<p class="MsoNormal">Upon updating mapserver, projections for the features we use in our webapp were off.<o:p></o:p></p>
</div>
<p class="MsoNormal">We updated from version 7.0.7 to version 7.4.1. I'd like to stress that nothing else changed in setup during testing.<br>
<br>
In the images below you can see the situation before (left) and after (right). The blue lines are polygons representing seamlines for the orthomosaic of aerials we are using.<o:p></o:p></p>
