Welcome to QGIS Lines Ranking plugin documentation!
Applications
The plugin can be used to rank any linear vector layers. One of the most common cases in which it can be used is river network analysis (mainly - stream ordering):
As can be seen from the image above, in the process of the plugin's execution the attributes are assigned to elements of the vector layer of the river network (and then based on the values of these attributes are visualized).
With this plugin it is possible to analyze any linear vector objects, the structure of which is similar to a river net. For example, roads network, railroad system or any other logistic.
Documentation structure
The official documentation of the plugin is divided into two large parts:
- "How-to guides" and "Use cases" - detailed user documentation and examples of analyses which can be performed
- Theoretical issues - a detailed description of how the algorithms in this plugin work

Our publications
We have written several articles that explain how the plugin works. Feel free investigate such a resources in addition to official documentation:
- Stream Ordering: How And Why a Geo-Scientist Sometimes Needed to Rank Rivers on a Map (eng);
- The Algorithm for Ranking the Segments of the River Network for Geographic Information Analysis Based on Graphs (eng);
- Алгоритм ранжирования сегментов речной сети с использованием графов для геоинформационного анализа (rus)
