I have a road network shapefile that I want to use to create multiple maps from it, each based on some selection of original shapefile. For example, I want to show all highways with some custom symbology and all bike paths with a different symbology both based on the road shapefile( so they are automatically updated whenever network is modified).
I don't want to create a new shapefile for each of them, as the whole purpose is to map these selections and see the changes as road network is updated. I think I was able to do this in ArcGIS by creating a new layer, but at least I can't find it in QGIS.
Thanks in advance.
Answer
The simple answer is to style you layer with an attribute to show the difference.
If you need to do anything more complicated you can do two things.
Use the rule based rendering
Open the layer more then once and set the query/filter for each layer to something different.
The first option is best if you want to show everything but based on more then one attribute. The second is good if you need to turn layers on and off to see only one or n types at a time.
