Determine where the main gas pipelines come from and to where.

Gas pipelines run from gas fields to places of final gas consumption.
If we talk about Russian gas pipelines, then the picture will be something like this: the largest fields are located in the north of the country, and the main consumers, in addition to domestic ones, are in Europe. Thus, the largest branches of gas pipelines originate in the Yamal fields and stretch across the country to the western borders, where they are sent to European countries along several pipelines (Nord Stream 1 and 2 and through Ukraine). In addition, the construction of the South Stream and the construction of a gas pipeline in the Far East are currently underway.
