Title: ERROR LENGTH SHAPE BETWEEN AUTOCAD AND PHOTOSCAN
Post by: scannapieco on December 05, 2018, 03:12:47 PM
I imported in Photoscan one shape from a dxf file created with Autocad.
In Autocad the length of the shape is 156,8402 mt (see attached file).
In Photoscan the same shape has length of 156,902 mt (see attached file).
In autocad, the polyline was created with only straight segments.
What does this difference depend on?
Perhaps because of the fact that the dense cloud processed by Photoscan was made with the WGS84 system and instead the shape was imported into a different reference system, namely ETRF2000 EPSG 6707?
Thank you very much.

Alex.

Hello Alex,

Can you attach the DXF with the single shape that you are applying measurements to?
