[OSGeo Africa] FW: Being dumb

[Gandalf the Gray]

Hi Grant (and Aslam)

I downloaded this from https://ngigeoportal.dlrrd.gov.za/cdngiportal/.

Instead of downloading the 2528CA 1:50 000 map from the portal, which I am
very familiar with, I must have clicked somewhere that I indeed up with a
provisioned file of around 25GB with the zip containing the files
2528CA_0.ige, 2528CA_0.img and 2528CA_0.pyrx.

I later went through the whole portal, and especially looked in the
Imagery/Aerial Photography and Imagery/Ortho_rectified subsections, but
could not find anything close to what I ended up with.

I have downloaded numerous data sets from the portal including imagery, and
the provisioning of the download file took not a lot of time.  Imagery was
always in tiff format, but this one ended up in .img format, and took over
three hours before I got the download link.

I downloaded the 2528CA and 2528CC maps late yesterday, and also ended up
with .img files, so I do not know why it is supplied in .img format now.
Maps I downloaded (if I can recall, as my last map download was on the old
portal, over a year ago, and that was in tiff)

If this helps, the provisioned file was named
provision-C923hluRQbKsSqfGW38hAQ.zip, so the provision job was
provision-C923hluRQbKsSqfGW38hAQ.
