Filter for geometry types
|Assigned to:||Victor Olaya||% Done:||

I´d like to see a tool for filtering features based on the geometry type. For example:
That would help me select and work with specific parts of a data set.

i do not understand this...
I assume that you mean taking a vector layer and outputing just the features it contains of a given kind, in case it has mixed geometries (I d onot know if QGIS supports that...). That makes sense with pts, lines and polygons...but not with raster and no geometry.
Could you please give more details?

In quite a few cases, I work with more than one data set, so I usually work with vector, raster and table data, for example SHP-files, TAB-files, PostGIS, SQL Server, text files, DWG-files, GoeTIFFs, DEMs etc. Therefore, my projects contain a lot of data in different formats and geometry types.
I´d like to see a tool that can filter the data according to its geometry type. Databases can, for example, contain features with or without geometry and if I remember correctly, so can TAB-files. I´m sure there are more examples.
I suggest doing this one step at a time, for example starting with filtering polygons, lines and points. If this seems useful to more users, additional geometry types can be added later on.
