All,<br>
<br>
I would like to know who in Africa is using OpenLayers. I have been using
OpenLayers for almost a year and have been battling to get the grid extents for
Southern Africa. The ones I am using is -180.0,-90.0,180.0,90.0. That basically
gives the grid for the whole of the right half of the Southern Hemisphere, with
that, all the tiles as well. Least to say, it is not the most responsive method
to use. Any help would be appreciated.<br>
<br>
I have been asked if all responses be done via the list and not directly
to my email address.<br>
