License & Legal
Relevant source files
The following files were used as context for generating this wiki page:
The geo-path-reducer project is a JavaScript utility designed to simplify geospatial paths using the Douglas-Peucker algorithm. This document outlines the licensing framework, authorship, and technical identifiers that define the legal standing of the software package.
The project is structured as a modular library that calculates distances between geographical points and reduces path complexity based on an epsilon threshold. The legal and metadata definitions are primarily managed through the project configuration files.
Software License
The geo-path-reducer project is distributed under the MIT License. This is a permissive license that allows users to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software.

Licensing in Project Structure
The license is declared in multiple locations to ensure visibility for both human users and automated package managers:
- Project Metadata: Defined in the
package.jsonfile to inform thenpmecosystem. - Documentation: Explicitly stated in the
README.mdfile, which references aLICENSEfile for full details.
The following diagram illustrates how the license and package identity are integrated into the project's architecture:

Technical Governance and Compliance
The project's legal usage is also influenced by its technical implementation, specifically how it handles geospatial data. The software utilizes specific mathematical models for calculating great-circle distances and perpendicular offsets, which are essential for the algorithm's accuracy.
Functional Dependencies
The software implements the Douglas-Peucker algorithm through a chain of internal modules. While the legal license covers the entire package, the internal logic is divided as follows:
- Simplification Logic: The primary entry point for path reduction.
- Geospatial Math: Calculation of distances using the Earth's radius (6371 km).
- Geometric Analysis: Calculation of perpendicular distances from points to lines.
The diagram represents the internal dependency flow used to process spatial data under the MIT license.
