I'm asked to work on some road shapefiles and create a map out of it. The problem is that some of the shapefiles doesn't have a coordinate reference system which then I noticed that they don't have .prj files.
I tried defining their projection (WGS 84, same as the other shapefiles) using Define Shapefile Projection tool in QGIS which created .prj files for them but when I put a base map, they're in the middle of the sea. I even tried Define Projection in ArcMap but it has the same result
