Thanks for the reply Dan!
I am working on this school project with Alex and we collected the data to characterize the sidewalks. We collected points for every 3-5 meters and as you mentioned we would like to assign those observations to the edge of the closest sidewalk polyline, so we can represent our data as line features.
Sidewalk lines are one line for each side of the block and there are only two vertices for each sidewalk feature, therefore split line at vertices tool wouldn't be able to do the trick. Is there any other tool we can use? We are considering creating lines manually. I am attaching a screenshot below; each sidewalk feature is shown in different color. Green points represent sidewalks with no cracking, and red ones are with cracking. I am also attaching a identify window screenshot from one of our points.
Cheers
