Re: [talk-au] National borders (was: import of state borders?)

2012/8/31 Ian Sergeant inas66+...@gmail.com Well, I think the baseline is defined here.. http://www.comlaw.gov.au/Details/F2006L00525 I don't think we have any issues using those facts as a source. That looks great, combining this with the coastline should work. The coastline can be

Hi Russell, Welcome aboard. Just my thoughts... For a newbie, you've made some very astute observations about the accuracy of the aerial imagery, so thanks for giving it the degree of thought - because many others just dive in and start tracing without understanding these subtleties. You're

Re: [talk-au] Misaligned streets OSM or Bing wrong? - use survey mark?

The bing imagery is out. As per here: http://wiki.openstreetmap.org/wiki/Bing#Precision you need to align the bing imagery to either gps traces or source=survey or source=nearmap. Nearmap guaranteed that their imagery was within one metre, although there are some areas that are outside

Agree with everything that Ben said. In addition, you may like to check the AGRI imagery. If the Bing and AGRI imagery align exactly, chances are you have well aligned Bing imagery. If the AGRI imagery aligns well with traces, it is easy enough to shift the Bing background to align with AGRI,

Re: [talk-au] Misaligned streets OSM or Bing wrong? - use survey mark?

Thanks everyone for the replies. I have imported over 250 GPX traces from my running log, boy does that slow JOSM down. It seems Bing may be offset but having 100+ traces on some paths it is all just a big wide blob of grey. Still, the blob is offset. I might try and cobble together a tool to
