The PICC shows nothing more than the road border.
The PICC has a 20cm precision, is extremely well done and we can trace it (not to be confused with "copy"). I often *highly* recommend to use the PICC with JOSM in Wallonia. In fact, I'm spending much time to use them to correct what is neigbouring what I'm mapping. Often, for example, the buildings are traced as roofs based on imprecise, vague aerial photos. PICC shows building bases instead, very cleverly and precisely calculated from multiple photo angles. And with Area Selector, one can trace a streetfull of houses in a single click each, including numbers. I've been asked why ID and Potlatch would be worse than JOSM. I don't know. Just that when I meet something to leave as is, I know and I can check that it's JOSM. See my picture. It's Potlatch. The "area" is offset 2 m on the right and 6 m on south. The building is 5 m away from its place and it has no number 2. The pedestrian crossings 2m and 5m, the wood on the right 6 m. Etc ... Often, more complicated maps are simply horrifying. The roads are mostly right but I believe that it's better to follow PICC's way choices closely to show that PICC was used. And PICC does the conversion of curved to straight lines for you. Mistakes are sometimes easily corrected with JOSM's Improve Way Accuracy, but it's harassing to spend much time doing that while other mistakes continue to be made. And mapping a new house is much, much faster than correcting a bad one. *PLEASE, PLEASE* use PICC with JOSM in Wallonia !!! Wallonia have lost 6 years while I was trying to have the SPW correct their PICC server's mistake and I was helping JOSM to improve. JOSM is not really difficult to use. Use it more ans more in parallel with another software, which you can use when you're stuck until you find out how to do it with JOSM. You will appreciate what more you can do with JOSM.
