Writeogr r

See writeValues for writing in chunks e. If other cases the default format is used. The default format is 'raster', but this setting can be changed see rasterOptions. Output file type. See writeFormats.

If this argument is not provided, it is attempted to infer it from the filename extension. If that fails, the default format is used. The default format is 'raster', but this can be changed using rasterOptions. Additional arguments: datatype Character.

Output data type e. See dataType. If no datatype is specified, 'FLT4S' is used, unless this default value was changed with rasterOptions overwrite : Logical. Set a value to show a progress bar. Valid values are "text" and "window". NAflag : Numeric. To overwrite the default value used to represent NA in a file bandorder : Character.

For 'native' file formats only. For some other formats you can use the 'options' argument see below options : Character. File format specific GDAL options. This can be useful when writing files to be read by applications intolerant of unrecognised tags. NetCDF files have the following additional, optional, arguments: varnamevarunitlongnamexnameynameznamezunit. If TRUEthe crs is written to a. This can be useful when writing to an ascii file or another file type that does not store the crs.

You can provide a vector of filenames that matches the number of layers. Or you can provide a single filename that will get a unique suffix see below. Some of these formats can be used with or without rgdal idrisi, SAGA, ascii. You need the 'ncdf4' library for the 'CDF' format. In multi-layer files i. Note that bandorder is not the same as filetype here.

Put your R skills to the test Start Now.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.

Working out which combination of dsn, layer, and driver and option values give the desired output takes time and care, and is constrained by the ability of drivers to write output; many are read-only.

Users are advised to explore this on a case to case basis using Encoding on string fields of objects to be output, converting where necessary with iconv or assigning the appropriate value with Encoding.

writeRaster

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. Classes c "factor", "POSIXt" are converted to character strings, and c "logical" to integer internally. They should never be used by anyone who is not confident about deleting files.

In fixing a bug in the correct handling of SFS polygon geometries in version 1. 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. Version 1.The function reads an OGR data source and layer into a suitable Spatial vector object.

It can only handle layers with conformable geometry features not mixtures of points, lines, or polygons in a single layer. It will set the spatial reference system if the layer has such metadata. For example to read bounds. The logic behind this is that typically one keeps all the shapefiles for a project in one folder directory.

From rgdal 1.

From 1. As R has no such storage mode, three options are offered, analogous with type. The use of bit integers is usually a misunderstanding, as such data is almost always a long key ID. The bases for this implementation are taken from functions in Barry Rowlingson's draft Rmap package, and from Radim Blazek's v.

Please note that the OGR drivers used may not handle missing data gracefully, and be prepared to have to correct for this manually.

From rgdal 0. In addition, from 0. An attempt is made to close unclosed rings in polygon geometries. From 0. Apparently features deleted in Qgis are only marked as deleted, but are still in the layer. These are not NULL geometries, but still need to be handled.

Such deleted features were seen as NULL in 0. Users are advised to explore this on a case to case basis using Encoding on string fields of input objects.

Because some drivers support reading string, integer and real list fields, support has been introduced into ogrInfo from version 0. This may lead to the introduction of the -splitlistfields facility from the command line utility ogrinfo. In addition, ogrInfo reports that there are no features when counting FIDs in a while loop over features in ogrFIDs never enters the loop, despite the layer feature count reporting at least one feature.

I'd like to use writeOGR inside a loop to save shapefiles to folders. I'm having trouble figuring out how the name is used to save the actual file. I'd like writeOGR to save each resulting shapefile in a separate folder, with the name of the file.

Still a lot to learn about the gdal package. At the expense of kittens, as it was a requirement.
