I'm connecting to WFS layer by qgis. On some layer I've got points features and few multi-point features. Whole layer contains about 1000 features, how can I do some query just to know which features is multipoint geometry?

  • Do you really have a mix of Point and Multipoint features, or do you have all Multipoint features, and you want to select those that have more than one point within them?

  • @smithkm yes, when I was trying to export to shapefile I've got message, that geometry type is mixed, and I need to default one type of geometry..

Export the Geometries into CSV format with a WKT (well known text) field containing the types. Load the CSV into Spatialite using QGIS's Qspatialite plugin. Run an SQL SELECT WHERE WKT LIKE "something%something" to search for the strings that are indicative of the data types you are looking for.

To create a WKT field, export the shapefile (other formats?) by typing GEOMETRY=AS_WKT in the OGR Layer option, of QGIS SAVE AS, then Save As CSV and QGIS. The WKT field should have the data you build your SQL SELECT statement with.
