[OSGeo Africa] Request for assistance with OPENGIS Studies

[Tim Sutton]

Hi Willem

Further to Gavin's reply, I would really encourage you to read this:

http://catb.org/~esr/faqs/smart-questions.html

If you ask extremely generic questions it is very difficult to answer them.
Show us what you did and exactly what got you stuck and it will be easier
to point you in the right direction.

Regards

Tim
