Hi, sorry i didn't realize that you had sent a comment ; i understood now the derelict canal. Also, about your second comment, when visiting the place, i tried to follow the path above the road D117A, but i could not find it anymore after 50m. But i guess i was not patient enough with dealing with the vegetation. I checked on the LIDAR MNT layer that indeed there is a path on the ground as you indicated. I resurveyed it using LIDAR MNT and removed the "fixme" tag. Is that fine for you ? Sorry for the delay in my answer.
