Unknown exception when moving whole polygon layer features using QGIS [closed]

Question

I upload in QGIS canvas 2 polygons layers: Buildings with 100432 features and Census units with 2876 features.

They should be aligned and perfectly overlapped but they aren't (i.e., some buildings are beyond census units edges). So, I am trying to move all features of Buildings layer by selecting all features with a circle, activating the editing tool and then moving all of them.

Unfortunately an error message of "unknown exception" is shown. While, if I do the inverse, i.e. I move the Census Units, which is less suitable solution for me, it works.

1. Do you know which is the reason?
2. I suppose that another solution could be changing the reference system, but can someone tell me, if needed, which criterion adopting for it?

Answer 1

If you need to shift the input layer, you can use the QGIS processing tools and in particular Translate:

process:

1. draw an origin point on a vertex and read the coordinates
2. draw a second destination point and read the coordinates
3. make the difference of the coordinates and use them in the Translate algorithm

Move vector layer based on YX (Meters)

Answer 2

If you need only to move the input layer, you can use the great gdal/ogr

ogr2ogr output.shp input.shp -dialect sqlite -sql "SELECT fieldOne,fieldTwo,ShiftCoords(geometry,-11.869,60.133) FROM input"

-11.869,60.133 are shiftX and shiftY.

Note: fieldOne,fieldTwo are all the input fields except the geometric one
