[Qgis-user] Getting lon/lat

[Jack Andersen]

Hi phi73,
You can get the Lat long for start and endpoints by using the field
calculator in the attribute table.
create a new field and calculate it with the following:
i.g. field "longXstart"  calculate: x(start_point($geometry))
"latYstart" calculate: y(start_point($geometry))

You can do the same for the endpoint by changing start_point with end_point

Furthermore the output will be in the same projection/coordinates as your
layer, but you can do a transform command on the above command with:
x(transform(start_point( $geometry), 'EPSG:25832', 'EPSG:4326')) where the
first epsg code is the current projection and the second one is the target
projection
I have moved the x to the front of the command because the transform
function only works on coodinate sets and i therefore transform x and y and
then extract x.
