I don't think so - its not really set up for doing inter-layer references. I wrote a few lines of python that will do it though (assumes you have two layers loaded with names a and b in the layers list:<br>
<br>
reg = QgsMapLayerRegistry.instance()<br>
a = reg.mapLayersByName('a')[0]<br>
b = reg.mapLayersByName('b')[0]<br>
collection = {}<br>
index = QgsSpatialIndex()<br>
for f in b.getFeatures():<br>
index.insertFeature(f)<br>
collection[<a href="http://f.id" rel="noreferrer" target="_blank">f.id</a>()] = f<br>
<br>
with edit(b):<br>
for af in a.getFeatures():<br>
p = QgsPoint(af['lon'], af['lat'])<br>
box = QgsRectangle(p, p)<br>
for key in index.intersects(box):<br>
feature = collection[key]<br>
print feature['name'], af['name'], af['lon'], af['lat']<br>
feature['name'] = af['name']<br>
b.updateFeature(feature)<br>
<br>
<br>
<br>
Just paste that into the QGIS python console and it will update the name field of b with the value in a for the places where the attributes lon, lat in a intersect b.<br>
<br>
Please test in a sandbox before trying on your production data....<br>

Do you mean WMS? If so you can use this unofficial URI:<br>

<a href="http://aerial.openstreetmap.org.za/wms-ngi-aerial" rel="noreferrer" target="_blank">http://aerial.openstreetmap.org.za/wms-ngi-aerial</a><br>

I'm not sure if it has the most current imagery in it though - grant slater from OSM could probably comment on that...<br>

Just open QIGS, (or your *cough* other GIS app) and add a new WMS connection using that URL and it will work.<br>
