Project goals:
- Верифікація даних міських органів влади про понесені збитки.
- Картографування та геопросторовий аналіз руйнувань на основі супутникових знімків MAXAR.
- Розрахунок збитків у розрізі секторів та первинна оцінка потреб у відновленні.
- Формування доказової бази для міжнародної підтримки та прийняття рішень щодо відбудови.
About the project:
ToP has successfully implemented the project Damage assessment for Mykolayiv on verifying the information collected by authorities on damages sustained by the city, calculating the damages and providing a basis for most critical emergency relief aid and post-war recovery support. The project was conducted with the help of the European Union Anti-Corruption Initiative (EUACI), implemented by the Danish Ministry of Foreign Affairs of Denmark (DMFA), launched in October 2022 and completed in June 2023.
The project was designed to verify information collected by city authorities using recent satellite imagery from MAXAR, map and compare geospatial data on damages, calculate the amount of damages by different sectors and provide initial estimates of reconstruction needs.
The project team selected 3 high-quality (50 cm per pixel resolution and low clowd mask) images from the commercial MAXAR satellite imagery, combining them to receive blended image of the 100% of the city territory, cutting and replacing pieces covered by clouds, smoke or other visual defects. A proprietary AI model was used with a twofold goal: a) preliminary object detection - attempt to automatically find polygons corresponding to buildings, and b) preliminary damage detection - attempt to automatically find polygons that may have characteristics that correspond to damage pattern. Further, the received data has been used to determine damaged buildings (under the methodology developed by International Working Group on Satellite-based Emergency Mapping) and conduct the evaluation of damages on a per-sector basis using the damaged.in.ua key methodology principles and approaches to calculations.
The results of the project have established damage evaluation to Mykolaiv’s infrastructure amounted to €852m, including €220m of damages that can be independently verified using satellite image. The project also allowed independently to confirm visually from 30% to 90% of destruction. The project has showcased the recovery needs assessment for the city - urgent needs in 6 key sectors (power supply, water supply, heating, healthcare, housing and public safety) and a need for long-term recovery in infrastructure, green transition, urban planning, transport, maritime sector, business development and investment attraction, youth, education and culture and good governance.
The results of the analysis are an important evidence of Russia’s aggression and the scale of destruction as well provide a basis for providing most critical emergency relief aid and post-war recovery support.
