24.2.1.1. Dataset Identification 

Reports the name of GDAL drivers that can open files contained in a folder, with optional additional details, and write the result into an output vector layer.

Attention

Running this algorithm requires QGIS installed with GDAL >= 3.13.0 (see Help ► About menu).

Parameters

Label	Name	Type	Description
Input folder	`INPUT`	[folder]	Folder containing datasets to identify.
Perform recursive exploration of the input folder	`RECURSIVE`	[boolean] Default: `True`	If checked, the algorithm will scan subfolders recursively to identify datasets in the entire directory tree.
Add details about identified datasets in the output	`DETAILS`	[boolean] Default: `True`	If checked, additional details about each identified dataset will be added to the output vector layer.
Output file	`OUTPUT`	[vector: any] Default: `[Save to temporary file]`	Specification of the output vector layer. One of: Save to a Temporary File Save to File…

Description

Output file

OUTPUT

[vector: any]

Vector layer containing the identification fields:

filename: name of the file.
driver: name of the GDAL driver that can open the file.
Additional fields if the Add details about identified datasets in the output option is checked:
- layout: specifies the internal layout of the dataset, indicating how and where the different components of a TIFF file are stored. Currently, the only supported value (when set) is COG (Cloud Optimized GeoTIFF).
- file_list: side-car files (files that store extra data) associated with the dataset.
- has_crs: whether the dataset has a coordinate reference system defined.
- has_geotransform: whether the dataset defines a geotransform that maps image (pixel–line) coordinates to georeferenced coordinates (projected or geographic coordinates).
- has_overview: whether the dataset has overview.
