What is the name of the geometry in OGR?
So the name of the geometry is “OGR_GEOMETRY” for the OGR SQL and either “GEOMETRY” or the real name that is used in the datasource for the SQLite SQL dialect. The best thing is to read the documentation, which is now here: https://gdal.org/user/ogr_sql_dialect.html
How to select the geometry type in ogrinfo?
The OGR_GEOMETRY special field represents the geometry type returned by OGRGeometry::getGeometryName () and can be used to distinguish the various types. By using this field one can select particular types of the geometries like: ogrinfo -sql “select * from test” test.shp INFO: Open of `test.shp’ using driver `ESRI Shapefile’ successful.
How is OGR used to import non-spatial data?
Using OGR to Import Non-spatial Data While OGR was designed primarily to transform data between different spatial datasources, it is a little known fact that it can be used as well for importing non-spatial datasources such as Dbase files and CSV files. Importing Dbase file into PostgreSQL using Ogr2Ogr
Where can I find the OGR toolkit binaries?
The OGR toolkit is a subset of GDAL project. GDAL is available on many operating systems including Linux, Unix, Mac, and Windows. You can find binaries at GDAL Binaries. It is also included as part of the QGIS Desktop.
What do you need to know about ogr2ogr SQL Server?
After importing any data, OGR2OGR will create two additional tables in your SQL Server database – spatial_ref_sys and geometry_columns, which store metadata about the spatial columns in the tables. These tables can be safely ignored (or deleted) – OGR2OGR will recreate them after each conversion anyway.
When do fields get skipped in OGR 2.0?
A field is skipped if mentioned previously in the list even if the input layer has duplicate field names. (Defaults to all; any field is skipped if a subsequent field with same name is found.) Starting with OGR 2.0, geometry fields can also be specified in the list.
What can ogr2ogr be used for in GDAL?
ogr2ogr can be used to convert simple features data between file formats. It can also perform various operations during the process, such as spatial or attribute selection, reducing the set of attributes, setting the output coordinate system or even reprojecting the features during translation.
What can ogr2ogr do in the translation process?
It can also perform various operations during the process, such as spatial or attribute selection, reducing the set of attributes, setting the output coordinate system or even reprojecting the features during translation. Output file format name, e.g. ESRI Shapefile, MapInfo File , PostgreSQL.

Is the geometry column in geom or CRS?
The geometry column is geom and the CRS is in meters, so that the distance 100000 is realistic. You are trying to use wrong tool for updating your GeoPackage.
