[OSGeo Africa] South Africa Aerial Imagery

[Lore Sereetsi]

Hi Grant

I had a look at the link. Great imagery.
However, would it be possible to indicate the date by which the imagery was last taken (assuming the site will be up for a long while, updated data is always best). So far it seems to be more than a year old.
Also, perhaps an indication of some reference system (unless this defeats the purpose of it's intended use).

Regards

Lore K. Sereetsi

Hi Everyone,

I recently setup: http://aerial.openstreetmap.org.za/ using aerial
imagery available from CD:NGI.

The service is primarily for South African OpenStreetMap contributors,
but I don't mind others using the site for light usage*. I do not plan
to offer public WMS access to this instance.

Technical:
- Tiles are TMS, Top Left origin in EPSG:3857
- Source imagery: 45454 GeoTIFFs, 3004 Gigabytes
- Currently: Lighttpd, mapserver (fastcgi) and tilecache (fastcgi)

Feedback appreciated.

HELP!
I am currently missing the following source files, I would really
appreciate online access to them if you have them (or willing to
collect the files from CD:NGI in Cape Town and put them online.)
- 2728BA, 2728BB, 2728BC, 2728BD
- 3123AA, 3123AB, 3123AC, 3123AD
- 3123CA, 3123CB, 3123CC, 3123CD

*: Plug... I am available to contract to setup private instances.

Regards
Grant Slater
