    <description>&lt;P&gt;Someone in here with experience in georeferencing using a&amp;nbsp;project zero point?&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I have a situation, when using project zero point and not using it yields different results:&lt;/P&gt;
&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Kamelite_0-1785754360816.png" style="width: 999px;"&gt;&lt;img src="https://community.graphisoft.com/t5/image/serverpage/image-id/104329i8088DDF87764961E/image-size/large?v=v2&amp;amp;px=999" role="button" title="Kamelite_0-1785754360816.png" alt="Kamelite_0-1785754360816.png" /&gt;&lt;/span&gt;&lt;/P&gt;
&lt;P&gt;This is where I do not use a Local zero point - and it looks like this: - perfect&lt;/P&gt;
&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Kamelite_1-1785754617674.png" style="width: 999px;"&gt;&lt;img src="https://community.graphisoft.com/t5/image/serverpage/image-id/104330iA5AEA8A0CF14A24B/image-size/large?v=v2&amp;amp;px=999" role="button" title="Kamelite_1-1785754617674.png" alt="Kamelite_1-1785754617674.png" /&gt;&lt;/span&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;The same building, using a Local zero point, the same corner:&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Kamelite_3-1785754735278.png" style="width: 999px;"&gt;&lt;img src="https://community.graphisoft.com/t5/image/serverpage/image-id/104332i864E501B7303107B/image-size/large?v=v2&amp;amp;px=999" role="button" title="Kamelite_3-1785754735278.png" alt="Kamelite_3-1785754735278.png" /&gt;&lt;/span&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;But a different result:&lt;/P&gt;
&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Kamelite_4-1785754828061.png" style="width: 999px;"&gt;&lt;img src="https://community.graphisoft.com/t5/image/serverpage/image-id/104333i22CE549179F73D21/image-size/large?v=v2&amp;amp;px=999" role="button" title="Kamelite_4-1785754828061.png" alt="Kamelite_4-1785754828061.png" /&gt;&lt;/span&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Any ideas? I have calulated the SP-distance using a tiny spreadsheet in Excel. I have used that same spreadsheet several times, but without tthis buggy result.&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;The only differens this time is the distance between the local zeropoint and the building, 500-600 meters, Can that distance cause that kind of&amp;nbsp;anomaly ??&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;.Kamelite&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
