Variable General Info
Demographic population metric of interest ?Comment:Optional. When estimating the exposure of coastlines to erosion and inundation due to storms, it is important to consider the population of humans that will be subject to those coastal hazards. Based on an input population raster, The Coastal Vulnerability model reports the average population density (people per square kilometer) in a user-defined radius around each shore point. Specifically, the model takes the average of all the non-nodata population pixels within the radius, and divides by the area (in sq. km) of one population pixel. The input population raster may contain any relevant demographic population metric of interest, not strictly total population. For example, it may be important to summarize the population density of only a vulnerable portion of the population, such as eldery or children. |
