Dear Tom, You need to get your projections correct.
The Google view is probably an orthographic map projection. This is a
long-standing projection type that gives you a view of a single hemisphere as
you would see it from e.g. the moon. It should not make any difference what
your rotation is as you should be able to correct that to put north back at the
top. I haven’t looked into it but you might be able to specify rotation
as part of the projection, in which case Mapinfo should automatically rotate
your vector layers to fit the image. If you need to reproject the image then
you could use Blue Marble (and even via our web site perhaps!). Of course I would not expect Google to
make things easy by actually telling you what the projection parameters are. It
may also be that once you are zoomed in to a small area that they switch to
Plat Caree (i.e. lat /long) or something rectangular and easier to deal with. I have been following this discussion with
some interest and we are now offering our datasets, like Postcode boundaries,
in Google format. Regards Tim Dr Tim Rideout Director Visit us at the AGI Scotland Event -

[mailto:[EMAIL PROTECTED] On Behalf Of Tom Thomson Playing around with Google Earth, it is pretty amazing. Question
tho...if I tilt the image to an oblique angle and save that image to bring into
MI.The image will not be georeferenced as it is only a JPEG.
However, if I have the GPS points for some areas on the image to register it in
MI, then the image ought to be spatially correct...or not due to the tilt??? If it is not spatially correct as above, then if the image is/could be
saved as a georef image (with the tilt) and brought into MI, then it would be
spatially correct?? tom ============================================================== |
