[OSM-newbies] Editing one way streets

[topo at joelertola.com]

Hi all,

I am trying to edit my neighborhood in Manhattan. I want to set the  
numerous one way streets in my area to render properly. I found it  
almost impossible to use Potlatch for this as you can only check the  
direction of one street at a time.

I downloaded JOSM and I found it easy enough to flip the direction of  
streets that go in the wrong direction. However it is still hard as  
there is no visual indication of which streets are one way and which  
are not. What I would like is a JOSM that will color the streets based  
on the oneway tag. If I could have all the streets marked oneway-yes  
as red, oneway-no as blue and streets without a oneway tag as yellow  
that would make this task easy.

I did look at the JOSM documentation (http://wiki.openstreetmap.org/index.php/JOSM/Plugins/MapPaint 
) and it seems like this is possible by creating a new style sheet for  
this. However the instructions are daunting to me. I did manage to  
decompress josm-latest.jar into a folder and I found the style file  
mentioned in the documentation. I would experiment with this style  
file to see if I could make the program color the map as I want but I  
have no clue how to turn the folder back into an application. I am on  
a Macintosh computer and the directions do not cover Macs.

Thanks for any help,
