[HOT] How to handle task edge areas correctly?

Thanks Nick! 


In my case the features didn’t go only a little into the other tile, they went a lot (e.g. they were not ‘handed over’). The edge area instructions could be shortly mentioned with the task instructions (sort of Do’s and Dont’s ) so this kind of mistakes could be avoided. What would be the proper way to correct them? Should I do it as I spot the mistake or should I leave it to the person editing the other tile (note: I have no idea whether the other guy has noticed the mistake). I also find it problematic that I can’t see the features that exist outside of my square, is there a way to see them? (I’m using JOSM)

I am a beginner with HOT OSM. So far I’ve mostly digitized buildings regarding the Gorkha task (#1009). I’ve read the beginners tutorials but I haven’t seen what is the proper way to handle edge areas (maybe I’ve missed it).


1) if I find a road/path/track how that goes beyond my tile, how far should I digitize it? Only to the border of my task tile or as far as it goes? 

2) if I find mistakes from the edge area that are within another tile or that goes beyond my own tile, what should I do? 

and in general 3) how are roads/tracks connected between the tiles? 


For example this morning I edited a tile which had a lot of features that were poor in quality. A lot of this data was in another tiles area (landuse = residential). I get it that editing another tiles area might create problems, but in the other hand leaving poor quality data isn’t any good either.
