I want to draw several squares of 250 by 250 meters in the North Sea using QGIS 2.14. I need the coordinates of each corner as ETRS89 coordinates.
I created a new scratch layer with CRS EPSG:4258, ETRS89, then click "Toggle editing" and "Add Feature" with the Advanced Digitizing Panel open.
I click on a point on the map and press "d" to enter the distance. I enter 250 and press Enter. I then can click the angle.
After I finish editing, the 250 meter square looks small. When I measure it using the measuring tool it measures as 156 meters. Why is this, and how can I work with meters?
Also, why does QGIS not display units in any of the input fields? I know it depends on the CRS, but how can I know what unit is used for which CRS?
