[Qgis-user] Question about city layer density

[Szilard Albert]

Joe,
what you seem to need is "scale dependent visibility".
To achieve this, go to "layer properties", "general" tab, and enable "scale
dependent visibility".
Set your scales as preferred. This will show or hide all your cities,
depending on the zoom level,
but you can make different layers with different classes of cities, and
enable/disable their
visibility at different zoom levels.
regards,
Szilard
