This page lists useful batch file examples for using ogr2ogr.exe. For complete documentation on this tool please visit gdal.org/programs/ogr2ogr

Basic Format Conversion

Format conversion can be done using "-f <format_name>" then specifying the "<destination_filename> <source_filename>".

SHP to GPKG

ogr2ogr.exe -f GPKG 2d_code_M01_R.gpkg 2d_code_M01_R.shp

MIF to SHP - assuming only one geometry type exists in the MIF file

ogr2ogr.exe -f "ESRI Shapefile" 2d_code_M01_R.shp 2d_code_M01.mif

Bulk Format Conversion


Convert All Files Within Folder to GPKG

ogr2ogr.exe -f GPKG all_layers.gpkg ./path/to/dir

Convert All Files Within Folder to GPKG with Wildcard

ogr2ogr.exe -f GPKG all_layers.gpkg ./path/to/dir/*.shp

Convert All Files From a GPKG to a SHP

ogr2ogr.exe -f GPKG ./path/to/outdir all_layers.gpkg

Convert Single Layer To/From GPKG


Convert Single Layer From GPKG - Uses an SQL statement to select all features from a given layer

ogr2ogr.exe -f "ESRI Shapefile" -sql "SELECT * FROM '2d_code_M01_R'" 2d_code_M01_R.shp all_layers.gpkg

Convert Single SHP Into a New GPKG Where Layer Name is Different From Database Name

  • -nln <layername> - assigns the name of the layer within database
ogr2ogr.exe -f GPKG -nln 2d_code_M01_R new_database.gpkg 2d_code_M01_R.shp
