AutoGR Toolkit Giancan

Use this command to install AutoGR Toolkit:

winget install --id=Giancan.AutoGRToolkit -e

AutoGR Toolkit is a comprehensive set of tools designed to streamline and enhance the process of image georeferencing. It provides automated solutions for generating ground control points, converting geospatial data, and facilitating photogrammetric workflows.

Key Features:

GGrab: Enables users to capture georeferenced orthophotos or satellite images from accessible WMS servers.
AutoGR-SIFT: Automatically produces ground control points using optimized OpenCV-based image matching algorithms.
GeoRef-Filtering: Reduces the number of generated control points, making them more manageable for subsequent processing.
GeoTiff-Converter: Extracts georeferencing information from GeoTIFF files and generates compatible raster formats with world files.
AutoGR-Photogrammetry: Automates the generation of georeferencing data for photogrammetric 3D models using DEMs, supporting Agisoft Metashape, VSFM, and sfm_georef formats.

Audience & Benefit: Ideal for researchers, GIS professionals, and photogrammetrists who require efficient and precise image georeferencing. The toolkit significantly reduces manual effort and accelerates workflows through automation and integration with industry-standard tools. It is particularly beneficial for those working with large datasets or seeking to automate repetitive tasks in geospatial analysis.

Available as a free software package, the AutoGR Toolkit can be installed via winget, making it accessible for Windows users.

AutoGR-Toolkit

AutoGR-Toolkit is a set of modules to improve, facilitate and speedup the process of images georeferencing.

AutoGR-Toolkit, and the embedded tools (GGrab, AutoGR-SIFT, GeoRef-Filtering, GeoTiff-Converter and AutoGR-Photogrammetry) are distributed for free and can be redistributed (free of charge). This software is provided as-is. Redistribution or reverse engineering is not permitted. It is recommended that users download the toolkit directly from this website and subscribe to the dedicated Google Group page for updates and issues support/features requests.

For operational information and application, please have a look at the included HelpFile. Also check regularly for updates (button available in the top menu of all modules) and patches on our website.

A short description of the AutoGR-Toolkit modules:

GGrab:

Allows you to save a georeferenced orthophoto/satellite image (for personal and research purpose) of the area of interest from freely accessible WMS servers.

GGrab and GeoTiff Converter use the Geospatial Data Abstraction Library (GDAL)

http://www.gdal.org

AutoGR-SIFT:

Automatically produces ground control points for image georeferencing.

It is based on the automatic image matching in Computer Vision (OpenCV with image matching 'contrib non-free' modules, optimized and compiled from sources) as an implementation of the David Lowe's SIFT algorithm (http://www.cs.ubc.ca/~lowe/keypoints).

GeoRef-Filtering:

AutoGR-SIFT usually produces thousands of points in a few seconds and this module lets you reduce this number to a more manageable one.

GeoTiff-Converter:

It extracts geographical information from a geotiff file and it produces a .jpg/.png/.tif with respective worldfile.

AutoGR-Photogrammetry:

Using the global digital terrain model available online or a DEM provided by the user, this tool provides users with the facilities to extract X, Y and Z coordinates for each location in the world. It also allows to generate Agisoft Metashape, VSFM and sfm_georef points for photogrammetric 3D models georeferencing in complete automation.

Thanks to Gribouillis and pyTony from the Daniweb's Python Forum and all beta-testers for their immeasurable support for the creation of some special functions in this software.

IMS-FORTH provided the facilities and technical support to develop and finalize this set of applications.
