I have mentioned many times (mailing lists and e-mail to taggers) that 
Bing zoom needs a per area JOSM offset correction.
Its a pity to notice careful mappers devote so much time making maps 
offset because of Bing.

I saw people sticking little flags on dog poop but one still has to 
watch one's steps.
There's an impressive amount of hardware 
<http://www.befr.ebay.be/sch/i.html?&LH_AvailTo=23&_sop=15&_ipg=200&_kw=dog%20poop> 
for that software, but nothing of what you need.
Resist using bags and putting them in the letterboxes, even if that 
raises the discussion among the concerned people.
But if you walk your own dog while prospecting numbers, you will feel 
the leash loosen at every danger ;-)

The PICC maps <http://cartocit1.wallonie.be/pw/index.jsp> contains very 
precise building mapping with street numbers.
You'll never do better than an airplane.
This is one, just one, of the reasons why I say it's of paramount 
importance for us to be able to use PICC.
People say that the government agrees to make it available but that they 
have no time to say yes.
This is why I wait and I'm doing very limited house numbering business 
presently.

Does anyone have an opinion or recommendation about such cheap devices 
<http://www.tinydeal.com/index.php?main_page=ws_search_result&is_search=1&inc_subcat=&search_in_description=3&keyword=wifi+gps&is_input=&keyword=wifi+gps&cPath=&categories_id=54&disp_order=3>?  
(there are other similar shops)
Usually, CN stuff is of fair quality but minimally documented and 
supported (e.g. no "MP4" games).
But that's different for Android, isn't it?
 >22€ means a risk of paying taxes, but, according to Test-Achats, it 
looks like it's only VAT.
