Aerial
photographs and maps show the surface of the ground and things resting
or happening on it at Superfund, dumps, industrial and other environmentally
relevant sites. Aerial photos taken at different times show what was happening
when each photo was exposed. But beyond this, the goal of environmental
forensic photointerpretation must be to use that information to inform
experts and attorneys about what happened between aerial photo dates,
and to correlate industrial, dumping and other processes and patterns
on the surface through time with underground contamination. The first
step in doing this is to register photointerpretations through time and
subsurface sample data together in a single spatial database. State-of-the-art
digital mapping and subsurface visualization technologies are used for
these purposes, and for analysis. |
