Hi David,
Is this a gridded terrain image i.e. an interpolated terrain from the
unevenly sampled lidar ? or is this a representation of the return
intensity ? I would recommend tin generation and gridding follwed by
some rough statistics on deviation from actual ground point values.
For the interpolated intensity I am not sure what would be the best test.
Cheers,
Tisham.

All,
I'm writing a plugin for ossim to form an image from las files. This
will be open sourced as soon as it's useful. Does anyone have any
advise on how to choose a grid resolution which will determine the
lines and samples? I thought about using the square root of the
number of points for a return and then scaling by ratio of the
bounding box. It would be nice to pick a grid size that gets at least
one point for grid. Any ideas?
Thanks in advance,
Dave
