Re: [talk-au] How to make admin boundaries disappear if they aren't duplicated with highway=* etc
For those wanting to de-merge other way information from admin boundaries here's a cheat sheet, firstly setup and test your filter settings, for this purpose I setup 2 filters, one to disable or hide waterways and coastlines even if they are admin boundaries as I see these as harmless compared to other sorts of ways. I also setup a filter to only show admin boundaries with railway or highway tags, as these are the most common that need to be fixed: filter 1: waterway=* | natural=coastline | natural=land filter 2: boundary=administrative -(highway=* | railway=*) type:way You need filters in that order, I also selected the hide option so all the irrelevant boundaries just don't show. Next you can use the XAPI interface to download all the admin boundaries within a given bounding box by opening a location from within JOSM: http://xapi.openstreetmap.org/api/0.6/way%5Bboundary=administrative%5D%5Bbbox=151.7211913998,-28.4638623,153.6273192998,-26.6670958%5D The bbox above is for south east queensland and will download about 33M of OSM data as a result, but the same thing could be used for anywhere. With the filtering in place there should be only a few admin boundaries still being displayed, all you need to do then is copy and paste or duplicate the ways, slightly offset the boundaries and you're done. The XAPI interface is delayed by 5 minutes or so behind the main API server, so it can be worth selecting any/all ways and update them from the main API before editing. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
[talk-au] How to make admin boundaries disappear if they aren't duplicated with highway=* etc
Since JOSM implemented object filtering I've been trying on and off to figure out how to make admin boundaries disappear 99% of the time when they aren't also tagged as highway, waterway, natural, railway or other similar tags, I finally got annoyed enough to email the dev list about this and even then it ultimately took a brief moment of inspiration to finally figure this out. When you go to add a new filter, just paste in the following: boundary=administrative -(highway=* | waterway=* | natural=* | railway=*) type:way If there are other common keys shared with admin boundaries you just add them to the section inside the brackets, from there you can tick the box under the 'H' column (for hide), and from then on the only admin boundaries you will see will be those that are merged with roads etc. If you want to de-merge the roads etc from admin boundaries it's usually a trivial matter of copying the section and pasting it, and then slightly offseting the admin boundary and striping any additional tags and then linking the newly pasted object into the road network or what not. I've also documented this, on the ever growing page of tagging tips: http://wiki.openstreetmap.org/wiki/Australian_Tagging_Guidelines#Hiding_admin_boundaries_in_JOSM ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

This seems interesting, ESRI have launched ArcGIS.com http://www.arcgis.com/home/ which has an online mapping toolset (Microsoft Silverlight plugin required) that allows you to use OpenStreetMap basemaps - I thought this was interesting as it is from a company that until the OSM Haiti remote mapping success hit the news, was perceived (by me), to have refused to acknowledge OpenStreetMap even existed :-) Cool - I do wonder if they are serving the tiles, or useing OSM bandwidth Chris ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
[talk-au] US to spend $8bn upgrading GPS constellation
The United States is about to give the now nearly ubiquitous Global Positioning System an $8 billion overhaul. The improvements, which involve replacing each of the 24 aging GPS satellites, are estimated to take over a decade to complete, and will see the triangulation margin of error decrease from 20 feet to around 3 feet. The move comes as more and more devices, from phones to parking meters, are incorporating GPS units into their design. The L.A. Times estimates that there are over 1 billion GPS receivers that rely on the United State’s. location system. http://www.latimes.com/business/la-fi-gps-20100523,0,3054578.story?page=1 ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
