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.

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.

BJ

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.

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.

PS: There is however still room for a large mapping party in Sydney to
collect street names :-)

[talk-au] Australia licence change redaction recovery..

2013-05-25 Thread Ian Sergeant
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!
