Abstract
The recent damages caused by floods have called for better preparation from vulnerable communities. New data sources like in-situ sensors and social media have opened different perspectives for supporting data collection, and then improving decision-making of the emergency agencies. Therefore, this paper presents a geographical analysis of the relationship between authoritative data and georeferenced social media messages with the aim of understanding their contributions to decision-making in case of floods. The results showed a straight relationship between georeferenced social media messages and authoritative data. Furthermore, it was revealed that these messages are useful to provide information about the situation at the affected area.
