<p class="MsoNormal"><span style="mso-fareast-language:EN-US">After
a quick look at the data available for parts of Zambia I
know well I would suggest that caution is used. I had a
look at areas in the middle of Lake Kariba and there are
buildings marked that are obviously boats or what are
known as Kapenta rigs used for netting kapenta, a small
sardine like fish. I also did a quick check in the Kafue
National Park where there should be very few buildings and
I suspect ant hills are being mapped here as buildings,
something remote mappers tend to do as well. Africa is
already full of very poor data, adding to it would not
help in any way.</span></p>

<p>Apologies if I'm repeating myself to anyone here, but in cases
such as this I'd suggest commenting politely on the changeset
explaining why some things that have been added as buildings
aren't in reality buildings. Mappers taking part in remote
mapping projects in Africa are often new to OSM, and in some
cases haven't always been given given the assistance they need
to tell if something really is a building, and if so how to map
it well (for example, make it rectangular, if it's rectangular
on the imagery, by pressing "q").</p>

<p>I believe the remark was referring to buildings in the google
dataset, not in OSM.</p>
<p>That said, as has already been said, the google data is off
limits till a waiver has been obtained from google legal

<p>Naturally there's a parallel discussion to be had on what the
utility of the google data for OSM is in the first place .</p>
