<div dir="ltr"><span style="font-size: 12.8px;">Hi phi73,</span>
<div style="font-size: 12.8px;">You can get the Lat long for start and endpoints by using the field calculator in the attribute table.</div>
<div style="font-size: 12.8px;">create a new field and calculate it with the following:</div>
<div style="font-size: 12.8px;">i.g. field "longXstart" calculate: x(start_point($geometry))</div>
<div style="font-size: 12.8px;">"latYstart" calculate: y(start_point($geometry))</div>
<div style="font-size: 12.8px;"> </div>
<div style="font-size: 12.8px;">You can do the same for the endpoint by changing start_point with end_point<br />
<br />
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:</div>
<div style="font-size: 12.8px;">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</div>
<div style="font-size: 12.8px;">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.</div>

<div>How could it be done the easiest way in QGIS.</div>
