In the parts I've looked at, some roads on Bing just don't exist any more! Bing is good for coastline where there has been no human development, but not good for anything else. Using Bing imagery to check for roads will create the classic GPS nav problem - OLD DATA = WRONG WAY!<br></div></blockquote><div><br></div></div></div></div><div dir="ltr"><div><div class="gmail_quote"><div>It is definitely a concern to use any old and outdated imagery, not just
Bing. But based on experience, Bing usually has the best alignment out
of all the available satellite imagery so it makes sense to refer to
Bing (at first). But any good remote mapper worth their salt should check other imagery as well to (hopefully) avoid mapping outdated roads and features.<br></div></div></div></div>
