Which is vector file format does OGR use?

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.

Is the OGR library part of the GDAL library?

OGR is actually part of the GDAL library, so you will notice that some references point to GDAL (such as the mailing list). The OGR Simple Features Library allows MapServer users to display several types of vector data files in their native formats.

Who is the developer of the OGR library?

The main developer of the OGR library is currently Even Rouault (with original development by Frank Warmerdam) and the integration of OGR within MapServer was done by Daniel Morissette. Follow the instructions on the GDAL page to compile/install OGR/GDAL.

The CSV file volcano_data.txt contains the following fields, separated by a tab character ( ): Taken from The Geospatial Desktop book. This recipe creates a new table in an existing PostGIS database. The ogr2ogr command line tool is an easy way to filter, reproject and trim columns in a shapefile.

How to create a vector layer in GDAL / OGR?

GDAL/OGR has a Virtual Format spec that allows you to derive layers from flat tables such as a CSV – it does a lot more than that too so go read about it. In the example below we are reading in a CSV with X,Y columns and values. That CSV file is wrapped by an XML file that describes it as an OGR layer.

What does the command line ogr2ogr-formats return?

It’s always driven me a little nuts that the command line ogr2ogr –formats returns a ‘random’ list of drivers. This code returns the list of OGR drivers alphabetically from A – Z. . This code shows if a particular OGR driver is available. The exact names are the ones used on the OGR Vector Formats page in the “Code” column ( [ formats website ]).

What happens when you export shapefile to GeoPackage?

When you export a GeoPackage to Shapefile, QGIS converts the fid column to double (real) instead of keeping the original type (qlonglong, Integer64). And then the bug you reported occurs when you try to export this Shapefile back to GeoPackage.

Why is my shapefile not saved in QGIS?

I’m having problems creating new shapefiles – in QGIS 2.14.20 any new fields I create and any associated data are not saved. I’ve now got the same problem in QGIS 3.0, but there I get a message saying layer creation failed.
