I have a situation where I need to merge a large number of spatial files into a single output with a free tool like QGIS, rather than FME or Alteryx.

Along the lines of this post: Merging multiple vector layers to one layer using QGIS?

However, I have some point features, some line features, and some polygon features. This rules out outputs like shapefiles, but anything else is fine like GML, TAB, or a database.

Is there anyway to do this in QGIS?

Every process or model I try makes a shapefile at some point which means this can't work.

  • You want to place them in the same database but as separate layers or actually merge together lines, points and polygons?

    I need a single table with a single geometry column (Or a single TAB file would be easier). No features are to be changed in any way.

  • A good point to start is to take a look at this post. I think you should consider using PostGIS to manage your datasets. Mar 31, 2017 at 13:57
  • Do all layers share the same attributes?

  • I believe Sqlite or Spatialite will allow multiple feature types (lines, points, polygons) in a single geo enabled table.

You can merge layers with different geometry types together with ogr2ogr.

Here is an example about merging an point shapefile and polygon shapefile into GeoPackage as a new layer "merged" that has a generic geometry type.

ogr2ogr -f gpkg merged.gpkg point.shp -nln merged -nlt geometry
ogr2ogr -f gpkg -update -append merged.gpkg polygon.shp -nln merged -nlt geometry

ogrinfo merged.gpkg merged
INFO: Open of `merged.gpkg'
      using driver `GPKG' successful.

Layer name: merged
Geometry: Unknown (any)
Feature Count: 2
Extent: (309.000000, 478.000000) - (599.000000, 604.000000)
Layer SRS WKT:
FID Column = fid
Geometry Column = geom
attr: String (1.0)
  attr (String) = B
  POINT (382 478)

  attr (String) = A
  POLYGON ((309 584,599 604,466 493,309 584))

However, you will have some problems with QGIS with using that layer because QGIS can't handle points, lines, and polygons on a same layer. QGIS requires that layer is split by the geometry type

You can open the merged layer as a single layer with OpenJUMP.
