I am using a data that represents urban areas. I display the label field when the area is of a certain minimal size. This works great, but on closer inspection I have noticed 'Unk' being displayed at places. This doesn't happen often, but often enough to be a concern.
<br><br>I links below are images showing this.<br><p><span id="image_dg__ctl3_lbl_url"><a href="http://img.auctiva.com/imgdata/0/1/6/7/2/6/webimg/5867510_o.jpg">http://img.auctiva.com/imgdata/0/1/6/7/2/6/webimg/5867510_o.jpg
