GDAL projections¶

Tanım¶

Extracts the projection of a raster file and writes it into a world-file. The algorithm is derived from the the GDAL srsinfo utility .

Parametreler¶

Input file [raster]

input raster file.

Create also .prj file [boolean]

If this is acivated also a *.prj-file containing the projection information is created.

Default: False

Tanım¶

Transfers a raster layer into another Coordinate Reference System (CRS). The output file resolution and the resampling method can be chosen. The algorithm is derived from the GDAL warp utility .

Parametreler¶

Input layer [raster]

Input raster layer.

Source SRS (EPSG Code) [crs]

Defines the CRS of the input raster layer.

Default: EPSG:4326

Destination SRS (EPSG Code) [crs]

Defines the target CRS of the raster layer.

Default: EPSG:4326

Output file resolution in target georeferenced units (leave 0 for no change) [number]

Defines the output file resolution of reprojection result.

Default: 0.0

Resampling method [selection]

Several resampling methods can be chosen for the reprojection. By default a near resampling method is chosen.

Options:

• 0 — near
• 1 — bilinear
• 2 — cubic
• 3 — cubicspline
• 4 — lanczos

Default: 0

Additional creation parameters [string]

Optional.

Default: (not set)

Output raster type [selection]

Defines the format of the output raster file. By default this is Float32.

Options:

• 0 — Byte
• 1 — Int16
• 2 — UInt16
• 3 — UInt32
• 4 — Int32
• 5 — Float32
• 6 — Float64
• 7 — CInt16
• 8 — CInt32
• 9 — CFloat32
• 10 — CFloat64

Default: 5
