Post-event topographic (and urban) change detection for EM response and rebuilding
The Haiti EQ demonstrated that high-resolution topography collected following a natural disaster can be invaluable for evaluating extent of damage to building stock, determining locations for relocation camps, and tracking displaced people.
Emergency responders, relief workers, NGOs,
Web-based portal to data, Web services for data access, processing and analysis.
Existing data distribution, processing, analysis and visualization infrastructure. Post- (and hopefully pre-) event data.
1. High-resolution lidar data are collected immediately following the event, and are processed and delivered as quickly as possible
2. Pre-event data, if available are located and loaded into data system along side post-event data
3. Responders and recovery workers access data via web-based portal, perform basic change detection, hydrologic, and other analysis on hosted data.
4. Results of analysis are delivered as simple geolocated visualization products (preferably useable on a mobile platform for use in the field).
Data are online and publicly available for future use
