GeoLibre License: Which Open-Source License Does the GeoLibre Project Use?

The GeoLibre project is released under the MIT License, a permissive open-source license that allows commercial use, modification, distribution, and private use with minimal restrictions.

GeoLibre is a geospatial data processing library maintained by the opengeos organization. Understanding its licensing terms is essential for developers integrating the library into commercial products, academic research, or derivative open-source projects. The MIT License is declared consistently across the repository's configuration files and the canonical license text resides in the root-level LICENSE file.

Where the MIT License Is Declared in GeoLibre

The GeoLibre project follows standard open-source conventions by placing license information in multiple locations for discoverability.

Root-Level LICENSE File

The authoritative license text lives at the repository root:

https://github.com/opengeos/GeoLibre/blob/main/LICENSE

This file contains the full MIT License text, including the copyright notice and permission grant. When redistributing GeoLibre or creating derivative works, this file must be included to comply with license terms.

Python Package Configuration

The Python implementation explicitly declares the license in its build configuration. In python/pyproject.toml, the metadata includes:

license = "MIT"

This declaration ensures that package managers like pip and PyPI correctly index GeoLibre's licensing terms. Tools that audit dependencies for license compliance will automatically detect this field.

JavaScript/TypeScript Package Manifests

GeoLibre's monorepo structure includes multiple npm workspaces, each with its own package.json. These files consistently specify the MIT License. For example, apps/geolibre-desktop/package.json includes:

{
  "license": "MIT"
}

This pattern repeats across workspace packages, ensuring uniform licensing regardless of which specific GeoLibre module you install via npm or yarn.

How to Programmatically Read the GeoLibre License

While the license itself isn't executable code, you may need to display or validate license information in applications that depend on GeoLibre.

Reading the License in Node.js

Use the fs module to load the license text from the repository structure:

import { readFileSync } from 'fs';
import { join } from 'path';

const licensePath = join(import.meta.dirname, '..', '..', 'LICENSE');
const licenseText = readFileSync(licensePath, 'utf8');

console.log('GeoLibre License:\n', licenseText);

This approach works when GeoLibre is installed as a dependency where the LICENSE file is preserved in the package distribution.

Reading the License in Python

Use importlib.resources to access bundled license files within the installed package:

import importlib.resources as pkg_resources

license_text = pkg_resources.read_text('geolibre', 'LICENSE')
print('GeoLibre License:\n', license_text)

Note: This requires that the LICENSE file is included in the package's MANIFEST.in or pyproject.toml include directives to be present in the installed distribution.

What the MIT License Permits for GeoLibre Users

The MIT License grants four primary freedoms with minimal obligations:

1. Commercial use — You may use GeoLibre in proprietary, for-profit applications without paying royalties or licensing fees.

2. Modification — You can fork, modify, and improve GeoLibre's source code to suit your specific geospatial processing needs.

3. Distribution — You may distribute GeoLibre's original or modified versions as part of larger software packages.

4. Private use — You can use GeoLibre in internal tools without any disclosure requirements.

The sole requirement is preserving the copyright notice and permission notice in all copies or substantial portions of the software.

Key Files Reference

File Path	Purpose
LICENSE	Contains the complete MIT License legal text
python/pyproject.toml	Python package metadata with license = "MIT"
apps/geolibre-desktop/package.json	Example npm workspace license declaration
package.json (root)	Root monorepo license specification

Summary

• GeoLibre uses the MIT License, a permissive open-source license suitable for commercial and academic use.
• The license is declared in LICENSE at the repository root and echoed in python/pyproject.toml and workspace package.json files.
• The MIT License requires only that you preserve the copyright and permission notices when redistributing the code.
• You can programmatically read the license using standard file system APIs in Node.js or importlib.resources in Python.

Frequently Asked Questions

Is GeoLibre free to use in commercial applications?

Yes. The MIT License explicitly permits commercial use without restrictions. You can incorporate GeoLibre into proprietary products, SaaS platforms, or client deliverables without paying licensing fees or open-sourcing your own code. You must only include the original MIT License notice with any distribution of GeoLibre itself.

Do I need to open-source my project if I use GeoLibre?

No. The MIT License does not impose copyleft requirements. Unlike GPL-licensed libraries, GeoLibre can be used in closed-source applications. Your project's source code remains yours to license independently. The only requirement is preserving GeoLibre's license notice in distributions that include the library.

Where can I find the exact license text for GeoLibre?

The canonical license text resides in the repository root at LICENSE. For the Python package specifically, the license is also declared as metadata in python/pyproject.toml. Both sources confirm the MIT License. When installing via pip or npm, the license information is also available through package metadata queries (e.g., pip show geolibre or npm info geolibre).
