Description
The map contains the 633.54km 48″ GZ4 Gas Pipeline, which consists of two sections: 513.17km Hassi R’mel – Arzew section and 120.37km Mactaa Douz – Béni Saf section. The Hassi R’mel – Arzew section runs from the National Gas Dispatching Center (CNDG) in Hassi R’Mel, Laghouat, and ends at Arzew Arrival Terminal in Bethioua, Oran. The Mactaa Douz – Béni Saf section runs from the Mactaa Douz Departure Terminal in Magtaa Douz, Mascara, and ends at Beni Saf Arrival Terminal in Sidi Ben Adda, Ain Témouchent. The pipeline is also known as Hassi R’Mel – Arzew Gas Pipeline.

2 Methodology
The vector pipeline maps (.pdf and .ai) are created using data collected from various sources including GPS, remote sensing technology, and geographic surveys, resulting in more precise location information for pipeline stations and turning points along the pipeline route.
3 Files Included in This Digital Map
3.1 [Main Map] GZ4 Gas Pipeline (Hassi R’Mel – Arzew Gas Pipeline)
This map includes the geographical area from the pipeline’s starting point to its end point. Its content contains the pipeline route, stations along the pipeline, and the administrative regions that the pipeline passes through.
Two file formats, .pdf and .ai (Adobe Illustrator), are included. Both of them are editable and layered. Users can show and hide a layer simply with a mouse click.
The map consists of following independent layers:
- Project Name and Legend
- Names of Main Stations
- Names of Valve Stations
- Names of Water
- Names of Countries
- Names of Wilayas (Provinces)
- Names of Dairas (Districts)
- Main Stations
- Valve Stations
- Pipeline
- Water
- Borders of Countries
- Borders of Wilayas (Provinces)
- Borders of Dairas (Districts)
- Background Color
3.2 Algeria Country Map
The country map itself doesn’t contain pipeline information. However, it serves as a platform into which our users can easily add various pipeline map plugins. With pipeline map plugins, the country map provides a perspective of the pipelines from the geographical scope of the entire nation.![[The Interface] Algeria Country Map](https://i0.wp.com/digital-oil-gas-map.com/wp-content/uploads/2026/04/The-Interface-Algeria-Country-Map.jpg?resize=640%2C400&ssl=1)
The country map is an editable and layered .pdf file. It consists of following independent layers:
- Legend
- Names of Water
- Names of Countries
- Names of Wilayas (Provinces)
- Names of Dairas (Districts)
- Water
- Borders of Countries
- Borders of Wilayas (Provinces)
- Borders of Dairas (Districts)

3.3 [Algeria Country Map Plugin] GZ4 Gas Pipeline (Hassi R’Mel – Arzew Gas Pipeline)
The country map plugin is a single-layered .pdf file containing the pipeline route. It can be added into the country map simply with a couple of mouse clicks. In this way, our users can assemble their own oil and gas pipeline network with other oil and gas pipeline map plugins they purchased. (Tutorial on how to add a pipeline map plugin).
4 Editability of Map:
Based on the layered digital map (.pdf and .ai), users can perform further development and modifications, including but not limited to:
- Adjusting the position of text and modifying its attributes such as font, font size, and color;
- Adjusting the position and size of icon symbols;
- Modifying the path of oil and gas pipelines to reflect changes caused by rerouting;
- Adding new pipelines and stations;
- Changing the border color and line weight of different administrative regions;
- Modifying the map background color.
