Remote Sensing Classification of Hurricane Storm Surge Structural Damage

摘要

The concept of spatially-tiered reconnaissance has been introduced as a method of providing increasingly detailed levels of analysis in post-disaster situations[Adams 2006, Womble, 34-38]. Remotely sensed data is becoming more widely available on a systematic basis following natural disasters at various spatial, spectral and temporal resolutions. Depending on these resolutions, each dataset is capable of providing different levels of information. Figure 1 illustrates the three tiers that are used within spatially-tiered reconnaissance – Tier 1 (Regional), Tier 2 (Neighborhood), and Tier 3 (Per building), using storm surge damage sustained after Hurricane Katrina as an example.
