I thought I would try these two methods on the one area and compare the results for a street lined with shops on each side.
GPS traces have poorer accuracy in these areas as the shops have awnings over the footpath. Doing it on paper might solve some of these difficulties.

Attempt One. walking-papers. Area selected and downloaded. Wouldn't print out at home due to "technical issues". Printed it out at work and carefully brought the paper home. Took it to Corrimal and lost the piece of paper.

Attempt Two. geotagged photos. Took a late evening walk with the camera / GPS combo. Took the photos and recorded the way. Back at home some days later and all of those photos are non-existent, as the memory card failed earlier that day. Several attempts on forensic recovery of the data but it wasn't there to be removed.

Conclusion. Score is nil all and the shops still need marking on the map.
