Re: [talk-au] Australia licence change redaction recovery..
Yes thanks to all. Great to see the connecting roads reinstated and the routing largely back in action. Still a lot of minor roads missing with weird nodes scattered around but no great problem cleaning up. As more a bushwalker I mainly concentrate on tracks and geographical features but wonderful that the road infrastructure is nearly always there to connect into.

Re: [talk-au] Australia licence change redaction recovery..
Ian, Thanks very much for doing this exercise. I agree with all the sentiments already expressed - it's so encouraging to see we bounced back so fast, and so strong, and that all our efforts have made a difference. Everyone in the project should feel very proud of what we achieved.

Thanks very much for doing this - I've been quite curious about where we're up to. I had guessed we were about on par - so this is good news. I've been doing a fair bit of aerial mapping lately - not sure whether remapping or not. I tend to be pretty conservative with road classifications on a first pass. Later, I might look at the area and upgrade a couple of the roads. Steve ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
Re: [talk-au] Australia licence change redaction recovery..
Ian, thanks for the interesting data. I believe we are all somewhat relieved that we are recovering from the redaction process relatively fast, if not faster than expected.

[talk-au] Australia licence change redaction recovery..
I crunched some numbers comparing AU planet extracts from today and prior to the redaction commencing. Although they were for my personal edification, I thought I'd share them. We have about 70,000 km of additional mapped unclassified and residential road now than we did before the redaction process - that is an increase in distance of about 27%. In terms of distance of named roads in this category, we're about where we were before the redaction in absolute terms. Trunk and motorways there is no significant variation. The number of kilometres of mapped road and named roads in this category is roughly unchanged. In primary, secondary, and tertiary, we've had an increase in mapped distance of 35,000km, or around 20%. Although we've seen a significant decrease in the number of secondary roads, and marked increase in the mapped km of tertiary roads. Our post-redaction remappers have a tendency towards tertiary roads, it would seem. Our length of named roads in this category is up in actual kilometres, but down on a relative basis. In paths, tracks, footways and cycleways and service roads our mapped distance is also up, We've seen huge increases in mapped tracks - closing on double what we had before. So, my summary would be that we've probably comprehensively remapped he motorways and trunk roads across the country. We've got significantly more tracks, paths and residential/unclassified roads than we had before. There would seem to be artifacts of extensive aerial remapping, with the lower percentage overall of named roads, and what I'm thinking could be a consequent tendency to underrate what passes for a secondary road in Australia. I'd also attribute greater mapping outside of urban areas to the more extensive bing imagery coverage, and possibly the focus of the redaction process on urban areas. Of course, this is all quantitative data, not qualitative. Take it for what it is. My summary is just a guess, and I can't say with any certainty that the increase in distance isn't just fence posts on the Kimberley!
