The reasons why gas pipeline coverage in OSM is lacking are:
(1) With very few exceptions, we only map what we can verify on the ground. We don’t map a gas pipeline that we cannot see just because it is supposed to be there according to some other pipeline map (even if that pipeline map was not copyrighted). Now gas pipelines tend to be accompanied by overground tell-tale signs that can be surveyed but it takes some expert knowledge to do that.
(2) OSM does occasionally get complaints and sometimes even legal threats from operators of distribution networks because they believe that their infrastructure is critical for public safety and hence access to this information must be controlled. For example, we had deletion requests from a number of German public utilities regarding our mapping of hydrants, as well as legal threats from a Dutch operator of an oil pipeline.
Thank you for your fast response. I am not suggesting to map gas pipelines only based on other (open source) maps, because the existing open source maps have a lack of accuracy. However, they could assist in the finding of pipeline marker, compressor stations and LNG terminals and could also be used to clean up some of the existing data and metadata.
This would be very helpful for our project.
I am very interested in the background of gas pipeline mapping in OSM, for example:
What was the methodology for the current gas pipeline data in OSM?
I would also be interested, why the Spanish gas pipeline data are nearly complete
whereas the German data are not?
Have you ever heard from a case where there were also legal complains associated with the transport network?
We are currently working on a satellite based method to identify the exact positions of gas transport pipelines and will probably release the data-set under an open source license in about a year. What would be the legal constraints for you to implement such a data set and are there any other concerns?
