remotior_sensus.tools.band_resample module

Band resample.

This tool allows for resampling and reprojecting bands.

Typical usage example:

>>> # import Remotior Sensus and start the session
>>> import remotior_sensus
>>> rs = remotior_sensus.Session()
>>> # start the process
>>> rs.band_resample(input_bands=['path_1', 'path_2'],
... output_path='output_path')
remotior_sensus.tools.band_resample.band_resample(input_bands: list | int | BandSet, output_path: None | str = None, epsg_code: None | str = None, align_raster: str | BandSet | int | None = None, overwrite: bool | None = False, resampling: None | str = None, nodata_value: None | int = None, x_y_resolution: list | int | None = None, resample_pixel_factor: None | float = None, output_data_type: None | str = None, same_extent: bool | None = False, virtual_output: bool | None = None, compress=None, compress_format=None, prefix: str | None = '', extent_list: list | None = None, n_processes: None | int = None, available_ram: None | int = None, bandset_catalog: BandSetCatalog | None = None)

Performs band resample and reprojection.

This tool performs the resampling and reprojection of raster bands. Available resampling methods are:

  • nearest_neighbour

  • average

  • sum

  • maximum

  • minimum

  • mode

  • median

  • first_quartile

  • third_quartile

Parameters:

  • input_bands – input of type BandSet or list of paths or integer number of BandSet.

  • output_path – string of output path directory or list of paths.

  • epsg_code – optional EPSG code for output.

  • align_raster – string path of raster used for aligning output pixels and projections.

  • overwrite – if True, output overwrites existing files.

  • resampling – method of resample such as nearest_neighbour (default), average, sum, maximum, minimum, mode, median, first_quartile, third_quartile.

  • nodata_value – value to be considered as nodata.

  • x_y_resolution – integer pixel size of output raster or pixel size as list of x, y.

  • resample_pixel_factor – define output resolution by multiplying original pixel size to this value.

  • output_data_type – optional raster output data type, if None the data type is the same as input raster.

  • same_extent – if True, output extent is the same as align_raster.

  • virtual_output – if True (and output_path is directory), save output as virtual raster of multiprocess parts.

  • prefix – optional string for output name prefix.

  • extent_list – list of boundary coordinates left top right bottom.

  • compress – if True, compress output.

  • compress_format – format of compressions such as LZW or DEFLATE.

  • n_processes – number of parallel processes.

  • available_ram – number of megabytes of RAM available to processes.

  • bandset_catalog – optional type BandSetCatalog for BandSet number.

Returns:

Object OutputManager() with

  • paths = output list

Examples

Perform the band resample
>>> band_resample(input_bands=['path_1', 'path_2'],
... output_path='output_path', resampling='mode',
... resample_pixel_factor=2)
