<div dir="ltr">Hi Aslam,<div><br></div><div>The DB is still posting the 2011 Ward boundaries at that eddress. The coastal polys from Mtubatuba northwards still have that 6200 m extension into the Indian Ocean. This must have fuzzed a lot of density calcs over the years. Is there a name for this aberration yet? There by Kou-kamma in the south the sea-grab is 1000 m. Are there other issues besides the generally crude adherence to natural boundaries? Do they fit the cadastres? Yes, we can all just fix it but great if there was a reliable source dataset.</div><div><br></div><div>Regards,</div><div>Chris</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div>Chris Berens, GISc<br></div><div><a href="http://www.mapland.co.za" target="_blank">www.mapland.co.za</a><br></div><div>+27 (0)82 567 9322<br></div></div></div></div></div></div></div></div></div></div>

I did see the one using "another layer", but that is problematic as when one is digitising (say) a town road network you would want to honour the straightness of the roads and then intersect them afterwards.<u></u><u></u></p>
