[OSM-talk] Cities with grids
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I've been adding a large city grid using Potlach and Yahoo Aerial imagery. Nearly every road is perfectly straight from end to end, so I've been only adding the ends, and leaving the middles unconnected, knowing that I can go back in JOSM, validate, find crossing ways, and join them without moving them. Except that I can't join them without moving them - all the perfectly straight grid aligned roads are now a bit wonky. There has to be a better way. Ideally, I'd like to tag all the intersections as floating, meaning that there position is not important, their true position is determined by the intersection of the ways they are part of. Editors could notice this, and when I drag a node at the end of a way, all the intermediate floating nodes positions would be recalculated. If I drag a floating node it would be untagged automatically. What do other people think of this idea? Would a tag floating=yes on nodes be a good way to impliment it? Does someone have the ability to write a tool to realign all floating nodes?

Hi, I've been only adding the ends, and leaving the middles unconnected, knowing that I can go back in JOSM, validate, find crossing ways, and join them without moving them. Except that I can't join them without moving them Why? JOSM has code to place a node at the exact intersection of two ways if you click reasonably near the intersection. Does this not work for you? (You'd have to have a several-months-old version of JOSM for the feature to be missing.) I have just re-checked - draw two ways forming a big X, place one node in the middle, it's spot on.

No I don't think it would be a good idea ;-) If tagging for renderers is a bad idea then tagging for editors is a bad idea as well in my opinion.

I think you may misunderstand what is meant by tagging for renderers. The bad idea that is tagging for renderers is when you put mark a river as a lake because lakes show in a nice shade of blue on the map, but rivers show only as a line for each bank. Or you put a feature in twice, once to show as an area, once to show as an icon because the renderer doesn't draw both by default like you prefer. There is another kind of tagging for renderers that is completely OK, for example, it's perfectly find to have a tag called osmarender:renderdirection that overrides osmarender's default name direction drawing policy. Having said all of that, that isn't what is happening in this case. I am tagging a point as floating because I haven't surveyed the point properly. I only know it's there because when I last visited the city I noticed how you could stand in the road in many places and see 10s of blocks perfectly straight in each direction, and I have carefully aligned the ends of the street (with Yahoo Imagery). Of course, if someone on the ground uses a survey-quality GPS, and finds the Yahoo imagery is off, it's going to be much easier for them to correct the 80 or so ends of the streets and have the rest fall into line rather than them have to correct all 400 points manually. Even if they are using JOSM's align nodes line tool.
