Pipeline GIS Data Sources
US Geological Survey (USGS)
Satellite imagery and aerial photography data available, most of it for free. Plus data from providers including EROS, Earth Explorer, National Map, and National Atlas.
Multi-Resolution Land Characteristic Consortium (MLRC)
Downloadable data relating to land cover, percent tree canopy, and percent urban imperviousness for the United States. The standard data is only at 30 meter resolution but this is a good resource for operators needing data for large swaths of land.
US Census Bureau
Download Population Estimate data to project where people are moving and the likelihood of increased housing or commercial development in an area.
TIGER/Line Shapefiles – US Census Bureau
Download shapefiles of Block Groups, Census Tracts, Traffic Analysis, and other datasets by state or county. Typically accurate within 5 meters or less.
A clearinghouse of government data with a variety of searching options, including the ability to conduct spatial searches.
Federal Geographic Data Committee (FGDC)
A portal with over 250 spatial data collections that can be searched through a single interface.
National Pipeline Mapping System (NPMS), administered by the Pipeline and Hazardous Materials Safety Administration (PHMSA)
Consists of geospatial data, attribute data, public contact information, and metadata pertaining to the interstate and intrastate gas and hazardous liquid transmission pipelines, liquefied natural gas (LNG) plants, and hazardous liquid breakout tanks jurisdictional to PHMSA. Offers a viewer that can be used by the public to determine locations of pipelines in an area.
City, County, and State Websites
Depending on the initiative of the government body, these sites can contain information ranging from building footprints to demographic data. There are typically also portals to numerous other GIS related websites. Some sample sites include:
Various projects have been undertaken by universities around the country to consolidate GIS data. One excellent example is the Stanford University GIS Department’s website.
Launched as a project under Microsoft, TerraServer offers Digital Orthophoto Quadrangle (DOQ) and Digital Raster Graphics (DRG) from the USGS. The resolution on imagery is fairly good and the system allows you to download a "world file" that enables the GIS to place the data. Note that the instructions on the page say to make sure world File extension is ".jpgw" but you should save it as ".jgw" to place the image in ArcMap.
A free tool that provides animated views of the earth along with the ability to upload pipeline GIS data and related data. The coordinates, elevations, and measurements are approximations only.
ESRI ArcGIS Web Services
Free imagery and map data for non-commercial use from ESRI. This data is very easy to upload into ArcMap from the website.
Another ESRI site that allows users and service providers from all over the world to share GIS data.
Soil Data Mart, National Resources Conservation Service
Locate both tabular and spatial data on soil in the United States.
