Functions

_run_chunk(→ None)

atm_interpolation(→ None)

Perform an empirical line interpolation and gaussian smoothing to atmospheric parameters.

Module Contents

_run_chunk(start_line: int, stop_line: int, reference_state_file: str, reference_locations_file: str, input_locations_file: str, segmentation_file: str, output_atm_file: str, atm_band_names: list, nneighbors: list, nodata_value: float, loglevel: str, logfile: str) → None[source]
Parameters:

  • start_line – line to start empirical line run at

  • stop_line – line to stop empirical line run at

  • reference_state_file – source file for retrieved superpixel state

  • reference_locations_file – source file for file locations (lon, lat, elev), (interpolation built from this)

  • input_locations_file – input location file (interpolate over this)

  • segmentation_file – input file noting the per-pixel segmentation used

  • output_atm_file – output file for interpolated and smoothed per pixel atmospheric state

  • atm_band_names – names of atmospheric state parameters

  • nneighbors – number of neighbors to use for interpolation

  • nodata_value – nodata value of input and output

  • loglevel – logging level

  • logfile – logging file

Returns:

None
