I recently received an air photo of our entire city in .jpg format. It was rotated
about 20 degrees off from
tru north-south.
I opened it in MI, registered it so that the error indicators seemed very close, and
saved it.
If I open it and any other MI table (ie. image as a "backdrop") the whole bunch is off
by the same +/- 20
degrees. The vector map is rotated to match the correct location on the raster
instead of the
raster being rotated into correct UTM coordinates. Doesn't matter which I open first,
vector or raster.
Isn't the first table supposed to control the projection of the map?
I took the image into Photo Editor and rotated it about 20 degrees. It looks OK, but
I cannot be sure
that the actual rotation is correct.
Isn't registering a raster supposed to "re-orient" the raster so it displays the
raster pixels in the location
that were assigned during the registration process?
Any ideas?
