Geospatial Framework



TNC Global Oceans staff, working in conjunction with TNC staff in Indonesia, continue to collect and explore relevant geospatial data to set the foundation for the social-ecological urban analysis for the coastal city of Semarang. The objective is to build a replicable analysis that incorporates social media-based flood event data with socioeconomic, ecosystem, and vulnerability information.

The goal is to show where existing habitats either reduce risk and therefore should have protections, and where frequently-inundated areas may benefit from habitat restoration and other green infrastructure projects. It could also be useful in revealing sources of community vulnerability to regular flooding events.



In collaboration with FloodTags, Peta Bencana, Wetlands International, Deltares, Esri, Microsoft, and GDPC, TNC has led the development of the geospatial framework for Resilient Coastal Cities.

The framework is designed to:

  • Incorporate crowd-source social media data on flood events
  • Build a communications campaign and user base around local flooding
  • Utilize coastal engineering design parameters from Demak (west of Semarang on the north shore of Central Java)
  • Simulate mangrove restoration scenarios
  • Build a mobile app and dashboard to integrate the information
  • Deliver the framework, analysis and app to the coalition-building process in Indonesia.
