All my data including photos, laser scans and GCPs are in this local coordinate system.</p> <p>I have seen what ContextCapture uses as an internal local coordinate system is centred on the dataset. Do I need to create a custom user coordinate system to ensure the site local coordinates will be used instead of the internal application local ENU?</p><div style="clear:both;"></div>
