[IEEE IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium - Yokohama, Japan (2019.7.28-2019.8.2)] IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium - A Cloud-Enabled Geospatial Big Data Platform for Disaster Information Services

摘要： Geospatial technologies have been widely used to support decision making in natural disaster responses. There have been various efforts from multiple disasters to use geospatial information and models for disaster preparation, response, and resilience. These separated efforts can be shared and re-used across various sectors using a sustained platform. This paper presents how a platform layered on big data and cloud computing technologies can help achieve this goal. The big data platform enables the accumulation of disaster data, models, services, and applications in spatial information infrastructures (SDI), and improves the capabilities of SDI in supporting disaster risk reduction.
