Hi all,

Somewhere in my workflow i'm causing my 3D model to be inverted. I have a model with 400 photo's and 7 groundcontrol points measured in a arbitrary coordinate system with a Total Station (need high accuracy(<5mm) points!). I worked with Agisoft before, but this is the first time I work in an arbitrary coordinate system instead of world coordinate system

X range: 29.7664 - 70.0173 meter

Y range: 15.7528 - 47.3623 meter

Z range: 18.912 - 64.4892 meter

I need a DEM and orthophoto that are overlying each other to calculate volume of a part of the model (in ArcGIS for example). After alligning the photo's I placed the markers in the photo's and model and calculated the dense cloud and mesh/texture. I think the problem is related to the moment in my workflow where I calculate camera locations based on the coordinates? My cameras are unchecked and my markers are checked when I calculate the dense cloud, i'm not sure if this is correct.

Hopefully somebody is able to shed some light on my workflow or has some examples that also work with arbitrary coordinate systems.
