<div class="moz-cite-prefix">Hi Howard,<br>
<br>
I found the same problem.<br>
I did a vector spatial adjustment in ArcGIS and when it fitted well
in the north it was off in the south by approx 50m and
viceverca.<br>
So clearly there is a problem with the shapefiles and I'm sure it
is not simply or only a projection issue.<br>
<br>
I also have issues with the border interpretation along the
coastline and lake shores. The water boundary shapefile is
also out of alignment with the boundaries.<br>
<br>
Regards,<br>
Mike<br>

Hi Langen - thanks for that link!</div>

The archive has:
<ul>
<li>International boundary (line)</li>
<li>Districts (poly)</li>
<li>Regions (poly)</li>
</ul>
<div>All are identified as Arc 1960 latlon.</div>
<div><br></div>
<div><b>Problem</b>: 'Districts' does not line up with the other
two layers (shifted NNW by ~ 250m); the other layers line up well
with other vector data I have, so I suspect there's a
misidentification of datum - however, changing it to Arc 1950 or
WGS 84 doesn't seem to help. </div>
<div><br></div>
<div>Anyone have ideas on how to fix it?</div>
