Selection of our work

FloodTags helps organisations work with user generated content in their water and development projects. Hereunder a selection of our work:

Online dashboard to connect to the API

Global Flood MonitorFloodTags developed a Dashboard to access FloodTags’ data easily on the web (also for mobile devices). Via the Dashboard you can online monitor new developments related to floods by searching through the online media content. The Dashboard alerts you about new floods happening (in many countries Twitter is the first platform to hold information on new flood events) and you are able to review new information about those flood events (situational awareness) in real-time.

Please note that all data and functions that you will find in the Dashboard, are also accessible from the API. There you can find the full suite of Floodtags' functions, and connect to them from within your already existing applications or Dashboards (if you have them). Read more.

Flood Observations for Red Cross Philippines

Citizens and comFlood_damage_in_Manila,_Philippines_2012._Photo-_AusAID_(10695722693)munities in Philippines are affected by floods each year. For 2014 alone, the Philipines Red Cross registered 21 floods in 80 different areas in their country. To respond to the floods effectively, disaster managers need to know how the people are affected. What FloodTags and partners will do is collect Twitter data and filter out the most relevant flood observations. Next, we combine it with various relevant (water) information so that we get a clear overview of what is happening on-the-ground during a flood. The results will be used as addition to the volunteer reporting system that is already in place, so that response activities of the Philippine Red Cross can be planned even better. The project is winner of the prestigious Challenge Fund of the Worldbank. Partners in the project are the Red Cross Climate Centre (RCCC), Deltares, VU University Amsterdam and Radboud University Nijmegen.

Global Flood Monitor on the basis of Twitter

Twitter contains information about new flood events, as observed andKaldari_Nashville_flood_08 reported by citizens, news agencies and otherorganisations. In this project, FloodTags and Deltares developed a flood detection on the basis of Twitter and connected it to an event server at the ID-lab. As a result, disaster management agencies obtain timing and location of new floods as observed from Twitter and take appropriate measures (or obtain additional information from satellite products). To obtain a first global flood overview using Twitter, we were looking for a ‘certain flood’ approach. Meaning that we aimed to minimise false positives while allowing for a fair amount of false negatives... Read more.

Dengue and Diarrhea forecast for Indonesia

c229beaf-7554-47f9-8886-d7519f76aed2In Indonesia there is little reliable data on waterborne diseases such as dengue and diarrhea. In this project we developed a relation to forecast new outbreaks on the basis of reported floods. For the research we used three datasets: Flood tweets, health tweets and field data from hospitals. After validation, we implemented the resulting forecast in FloodTags' data service so that it can be used by the Ministry of Health of Indonesia to support health measures. The project was part of the "Data Innovation Grant" organised by UN Global Pulse. FloodTags and partners Radboud University and Universitas Bandung (UNPAD) are the winners of this contest together with three other innovative data projects for Indonesia.

Local newspapers show where Uganda was flooded in the past

Capture2Most extreme weather events are recorded in local newspapers. However it is labor intensive to review all the archives. FloodTags supported RCRCCC by downloading and analysing newspaper-aggregated information about historic floods events. The result is a historical flood map with dates of flood occurrences and links to the relevant news articles. This can now be used by RCRCCC to prepare for future floods through Finance Based Forecasting in Uganda. Read more.

Real-time Flood Maps for Jakarta

FloodTajakarta roundaboutgs and Deltares developed an automated procedure to use the thousands of observations generated by the social media for real-time flood mapping. By applying statistics and using hydrodynamic corrected Digital Elevation Maps, they piloted the method for Jakarta where with 75% accuracy they could simulate flood extent. The real-time flood-extent maps provided a good comparison with ground-truth photographs in most neighbourhoods in Jakarta. Read more.

Tool to build "Flood Classifiers"

Relevancer2How do you know which text messages are relevant and which are not? The Centre of Language Studies of Radboud University and FloodTags developed a tool that classifies text messages using a K-means algorithm. The tool is named "Relevancer". On the basis of initial user input (annotating clusters of content in several rounds of user input), Relevancer estimates the relevance of the text messages and classifies the observations on the basis of the words and language that is used.

Develop with us

FloodTags works together with a growing research community that develops open software for specific tasks within data analysis for water management. If you would like to participate in the research or otherwise be connected to its results, please contact us!
