I spent the past 3 days trying to workout why all of the sudden my tms imagery provider is giving me 401s. I finally came across this open bug report http://josm.openstreetmap.de/ticket/8050 This bug still exists today in build 5759 when using a tms or wms server with http basic authentication.

Temp hacky fix: I had to setup a mapproxy server just to hand over the credentials, but for some reason it won't let me zoom past 19.

I discovered the problem after using Fiddler and no Authorization: Basic was sent in the request.

If anyone has a solution to please let me know.

Did around 1 hour of driving to take footage of street signs and tracking data. Gets a bit embarrassed after a while going round and round, I went round an estate using keep left then goto centre as my method of getting all the roads. Unfortunately one street was blocked by a truck.

I wish there was an automated method of extracting street signs -> possibly use a mechanical turk to OCR them.
