[OSGeo Africa] Adding the NGI 50 cm colour orthophotography as WFS

Fri Jul 8 03:00:37 PDT 2016

Hi Heidi,

Esri South Africa has a service for the NGI imagery between 2008 and 2012.
see this link:
https://www.arcgis.com/home/item.html?id=9d01fa9041264cb283c353a5a613c81e

and here is the url to the service itself:
http://webgis.esri-southafrica.com/arcgis/rest/services/NGI/RSA_NGI_AERIAL/ImageServer

Kind regards,

Pieter Holtzhausen
