Although this is not the answer you are looking for. I will point you to the website: http://linesearch.org/ If you are doing any work especially involving a digger then you register at that site and do a an enquiry with location and if it is in the vicinity of any above or under ground plant from various operators such as National Grid Electric Transmission then you (and they) are alerted and one sends off details of works and recieves maps back. Unfortunately all the asset details of such utilities in Great Britain are referenced against Ordance Survey Mastermap often transitioned from OS Landline and before that large scale 1:1250 or 1:500 paper OS maps. And so I believe OS will consider them derivitive works and unable to incorporate into OSM. > What is he etiquette for asking a utility/authority departments for > information? Would it carry more weight if one the originators of OSM > did the deed? All utilties will have an asset records department. I would be curious to see what response you would get. I am guessing it would take a while for them to repond and maybe a be of back and forth to get any decent reponse if any at all. National Grid UK Electric Transmission's postal address is: National Grid House Warwick Technology Park Gallows Hill Warwick CV34 6DA Telephone: +44 (0) 1926 65 3000 http://www.nationalgrid.com/corporate/About+Us/Contact+Us/departments/T.htm Various bodies have looked at increasing ease of access to infomation on the location of various underground assets: http://www.nuag.co.uk/docs/publicNUAGreportfinal.pdf http://www.nuag.co.uk/ Also see: http://www.mappingtheunderworld.ac.uk/ http://www.vistadtiproject.org/ http://www.comp.leeds.ac.uk/mtu/vista.htm Articles covering development in recording location of underground pipes (different write-ups of the same project): http://www.ordnancesurvey.co.uk/oswebsite/business/sectors/utilities/docs/as- laid-and-abandoned-gas-pipeline-surveys.pdf http://www.pi-ukchina.org.cn/cfiles/VideoUK/CESNov2007.pdf http://www.geoconnexion.com/uploads/easingpressure_ukv5i4.pdf http://www.korecgroup.com/files/downloads_file-97.pdf If there is an increased use of GPS then perhaps a sharing of raw GPS data could happen but I can not really see a way this would become a priority within the structures and flows of such large companies. And how one could persuade those who can affect the changes required given all other immediate pressures on them of just running their operations. It seems the new commerical upstart rival to OS for large scale mapping http://theukmap.co.uk/ won't make as much claims on derviitve works as OS. So if utilties start using it as an alternative they could more likely open their asset records systems to wider public access. And maybe the utility data could be imported into OSM with just the utilities permission. It remains to be seen what effect TheUKMap as a rivial to OS will be but if adopted by various local authroities and organisations that collect data that is geo refferanced then data that is collected and refferanced against TheUKMap as against OS could then be released more easily. It seems that 'a UK utility tendered for a new mapping product, with the idea of replacing their existing map base within their asset management system. This was for a large area - tens of thousands of square kilometres of urban and rural England. The level of mapping detail required was consistent with what they already had for their urban areas but included more detail in the countryside. They also wanted a range of features not available on the standard products. In the end the project did not proceed, due in no small part to the business risk the utility would be facing if they embarked on creating a new mapping base from scratch. ' Page 6-7: http://theukmap.co.uk/resources/magazine/2009.pdf In order to make a dent in the commercial market for large scale mapping dominated by OS TheUKMap need to differentiate itself as much as possible and the enabling of it's customers to release data they collect after adopting it to share with OSM and others would be one of those point that would bring good will to it and encourage it's adoption. As moment Geospatial Vision Ltd.are recording various bits of street furnature such as lamposts refferanced against OS Mastermap for various local authorities but maybe the local would release this data to us if they used TheUkMap. I hope I have understood the licensing the TheUKMap will use but seems that anything that does not follow exactly the features they have in the map can be shared. "The big difference with UKMap is the right granted to the licensed user to own any derived data they create using UKMap as a base or reference. To qualify as derived data the features cannot already be part of UKMap and features must not be a duplicate in whole or part of any UKMap feature. For example a boundary around an area to define an accident hotspot would be classed as derived data, but a selection of the centre points of all the houses within that boundary would not" from: http://www.theukmap.co.uk/resources/faq/ regards, Micah I have cc:ed this to talk-gb and prob best for any follow thread on the developments I mention above to be on there rather than newbies list. -- http://blog.j12.org/ -- _______________________________________________ newbies mailing list [email protected] http://lists.openstreetmap.org/listinfo/newbies
