Analyzing data relating to physical-plant damage within a geographical region involves mapping data points to depict the density of incidents producing the damage. Mapping the data points produces a density surface corresponding to incidents of damage occurring within the particular geographical region under consideration. That density surface is preferably depicted in conjunction with a map or other visual representation of the geographical region, providing a visual representation showing the location and frequency of damage to the physical plant within that geographical region. The mapping of data points may be updated from time to time, thereby providing updated mapping of damaged density surface against which efforts to reduce damage over time may be compared with the results of such efforts.
