osgeo.gdal.SuggestedWarpOutput(*args)

Suggest output dataset size and extent.

SuggestedWarpOutput(src: Dataset, transformer: Transformer) -> SuggestedWarpOutputRes SuggestedWarpOutput(src: Dataset, options: list[str]) -> SuggestedWarpOutputRes

This function is used to suggest the size, and georeferenced extents appropriate given the indicated transformation and input file. It walks the edges of the input file (approximately 20 sample points along each edge) transforming into output coordinates in order to get an extents box.

Then a resolution is computed with the intent that the length of the distance from the top left corner of the output imagery to the bottom right corner would represent the same number of pixels as in the source image. Note that if the image is somewhat rotated the diagonal taken isn't of the whole output bounding rectangle, but instead of the locations where the top/left and bottom/right corners transform. The output pixel size is always square. This is intended to approximately preserve the resolution of the input data in the output file.

There are 2 forms of this method:

  • one that takes the output of gdal.Transformer(src, dst, options) as the second argument. The src argument of the gdal.Transformer() call should nominally be the src argument passed to this function. The dst argument of the gdal.Transformer() call should nominally be None The third argument of the gdal.Transformer() call should be a list of strings, that are transforming options accepted by GDALCreateGenImgProjTransformer2() (e.g DST_SRS)

  • one that takes a list of strings as the second argument. Those strings are the transforming options accepted by GDALCreateGenImgProjTransformer2() (e.g DST_SRS)

Parameters:
  • src (Dataset) -- Source dataset

  • transformer (Transformer) -- The return value of gdal.Transformer(src, None, options) (exclusive with below options parameter)

  • options (list[str]) -- List of strings that are the transforming options accepted by GDALCreateGenImgProjTransformer2() (e.g DST_SRS) (exclusive with above transformer parameter)

Returns:

  • A SuggestedWarpOutputRes class instance with the following members

  • - width (number of pixels in width of the output dataset)

  • - height (number of pixels in height of the output dataset)

  • - xmin (minimum value of the georeferenced X coordinates)

  • - ymin (maximum value of the georeferenced Y coordinates)

  • - xmax (minimum value of the georeferenced X coordinates)

  • - ymax (maximum value of the georeferenced Y coordinates)

  • datasetCreationOptions -- list or dict of dataset creation options

  • layerCreationOptions -- list or dict of layer creation options

  • layers -- list of layers to convert

  • layerName -- output layer name

  • geometryType -- output layer geometry type ('POINT', ....). May be an array of strings when using a special value like 'PROMOTE_TO_MULTI', 'CONVERT_TO_LINEAR', 'CONVERT_TO_CURVE' combined with another one or a geometry type.

  • dim -- output dimension ('XY', 'XYZ', 'XYM', 'XYZM', 'layer_dim')

  • transactionSize -- number of features to save per transaction (default 100 000). Increase the value for better performance when writing into DBMS drivers that have transaction support. Set to "unlimited" to load the data into a single transaction.

  • clipSrc -- clip geometries to the specified bounding box (expressed in source SRS), WKT geometry (POLYGON or MULTIPOLYGON), from a datasource or to the spatial extent of the -spat option if you use the "spat_extent" keyword. When specifying a datasource, you will generally want to use it in combination with the clipSrcLayer, clipSrcWhere or clipSrcSQL options.

  • clipSrcSQL -- select desired geometries using an SQL query instead.

  • clipSrcLayer -- select the named layer from the source clip datasource.

  • clipSrcWhere -- restrict desired geometries based on attribute query.

  • clipDst -- clip geometries after reprojection to the specified bounding box (expressed in dest SRS), WKT geometry (POLYGON or MULTIPOLYGON) or from a datasource. When specifying a datasource, you will generally want to use it in combination of the clipDstLayer, clipDstWhere or clipDstSQL options.

  • clipDstSQL -- select desired geometries using an SQL query instead.

  • clipDstLayer -- select the named layer from the destination clip datasource.

  • clipDstWhere -- restrict desired geometries based on attribute query.

  • simplifyTolerance -- distance tolerance for simplification. The algorithm used preserves topology per feature, in particular for polygon geometries, but not for a whole layer.

  • segmentizeMaxDist -- maximum distance between consecutive nodes of a line geometry

  • makeValid -- run MakeValid() on geometries

  • mapFieldType -- converts any field of the specified type to another type. Valid types are: Integer, Integer64, Real, String, Date, Time, DateTime, Binary, IntegerList, Integer64List, RealList, StringList. Types can also include subtype between parenthesis, such as Integer(Boolean), Real(Float32),... Special value All can be used to convert all fields to another type. This is an alternate way to using the CAST operator of OGR SQL, that may avoid typing a long SQL query. Note that this does not influence the field types used by the source driver, and is only an afterwards conversion.

  • explodeCollections -- produce one feature for each geometry in any kind of geometry collection in the source file, applied after any -sql option. This option is not compatible with preserveFID but a SQLStatement (e.g. SELECT fid AS original_fid, * FROM ...) can be used to store the original FID if needed.

  • preserveFID -- Use the FID of the source features instead of letting the output driver automatically assign a new one (for formats that require a FID). If not in append mode, this behavior is the default if the output driver has a FID layer creation option, in which case the name of the source FID column will be used and source feature IDs will be attempted to be preserved. This behavior can be disabled by setting -unsetFid. This option is not compatible with explodeCollections

  • zField -- name of field to use to set the Z component of geometries

  • resolveDomains -- whether to create an additional field for each field associated with a coded field domain.

  • skipFailures -- whether to skip failures

  • limit -- maximum number of features to read per layer

  • xyRes -- Geometry X,Y coordinate resolution. Numeric value, or numeric value suffixed with " m", " mm" or "deg".

  • zRes -- Geometry Z coordinate resolution. Numeric value, or numeric value suffixed with " m" or " mm".

  • mRes -- Geometry M coordinate resolution. Numeric value.

  • setCoordPrecision -- Set to False to unset the geometry coordinate precision.

  • callback -- callback method

  • callback_data -- user data for callback
