In the dynamic landscape of humanitarian response, UNOSAT's emergency mapping service celebrates its 20th anniversary, marking two decades of groundbreaking achievements in emergency mapping.

Established in 2003, UNOSAT's Emergency Mapping service offers critical satellite image analysis during humanitarian crises such as disasters, complex emergencies, and conflict situations. With an unwavering commitment to 24/7 availability throughout the year, a team of seasoned analysts ensures the prompt delivery of satellite imagery-derived maps, reports, and data tailored for direct integration into Geographic Information Systems (GIS).

Over the last two decades, the program has played a pivotal role in documenting and responding to crises worldwide. Operating to the benefit of member states and UN agencies, it left an indelible mark on the intersection of technology, humanitarian aid and human rights. 

UNOSAT's versatile missions encompass mapping for floods, earthquakes, storms, landslides, volcanoes, oil spills, chemical waste incidents, and refugee and Internally Displaced Person (IDP) camps. These endeavours stand as a testament to its commitment to delivering timely and invaluable satellite-based solutions in diverse and challenging humanitarian contexts. A mission is all the more crucial as it is often impossible to access quality information in rugged terrains.

As OCHA South Sudan, we neither have the technical capacity in-house to do satellite imagery and the needed analysis nor do we have the time. UNOSAT provides this analysis that shows the number of population, areas affected, and estimated people exposed. All this gives us an amazing immediate big picture of the real situation. Then, the intercluster coordination group undertakes an in-depth analysis to help shape the response. It means that the initial analysis feeds into the discussions of the decision makers, explained W.A. Kumudu Sanjeewa, head of communications at UNOCHA South-Sudan. For me, this is an excellent collaboration, the technical as well as the managerial level went beyond expected.

Beyond immediate crisis response, UNOSAT's Emergency Mapping Service actively contributes to building resilience within vulnerable communities. By providing accurate and timely information, the program supports long-term disaster risk reduction and preparedness initiatives, exemplifying a dedication to sustainable impact. “20 years ago, we received our images on CDs”, remembers Olivier Van Damme, Senior Specialist Officer for UNOSAT’s Strategic Planning and Coordination Section. “In the realm of humanitarian response, the prominence of our service has grown steadily; however, it coincides with an escalation in the frequency of crises. Despite our unwavering efforts, continuous innovations, and the support we have already garnered, we find ourselves in the position of requiring additional resources to sustain the current standard of excellence.”

UNOSAT enters its third decade of bringing technical excellence to the most fragile populations. The agency’s commitment to advancing technology, broadening collaborations, and contributing to global resilience remains unwavering. The program looks ahead, dedicated to its mission of creating a more prepared and resilient world through its innovative emergency mapping services. And leveraging technology to help everyone access objective, scientific, and reliable information.
