That is some very cool visualisation work Craig. It really emphasises how flat the surrounding area is. The railroad embankment appears to be the highest point around for quite some distance. It also seems to highlight that the trees do not appear to have attained any substantial height, so poor soil conditions prevail or extensive land clearance took place some time previously.
The drainage ditch also suggests soft, boggy soil conditions.
Not directly relevant to the accident, but it indicates the difficulties that may have been experienced by investigators in finding and recovering buried items from the ground.
