# Using TileInfo object

The following script describes how to use the basic methods of TileInfo objects, which are objects meant to store and parse parameters used, paths to files, dates used.

The first step is to import the class function from the module.

from fordead.import_data import TileInfo


Create TileInfo Object using the path of the directory where you want information stored

tile = TileInfo("<data_directory>")


Then use the method to import information if there is already a TileInfo object saved in the directory

tile = tile.import_info()


You can then add parameters used to the object, in the form of a dictionnary.

tile.add_parameters({"parameter1" : value1, "parameter2" : value2})


It can then be retrieved using the parameter's key : tile.parameters["parameter1"], if there is a conflict, for example if "parameter1" was already stored in the TileInfo object with a different value, tile.parameters["Overwrite"] is given the value True.

You can also add paths to the object. If directories and parent directories don't exist, they are created.

tile.add_dirpath("vegetation_index_directory", tile.data_directory / "VegetationIndex") #Adding path to a directory

It can then be retrieved using the path's key : tile.paths["vegetation_index_directory"], tile.parameters["paths"].
tile.delete_dirs("vegetation_index_directory","forest_mask")

Also, to print information stored in the object, simply use tile.print_info(). Printing a TileInfo object information is also possible from the command line using the command fordead read_tileinfo -o <data_directory> (see details).
In the end, every addition and change to the object can be save using tile.save_info().
