What does the writeogr function do in OGR?
The function is an interface with the OGR abstraction library for spatial vector data, allowing data to be written out using supported drivers. The drivers supported will depend on the local installation, and the capabilities of those drivers (many are read-only).
When do you get an error in OGR?
The error only occurred when all the Polygons objects had one exterior ring, and zero or more interior rings. The error led to the coordinates of the rings cumulating, because the rings were not emptied before assigning the next ring.
Is it advisable to use references in OGR?
Use of the references given is highly advisable, with searches in the archives of other software using GDAL/OGR.
What does the PRJ file in GIS stand for?
*.prj: the coordinate reference system represented as text. In a word, the *.prj file informs on the coordinate reference system in which the geometry coordinates are expressed. It is used by GIS software in particular when data with different CRSs are used.
Can a column be written out in OGR?
Only a subset of possible data slot column classes may be written out; if the function returns an error that the data type of stated columns is unknown, examine the classes and check that they are one of c (“numeric”, “character”, “factor”, “POSIXt”, “integer”, “logical”), and if not convert to such classes.
How to write spatial vector data using OGR?

How to write shape data using OGR-GDAL?
Note that for the “ESRI Shapefile” driver and GDAL >= 1.9, the layer_options value of ‘ENCODING=“LDID/CP1252”’ or other values found on http://www.autopark.ru/ASBProgrammerGuide/DBFSTRUC.HTM to set the encoding byte of the output DBF file (link refered to in ogr/ogrsf_frmts/shape/ogrshapelayer.cpp.
