wolfhece.wolf_vrt.create_vrt(wdir: str, fout: str = 'out.vrt', format: str = 'tif')

Agglomération de tous les fichiers .tif dans un layer virtuel .vrt

Parameters:

• wdir (str) – working directory

• fout (str) – output file

• format (str) – format of the files to process

wolfhece.wolf_vrt._get_diverged_relative_path(path: pathlib.Path, base: pathlib.Path) → pathlib.Path

Get relative path from base to path, even if they only share part of their paths. More general than the next function “_get_relative_path”, especially for not “child/parents paths”

wolfhece.wolf_vrt._get_relative_path(path: pathlib.Path, base: pathlib.Path)

Get relative path from base to path

Parameters:

• path (Path) – path to get relative path

• base (Path) – base path

wolfhece.wolf_vrt.create_vrt_from_files(files: list[pathlib.Path] = [], fout: pathlib.Path = 'assembly.vrt')

Agglomération de tous les fichiers énumérés dans files dans un layer virtuel .vrt

Parameters:

• files (list[Path]) – list of files to process

• fout (Path) – output file

wolfhece.wolf_vrt.create_vrt_from_files_first_based(files: list[pathlib.Path] = [], fout: pathlib.Path = 'assembly.vrt', Nodata: float = 99999.0)

Agglomération de tous les fichiers énumérés dans files dans un layer virtuel .vrt

Restreint l’emprise et force la résolution sur le premier fichier listé

wolfhece.wolf_vrt.create_vrt_from_diverged_files(files: list[pathlib.Path] = [], fout: pathlib.Path = 'assembly.vrt')

Agglomération de tous les fichiers énumérés dans files dans un layer virtuel .vrt

Parameters:

• files (list[Path]) – list of files to process

• fout (Path) – output file

wolfhece.wolf_vrt.create_vrt_from_diverged_files_first_based(files: list[pathlib.Path] = [], fout: pathlib.Path = 'assembly.vrt', Nodata: float = 99999.0)

Agglomération de tous les fichiers énumérés dans files dans un layer virtuel .vrt

Restreint l’emprise et force la résolution sur le premier fichier listé

wolfhece.wolf_vrt.translate_vrt2tif(fn: str, fout: str = None)

Translate vrt file to tif file

Parameters:

• fn – (str) ‘.vrt’ file to translate

• fout – (str, optional) ‘.tif’ file out. Defaults to None –> fn+’.tif’

wolfhece.wolf_vrt.crop_vrt(fn: str, crop: list, fout: str = None)

Crop vrt file

Parameters:

• fn (str) – (str) ‘.vrt’ file to crop

• crop (list) – (list) Bounds [[xmin, xmax], [ymin,ymax]] aka [[xLL, xUR], [yLL,yUR]]

• fout (str) – (str, optional) ‘.tif’ file out. Defaults to None –> fn+’_crop.tif’

wolfhece.wolf_vrt.create_contours(files: list[pathlib.Path] = [], fout: pathlib.Path = 'assembly.vec', color_exterior: tuple = (255, 0, 0), color_interior: tuple = (0, 0, 255), width: int = 3, ignore_first: bool = True, create_extern: bool = True, create_intern: bool = True, force_mask_border: bool = True) → wolfhece.PyVertexvectors.Zones

Create contour/footprint from files

Parameters:

• files (list[Path]) – list of files to process

• fout (Path - if None, no output file) – output file

• color_exterior (tuple) – RGB color for exterior contour

• color_interior (tuple) – RGB color for interior contour

• width (int) – width of the contour

• ignore_first (bool) – ignore the first file in the list

• create_extern (bool) – create exterior contour

• create_intern (bool) – create interior contour

• force_mask_border (bool) – force masked data along borders – [0,:], [-1,:], [:,0], [:,-1
