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.
