ogrmerge.py

Merge several vector datasets into a single one. More information: https://gdal.org/programs/ogrmerge.html.

• Create a GeoPackage with a layer for each input Shapefile:
  ogrmerge.py -f {{GPKG}} -o {{path/to/output.gpkg}} {{path/to/input1.shp path/to/input2.shp ...}}
• Create a virtual datasource (VRT) with a layer for each input GeoJSON:
  ogrmerge.py -f {{VRT}} -o {{path/to/output.vrt}} {{path/to/input1.geojson path/to/input2.geojson ...}}
• Concatenate two vector datasets and store source name of dataset in attribute 'source_name':
  ogrmerge.py -single -f {{GeoJSON}} -o {{path/to/output.geojson}} -src_layer_field_name country {{source_name}} {{path/to/input1.shp path/to/input2.shp ...}}
