Is it possible to open and visualize and KMZ network link in QGIS. If so what are the steps involved?
Perhaps newer versions of QGIS will open kmz directly, but for now you need to extract the temp.kml file from the kmz and view that.
Get a zip reading program, I suggest 7 Zip
and open the zip file. With 7 Zip it is simply a matter of right clicking on the kmz, 'Open Archive' and drag the temp.kml to the file explorer or desktop (in Win7).
So you will probably have to download the kmz first if it is online. Perhaps you could post that link here?
