[OSM-Talk-ZA] Updated CD:NGI Aerial Imagery Now Available

[Gerhardus Geldenhuis]

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.

Regards
