of over 150 million infected people as of May 1st, 2021. While there are regional differences, the number of infected people in Japan has also remained high and the situation has reached a catastrophic level requiring long-term measures.
As mentioned above, the range of location data utilization is expanding and it is expected to be further utilized for various purposes in the future. It has also been used in disaster measures for a wide range of purposes from before a disaster as well as in the recovery/reconstruction stages. Location data has also been used in many aspects to control infectious diseases. Although location data can be expected to be used for numerous purposes, there are many issues that remain related to utilization that should be considered by society as a whole. In this paper, location data for disaster management and infectious disease control will be covered with the purpose of organizing various aspects of utilization to discuss the relating issues.
Location data for disaster countermeasures has been actively used since the Great East Japan Earthquake and Web-GIS has played a major role in this as it enables the consolidation of various information on digital maps. Additionally, with the spread of social media to many countries/regions worldwide along with the advancement of the cloud computing society, it has become evident that the efficient utilization of location data such as the consolidation of posts with location data from social media on a Web-GIS digital map is progressing.
After the global spread of COVID-19 in recent times, location data has also been utilized for infectious disease control and digital infection tracking has rapidly expanded. However, there are differences in the utilization of location data in each country which reflects the unique historical background in addition to the social and economic conditions of each country. Regarding this point, the start of discussions on future regulations is desirable to prevent digital surveillance in each country.
As mentioned at the start of this paper, with the expansion of the utilization range of location data, its future utilization for further diverse purposes has been anticipated. Although location data can be expected to be used in many ways, there are many issues concerning utilization that still remain as explained in Section 4 and it is necessary to take this into consideration when utilizing such data.
