INGAA Interactive Gas Transmission Map Application
There's a handy map application on the INGAA website if you need to get a big-picture look at where gas transmission pipelines are in the US, by operator and by pipeline system. Click here to view the interactive map showing the main interstate natural gas transmission pipelines (and a few intrastate) in North America. It allows you to click on individual companies and turn on and off various pipelines to get a clearer view of where certain pipelines run. Unlike the public viewer on the National Pipeline Mapping System (NPMS) this allows you to see the entire pipeline route instead of just one county at a time. Thanks INGAA!
