The are 2 sets of data available for positions of model flying clubs around the country. One is the CAA website document AIC 17.3.pdf which appears to be dated 2005 (at 04/14/2011). The other is the SAMAA management site, which will list all clubs after you log in (you need to be a SAMAA member, in other words).
If you load both sets of points (CAA and SAMAA) in Google Earth you can see many differences and anomolies.
If you load the old and new sets of points for one source, again you can see difference and anomolies. This is to be expected, but does not mean that the newer points are now CORRECT.
The inaccuracies in the CAA data are a concern because this is the data full size pilots will use to determine where they can or cannot fly safely. If the point is out of place by even 1 kilometer, the pilot may then overfly a model site unwittingly, causing danger to all concerned, and probably invalidating any insurance claims too.Here are examples of what you might see in Google Earth. Note the large area in the Northern Cape where there are no registered sites, but they used to exist in the previous CAA data.
