Im working with these shapefiles:
They show pipelines & electricity grid of the UK. They do not have a .prj file included in the shapefile.
They display fine in QGIS when layered on top of each other, but I need to know which projection they are in so I can display them on a world map.
The x and y values are very large so I tried the Universal transverse Mercator projection "WGS84/UTM zone 30N ESPG:32630" because the UK is in zone 30.
This placed the shapefiles at the right scale, but just above the equator by Ghana (48 degrees too far south and 3 degrees too far west).
This seems to imply that the shapefiles' coordinates are zeroed half way between UTM zone 30U and 31U.
Does anyone know which projection I should be using?
Thanks for your help.
