Select Entire City to adjust the lat long being off by about 300 feet east or so

Petersburg, Alaska I would like to edit this map but with everything being off it is very difficult to fix. Is there a way to select everything in the current view so that I can roughly move it?

Check it out this Alaska Overlay is accurate I checked it with my gps running in my vehicle carputer. Here is the URI for the tiles if it doesn't show in the editor.

If you want to roughly move it I would suggest using the JOSM editor: it allows more rapid selection of large number of objects than Potlatch (the online editor). You can select multiple objects with Potlatch using Shift-click, but it can be frustrating to lose a large selection through inadvertently clicking in the wrong place.

However, looking at Petersburg, I think you'd be faster realigning by hand. You have typical poor TIGER data, but with a manageable volume of data. The simplify line tool (bottom left in the tool menu) in the on-line editor Potlatch will help. I'd drag the intersections to their correct locations, and then use the simplify line tool to straighten out each street.

A far bigger job is getting the coastline more accurate, and this needs to be done by hand anyway.
