JOSM/Plugins/Create grid of ways
Create_grid_of_ways is a plug-in for JOSM
I live in a City with a very regular form, streets are parallel, blocks are square. Since there are quite a few cities built with this structure, this tool should make it simpler to create a grid of retangular ways.
See the two images at the right.
You can find the JAR file for this plugin here. It can also be downloaded and installed directly from the plug-in tab in the JOSM preference dialog.
