Is there a tool or plugin in QGIS that resembles ArcGIS 10's Dissolve tool? I'm trying to dissolve several polygons (parks) around the boundaries of another layer of polygons (cities), while performing various calculations for multiple attribute fields (like summing their total area, doing a count of features, etc).
I looked into an earlier question (Batch Dissolve Polygons based on Attributes in QGIS or FWTools) where ftools was recommended, but ftools doesn't allow you to specify the way you would like to summarize statistics for multiple attribute fields. Is there one tool that allows me to summarize statistics for multiple attributes, like the ArcGIS Dissolve tool?
