Hi,
The original file is rotated. You can check it with gdalinfo tool
gdalinfo 2002.tif

OpenJUMP does not support rotated images. You can turn the original image into
a non-rotated image with gdalwarp
gdalwarp 2002.tif 2002warped.tif
Resulting image has this gdalinfo:
Corner Coordinates:

You can open this warped image with driver "GeoTIFF plus (JAI)". Many other
drivers give me NPE. Once open you can see that the real image appears rotated
in the middle of the image box with triangular slivers at the corners.
Conclusion: This is more like a missing feature in OpenJUMP than a bug.
However, opening a rotated image without rotating it and without telling any
message for the user is not especially good behaviour.

That should show the shift.
I tried to open the image with all of the available raster drivers in the
latest official version of OpenJUMP and in the nightly build from December 30th.
The images and vector linework should both be in California State Plane
Coordinates Zone 3 US Survey Feet.
It looks like there is both a shift and a slight rotation problem.
Thanks for any help.

Hi,
I can check your images and their footprints. Tell me also which OJ version and
which raster driver you have used.

Thanks for any help.
