I have geographic data for the road network.
I changed my data from a geographic coordinate system (blue line) to a projected coordinate system (red line), it worked perfectly for all of my data, except for one year.
As you can see from the second image, a horizontal red line (road) appears from the centre south of the island and stretches off the land.
To try and identify the road, I used the select features tool. It only identified the red line on the land, when I select it off the land, nothing appears (like the red line is not there at all)
Do you know why this would happen? Or, how I can fix it? If I remove the red line, then I will be removing part of my data.
I would treat it as measurement error, but the first map appears does not have this error.
