yet. A similar error when some stores in a chain have shop=yes and the<br>
others have a more detailed tag (or even different tags). That being<br>
said, I too am interested in data quality enhancements, especially when<br>
it comes to information maintenance and consistency.<br>
<br>
The country where I am (Iceland) is sparsely populated outside the<br>
capital area (bar a few small-ish areas). The distribution of OSM<br>
volunteers around the country is not in favour of good overall<br>
information maintenance and going to each municipality every year or two<br>
to review the information locally would be too expensive. Sometimes we<br>
in the community know some people in various parts of the country who<br>
are interested but are not so ready to commit to use a dedicated editor<br>
(or even iD) on their desktop. Then there is the increasing flow of<br>
tourists and some of them (thankfully) contribute corrections.<br>
<br>
The problems start to occur when the area seems complete and/or has "too<br>
much information". How can one know a POI has been reviewed recently<br>
(enough) or not? If I were to walk through a shopping street to verify<br>
POIs on the way, how could I be fairly sure I wouldn't be duplicating a<br>
similar effort made by another user just the day or week before? Or if I<br>
were to enter a small town in the country and have some spare time to<br>
review the area.<br>
<br>
One QA tool I would really like is a smartphone app which would offer an<br>
interface where people can verify that the information associated with<br>
the POI is still correct or, if it isn't, either correct the information<br>
in the app or mark the place as such for someone else to do it. After a<br>
certain time interval, the POI is marked again as pending review. Then<br>
one would only need to convince someone local to install that app and<br>
check it a few times a year while in their town (or even when they<br>
travel to the neighbouring towns).<br>
