satpy.readers.core.hrit module

HRIT/LRIT format reader.

This module is the base module for all HRIT-based formats. Here, you will find the common building blocks for hrit reading.

One of the features here is the on-the-fly decompression of hrit files when compressed hrit files are encountered (files finishing with .C_).

class satpy.readers.core.hrit.HRITFileHandler(filename, filename_info, filetype_info, hdr_info)

Bases: BaseFileHandler

HRIT standard format reader.

Initialize the reader.

__init__(filename, filename_info, filetype_info, hdr_info)

Initialize the reader.

_get_hd(hdr_info, verbose=False)

Open the file, read and get the basic file header info and set the mda dictionary.

_get_output_info()

property end_time

Get end time.

get_area_def(dsid)

Get the area definition of the band.

get_area_extent(size, offsets, factors, platform_height)

Get the area extent of the file.

get_dataset(key, info)

Load a dataset.

get_xy_from_linecol(line, col, offsets, factors)

Get the intermediate coordinates from line & col.

Intermediate coordinates are actually the instruments scanning angles.

property observation_end_time

Get observation end time.

property observation_start_time

Get observation start time.

read_band(key, info)

Read the data.

property start_time

Get start time.

class satpy.readers.core.hrit.HRITSegment(filename, mda)

Bases: object

An HRIT segment with data.

Set up the segment.

__init__(filename, mda)

Set up the segment.

_get_input_info()

_is_file_like()

_read_data_from_disk()

_read_data_from_file()

_read_file_like()

read_data()

Read the data.

satpy.readers.core.hrit.decompress_buffer(buffer)

Decompress buffer.

Return type:

bytes

satpy.readers.core.hrit.decompress_file(infile)

Decompress an XRIT data file and return the decompressed buffer.

Return type:

bytes

satpy.readers.core.hrit.get_header_content(fp, header_dtype, count=1)

Return the content of the HRIT header.

satpy.readers.core.hrit.get_header_id(fp)

Return the HRIT header common data.
