Show moreSince 1980, millions of people have been harmed by natural disasters that have cost communities across the world over three trillion dollars. After a natural disaster has occurred, the creation of maps that identify the damage to buildings and infrastructure is imperative. Currently, many organizations perform this task manually, using pre- and post-disaster images and well-trained professionals to determine the degree and extent of damage. This manual task can take days to complete. I propose to do this task automatically using post-disaster satellite imagery. I use a pre-trained neural network, SegNet, and replaced its last layer with a simple damage classification scheme. This final layer of the network is re-trained using cropped segments of the satellite image of the disaster. The data were obtained from a publicly accessible source, the Copernicus EMS system. They provided three channel (RGB) reference and damage grading maps that were used to create the images of the ground truth and the damaged terrain. I then retrained the final layer of the network to identify civil structures that had been damaged. The resulting network was 85% accurate at labelling the pixels in an image of the disaster from typhoon Haiyan. The test results show that it is possible to create these maps quickly and efficiently.

Show moreThis IPRO is designed to support the Department of Homeland Security national security initiatives as outlined by the United States Government. The goal is to design a project that supports homeland security compliance guidelines. For example, depending upon interests of the group, a software program could be developed containing a matrix of risk and preventive factors which could be used to assess how well an organization meets Homeland Security Guidelines. Items might involve public policy, computer technology, facilities, transportation, communications, EPA, security, water and air. The need to protect our facilities and people in the Chicago area given recent terrorist activities and the frequent, heightened state of alerts is critical. A well-defined homeland security project can help in contributing to the initiative of establishing homeland readiness. This hands-on project will afford students the opportunity to research an apply concepts of transportation, mechanical, electrical, power, economics, and especially computer technology and engineering to homeland security.
