Re: [talk-au] import of state borders?

Welcome. When doing so I've noticed that most of the state and territory borders are gone. I could already reconstruct the straight parts from remaining segments and nodes. But the non-straight parts are still missing, so there isn't much left of ACT at the moment, for example. Some work has been put in by some OSMers in the past getting accurate border information, not always from the ABS data. There were borders in OSM prior to any ABS import, which are likely clean and could also be used as an alternative if we can dig them out of a full history file! Does anybody have better recall of this than me? Is there any harm in importing for now, and doing any fixes/replacement required later?

But the non-straight parts are still missing, so there isn't much left of ACT at the moment, for example. Looking for a source for these I came across the data from the Australian Bureau of Statistics which are ODbL-compliant according to [1]. Available is are shapefiles for the electoral boundaries [2] and to my understanding these had previously been used for the state boundaries. So I would suggest to import the missing parts of the boundaries from these datasets again. This wouldn't be an automatic import but include manually combining the data with what's already there. Any thoughts? [2] http://data.gov.au/dataset/commonwealth-electoral-boundaries-archive-2009/ No comment on the import, but I wouldn't use the Electoral boundaries to derive any kind of state boundary. Also since data.gov.au just pulls the data from the various different government agencies, I would suggest getting it straight from the source. http://www.abs.gov.au/AUSSTATS/abs@.nsf/DetailsPage/1270.0.55.001July%202011?OpenDocument You would want the last one listed: State (S/T) ASGS Ed 2011 Digital Boundaries in ESRI Shapefile Format.

They only represent an ABS approximation of the official boundary with the aim of generating statistics on these areas. For most purposes they are good enough representation of the actual boundary for us, especially in lure of a better source, and without any on the ground mapping. I hope this has provided some insight. signature.asc Description: OpenPGP digital signature ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

Another puzzle (tagging wise) is that travelling eastwards on 23 at Fyshwick, Ipswich Street is signed as ALT 23 although you don't really get onto to the real Alt 23 until you turn left into Newcastle Street and finally right, on to Monaro Highway I've left this off the relation for now.

[talk-au] remapping help?
Over here at MapBox we're structuring our remapping priorities right now. Starting with end of August we'll have better tracing capacities again (some folks are going out for vacation). If you can use help with tracing / repairing that can be done remotely, please let me know. We want to help, but want to make sure we're supporting the efforts and priorities of the local community. Also here's a map i made last week of mappers contributing the remapping of Sydney on rebuild.poole.ch. Represented are individual nodes colored according to the user that edited or created them. The user's names are scaled based on how many nodes they edited/created. Let me know if you think visualizations like these could be useful in (re)mapping, or could be improved in order to be useful. http://tiles.mapbox.com/villeda/map/map-m7isafy8 Thanks, -ian https://twitter.com/ian_villeda http://www.openstreetmap.org/user/ian29/___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
