Mileage = mapped miles from EIA generalized geometry (parallel loops counted separately); not PHMSA-reported mileage.
Local distribution mains are not in any public dataset (PHMSA NPMS and MARIS publish transmission only), so only transmission lines are shown.
Sawmills: Mississippi Forestry Commission, 2025 MS Forest Products Companies (Forest Industry Directory feature service, edited 2025-07-08). The directory carries no open/closed status; Forisk (Feb 2024) lists open lumber mills in Meridian, Summit, Tylertown, Corinth and Lumberton that MFC omits. Hollow dot = city centroid, no published coordinates.
Receipt/delivery points and compressor stations: HIFLD/EIA Natural Gas Receipt Delivery Points (source 2015, validated 2016-2017) and Compressor Stations (2020), via ArcGIS Online mirror. Receipt = point where gas enters the pipeline; existing points show where third-party gas is already accepted.
