<div dir="ltr">Thanks for the efforts Grant. When you say errors, what does this mean? Does it mean tracing using the imagery surrounding erross will be inaccurate? Can we help with conversion/fixing work? Out of curiosity are you using a "USB disk network" to move the data. That's a lot of data even for fast UK networks.<div>

<br>
Updated: <a href="http://aerial.openstreetmap.org.za/" target="_blank">http://aerial.openstreetmap.org.za/</a><br>
<br>
Contains new imagery (collect from CD:NGI during November 2012) and<br>
I've finally filled in most of the missing areas.<br>
<br>
Percentage of the imagery captured in the year:<br>
- 2012: 17.8%<br>
- 2011: 27.6%<br>
- 2010: 21.1%<br>
- 2009: 28.8%<br>
- 2008: 4.7%<br>
<br>
The aerial imagery (as supplied) is 3004 GigaBytes and made up of<br>
45454 tiled GeoTIFF files.<br>
Combined they would make an image: 3256402 x 2875186 pixels or 9.3<br>
Million Megapixel ;-)<br>
<br>
The imagery is available in JOSM and Potlatch2 as a background layer<br>
using the "South Africa: CD:NGI Aerial" preset.<br>
Please remember to add the "source=ngi-aerial" tag when using the<br>
imagery. In Potlatch2 this can be done by pressing "B" when the new<br>
imagery is set as the background.<br>
<br>
There are 3 errors I am aware of:<br>
- Black missing strip near Victoria West, NC<br>
- Black missing square near Villiers, FS<br>
- 2 Black thin strips, 1: just east of Mooi River, KZN and 2: just<br>
west of Greytown, KZN<br>
The errors will get fixed when I have a chance, but are not currently<br>
a high priority.<br>
<br>
The imagery should also finally be moved to a beefier/faster server<br>
within the next 24 hours.<br>
<br>
Regards<br>
Grant<br>
