I am dealing with some data I need to get on QGIS. It's CRS should be ETRS89, but instead of longitude/latitude I only have X and Y coordinates, and as soon as I add the data as CSV layer it ends up at a place where it should not belong.
I use this CSV here: https://data.gov.uk/dataset/b5d2f859-9a06-47bc-8f09-89171cfe97ba/shropshire-brownfield-site-register It includes the X and Y coordinates and states it is ETRS89.
Within the CSV I have the coordinates. CordX: 3853505 and CordY -205876
and it should be ETRS89 but if I look at the area where the points should end up, as ETRS89 the coordinates should be more like.
X: -3.059671 and Y: 52.862264
Is there a way to import the CSV with these coordinates instead? (in QGIS) Or do I have to convert them prior manually? How do I do that in the best way? (it's a file with a total of ~1500 records).
