Hi,
On a related issue, we've had a number of researchers interested in GIS
layers showing gas pipelines? Gas pipeline data perhaps became hard to
get after 9/11 (I think some stuff that was available online was taken
offline after that). These people are interested not only in the big
trunk pipelines, but in the little collection and distribution pipelines.
We purchased some NC statewide data that is strangely scattershot. It
seems very detailed in Charlotte and Greensboro areas (immediately off
the big Transco pipeline), but pretty sparse in many other areas
including around here, although they probably have natural gas going to
all counties in the state. This data is from PennWell (MapSearch). I'm
guessing that they have lines from some companies and not others.
Purchasing these for the entire country would be quite expensive, and
I'm not sure how complete it is.
The state of NC has some layers derived from old mid-1990s USGS Digital
Line Graph files, which in turn derived from digitized USGS 1:24,000 or
1:100,000 topographic paper maps.
http://data.nconemap.com/geoportal/catalog/main/home.page There are
lines all over the place, but they certainly don't connect up into a
coherent network (each quadrangle of the paper maps is from a different
date, the pipelines may not be shown in built-up areas, etc.). We have
the DLG data available nationally on CD, but the quality of the
networking seems to be scattershot to the point of having very limited
usefulness.
Also, it's available in tiles representing the paper quadrangle sheets,
so it would be a big project to piece together a GIS layer covering a
large area (the state of NC did this, but and I'd be interested of other
such merged layers. If I remember, it's a bit tedious to extract the
data from the DLG's to use in ArcGIS, and the attributes are poor to
non-existent.
Thanks,
Mark
