This image
represents a more realistic scale of what Kentucky HydroGrafx
will provide in the upcoming products. The area shown to the
left is approximately 5 acres. Sidescan imagery will be provided
on very large scales. For example, it is likely that 2500 acres
or more will be scanned in Blood River alone.
This image
is a sidescan of a known roadbed that runs roughly northwest
from the bridge (shown above). The major roadbed is on the left
side of the screen. Another roadbed (much less distinct) show
on the right side.
Structural
objects usually show up as brighter returns, plus they will
typically cast a shadow. Many times, the "shadows"
are as important since they give clues to the height and detail
of the object.
Notice the
very distinct objects just to the left of the word "sonar".
See the shadows!
If you look
closely, you can see other objects along the base of the roadbed.
The most
prominent feature is on the south end of the roadbed. We believe
it was where a culvert crossed below the roadbed and the 2 objects
are end support structures.
