Abstract:n the Access Restoration Project Task 1.2 Report 1, the algorithms for detecting roadway debris piles and flooded areas were described in detail. Those algorithms take CRS data as input and automatically detect the roadway obstructions. Although the location of obstructions are a valuable information product, it is beneficial to take the processing a step further and characterize the obstructions in terms of size. For debris piles in the roadway, this means calculating the volume. For flooded portions of the roadway, this means calculating the depth of the water. Not only does this additional information allow someone to look at a map of the obstructions and determine their severity, but it also feeds into the Access Restoration module to determine restoration times and optimal routes.
