Absolute accuracy is based on geographic coordinates.
M Media - the physical devices used to record, store, or transmit data, ie. A large-volume customer may receive similar volumes of gas as a distribution center, and includes factories, power plants, and institutional users of gas. Pipeline corridors pose a cartographic challenge, and NPMS handles them differently on hard-copy and digital maps. On hard-copy maps, a single line with multiple annotations may represent pipeline corridors. In digital files, multiple lines are required, and operators should separate them into individual layers or files Pipeline Crossing - a point where two or more pipelines cross, but where there is no physical connection between the pipelines.
