I have a directory of GeoJSON files, which I want to load as layers into a single new GeoPackage file. According to the GDAL GeoPackage documentation, I can name my destination GeoPackage file, enter a directory of shapefiles as the source, and it will load them each as their own layer/table. Indeed, I've tested this with shapefiles, and it works.

When I try the same thing with GeoJSON files, however, I get this:

Unable to open datasource ./seattle_washington_osm with the following drivers.
-> GeoJSON

Is this simply not possible with GeoJSON files, or am I doing something wrong?


The "directory as dataset" is a specific feature of the shapefile driver. From http://www.gdal.org/drv_shapefile.html :

Normally the OGR Shapefile driver treats a whole directory of shapefiles as a dataset, and a single shapefile within that directory as a layer. In this case the directory name should be used as the dataset name. However, it is also possible to use one of the files (.shp, .shx or .dbf) in a shapefile set as the dataset name, and then it will be treated as a dataset with one layer.

Alternative approaches would be to load each file using a loop, or to convert to shapefiles first.
