All,</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=752081413-02032010>I need some help
creating a GeoTiff file. Basically, I've got a bitmap which exists over the
polar region. I think that a <FONT size=2>CT_PolarStereographic setting is
required to handle this, but I'm having problems with tiepoints and defining the
projection model. </FONT></SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=752081413-02032010><FONT
size=2>Basically all I know is the lat/long of the opposite corners of the
image. The first problem is the model definition. A <FONT size=2>ModelGeographic
model suggests to me that the tiepoint coordinates needs to be lat/lng values
(which is OK), but that the image has edges of constant of lat or long, which
this polar image doesn't. Also, it seems no possible to have a
PolarStereographic transform within a Geographic Model?. I could use <FONT
size=2><FONT size=2>ModelTypeProjected, but this suggests that I would need to
know the metres/pixel value which I don't. What is the correct
model?.</FONT></FONT></FONT></FONT></SPAN></FONT></DIV>
