Ultraviolet is good for discriminating oil on water. Unfortunately, ultravi=
olet is also scattered by the atmosphere more than visible or IR - UV isn't=
suitable for satellites but can work on a low altitude plane if haze or hu=
midity isn't too high. Radar can also be used, but radar is much trickier =
than most remote sensing - people are used to interpreting optical images, =
and radar images have different geometry.=20

Hi,
=20
1. Is there a very practical, well tested and trustable way to identify oil
spills (small scale) in open sea areas from spatial (satellite) imagery. In
general I'd need a "hands on" tutorial (satellites, bands, processing,
resolution, etc...) on this subject. Should sound like "detecting oil spills
in oil drilling platforms from satellite imagery" or whatever :-)... Does
anybody know of any ?=20

2. I'm also collecting all possible info on methods used to eliminate
various sampling-related artifacts (is there any classification of these ?)
from bathymetric DEM's. Especially on data handling prior to interpolation
although post-interpolation techniques are also of some interest.=20

3. Hmmmm !.. What are these guys doing there :

What makes me angry is that I am not a spammer and this http://www=20
securitysage.com/spam.html seems to not exist at all (or at least it is
impossible to get it into my browser). What should I do now to get back my
right to post messages to the GIS list from my preferred e-mail account ?
=20
Thanks in advance...
