Air Liquide keeps its pipelines in order

The transport of gases via pipelines is no sinecure. the area around a pipeline must be free of trees and other structures to prevent breakages. But how do you manage more than 2225 kilometers of pipeline? Location data are the key.

Challenge

By law and internal Air Liquide rules, for safety reasons, it is forbidden to have trees or other structures in the area around a pipeline. It is therefore important that the zone around the pipes of Air Liquide is charted.

Solution

Geo Solutions (Bits of Data) came up with a solution to make an inventory of the pipeline environment. The object-based land cover classification uses recent aerial photographs, elevation data and existing topographic datasets. The classification consists of several steps, which is translated into a custom-made classification tree. The classification is mainly based on infrared aerial photographs in combination with altitude information (derived from LiDAR data) to separate high from low vegetation.

Result

Structures and vegetation near the pipeline are classified. An additional GIS analysis maps, among other things, the accessibility of the trees that have to be cut. Other potential impacts on the pipeline are also identified, such as waterways, roads and railways.

An overview of all trees and structures in a perimeter around the pipelines of Air Liquide allows you to immediately intervene where necessary.
