[GIS] QGIS moving the layer/all features using Vector Affine Transformation

affine transformationqgisqgis-pluginsvector

I'm using QGIS to analyse some flight tracks which were produced using a different software. Now when they are on QGIS the reference point of everything is on 0,0 which is the aerodrome reference point.

But in real world this aerodrome reference point is a value in Easting and Northing. i.e. Easting=286499.025 Northing=6230965.204, so the everything else (runway ends, tracks points should be exactly as they are in the real world)

I did some research and found the Vector Affine Transformation plugin. Now using this how can I move everything to the reference point of Easting=286499.025 Northing=6230965.204
Easting = X and Northing = Y.

I'm having trouble understanding the plugin's matrix.

As indicated in my answer to How to compute parameters for QGIS Affine transformation?, you can do it after you recognize the different parameters of the matrix.

Parameters are: 

a: Scale X 
e: Scale Y
d: Rotation X
b: Rotation Y
c: Translation X
f: Translation Y

enter image description here

So, you should be able to move your layer by setting c and f parameters with your x and y values, i.e., c=286499.025 and f=6230965.204.

Special attention must be given to setting the map reference system beforehand. Hopefully, both the RS you set and your original data are in the same unit (e.g., meters), otherwise you might need also to apply a scale factor to your data.
