Is it possible to add an extra column with a specific value on SpatiaLite using ogr2ogr?

What does ogr2ogr do?

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 is an ogr file?

What is OGR? ¶ The OGR Simple Features Library is a C++ Open Source library (and command-line tools) providing read (and sometimes write) access to a variety of vector file formats including ESRI Shapefiles, and MapInfo mid/mif and TAB formats.

What is dialect for SQLite?

The SQLite “dialect” can be used as an alternate SQL dialect to the OGR SQL dialect. This assumes that GDAL/OGR is built with support for SQLite, and preferably with Spatialite support too to benefit from spatial functions. The SQLite dialect may be used with any OGR datasource, like the OGR SQL dialect.

What is the difference between OGR and GDAL?

In basic terms, GDAL is used for reading, writing and transforming raster data, while OGR can do the same with vector data.

What is ogr to ogr?

ogr2ogr – this is a command line tool that converts one Ogr defined data source to another Ogr data source.

What is OGR SQL?

The OGR SQL dialect adds the geometry field of the datasource to the result set by default. Users do not need to select the geometry explicitly but it is still possible to do so. Common use case is when geometry is the only field that is needed.

How do you use OGR?

What is an ogr dataset?

What does GDAL do python?

The GDAL Python package provides a wrapper around the GDAL C++ library that allows for using its functionality in Python. Similar support exists for other languages and it is also possible to use GDAL/OGR commands from the command line of your operating system.

How do I install ogr2ogr on Ubuntu?

To get the latest GDAL/OGR version, add the PPA to your sources, then install the gdal-bin package (this should automatically grab any necessary dependencies, including at least the relevant libgdal version). Once you add the repository, go ahead and update your source packages.

What is GDAL bin?

GDAL is a translator library for raster geospatial data formats. As a library, it presents a single abstract data model to the calling application for all supported formats. The related OGR library (which lives within the GDAL source tree) provides a similar capability for simple features vector data.
