It looks like there is some datasets that would be useful

* QLD property boundaries
* world heritage listing areas (tourism POIs?)
* BBQ, public toilet and park/playground locations in the ACT
* school locations in the ACT might be useful for landuse/POIs and/or
building outlines?
* drainage basins in QLD
* QLD wetlands
* Commonwealth marine protected areas
* SA boat ramps (POIs?)
* Australian land use data (may be out of date though 01/02)
* Forests of Australia
* Vegitation cover of Australia (2003)
* SA recreational boating hazards
* Australian federal electrorial boundaries (dunno how useful this
would be at all, might follow roads?)

The murray/darling data could fill in some blanks in the current
rivers and missing rivers, and other smaller water ways?

South Australian Road Crash Statistics, do we mark black spots on maps at all?

The water cover page[0] suggests that you use water=tidal;surface=sand  
for the area between the high and low water marks (assuming it's a  
sandy beach). There are quite a few places where those lines can be  
many kilometres apart :)

[talk-au] Hume Highway / Motorway

2009-09-30 Thread Liz


I don't want too many posts, just some stuff to think about

Where the Hume Highway has been upgraded to a 2 lane each way separated 
carriageways type of road, it has been marked 'motorway' (renders blue on 
Mapnik)
Old Hume Highway segments are just 'trunk' (renders green on Mapnik)

For
There is a complete difference between the two styles of road.
Even the RTA has put up a sign with M31 on it
http://www.ozroads.com.au/NSW/Special/MAB/317.jpg
(this is just south of where the Illawarra Highway joins, facing southbound 
traffic)
these two are from further south with A31
http://www.ozroads.com.au/NSW/Special/MAB/14.JPG
http://www.ozroads.com.au/NSW/Special/MAB/311.jpg

Against
Some of the dual carriageway stuff is not technically a 'motorway'
as it has crossing road junctions.
Even on the parts with no crossing road junctions bicycles are permitted (from 
south of somewhere near Picton to I don't know where)
In general we Aussies map roads according to importance not according to 
appearance



Anyway, even if we continue to do exactly what has been done, we should mark 
the appropriate motorway segments with bicycles=yes so that routing is correct 
for them.

Right now those pictures from ozroads won't load for me
the links come from this page

[talk-au] changes to west gate freeway

2009-09-30 Thread Liz
citylink have just emailed me to tell me (and the world about changes to the 
west gate freeway
Dear Elizabeth,
 From October 2009, there will be significant changes to the West Gate 
Freeway.
 The section between the CityLink Tunnels and the West Gate Bridge will change 
permanently.
This will change  the way that drivers enter and exit this section of the M1.
(Your satellite navigation system may not have the latest road information.)
On October 3, the Power Street entry to Burnley Tunnel will close permanently. 
A new Hannah Street on-ramp will open on the same day, providing an 
alternative route.

I trust that on the same day the Melbin mappers will have this done?

For example, Telopea Park has these two that I think I can remember:

Does this look familar to anybody?

I won't be doing it, as I'll still be in Belgium.

Properly mapped my first village all by myself.  Bree where my better
halfs parents live.  Very cool to turn a blank spot on the map into
something especially in a country so well mapped as Belgium.

Before 

After: 


Still need to get most of the street names.

I've also been mapping the cycle node network here.  What they have is
cycle nodes which are numbered, eg 07, was near where I'm staying.
The number 07 has arrows pointing which street path to follow if you
want to go to 08 or 09 you then follow the 08 until you arrive at 08
and then choose a new number.  Very pleasant way to see the
countryside of belgium with minimal traffic, can highly recommend it
as a holiday.

To see the extend of the network see  as you
can see it covers all of flanders and you can visit everywhere!

There are already split tranks, rather than split motorways in OSM so
there is already precident for this, eg Bruce highway (A1) in Gympie:

http://osm.org/go/uethu...@--

Although on the other side there is precidence the other way, eg Bruce
highway (M1) north of Brisbane where there is non-ramp exits:

The Telopea Park references, outside of parentheses, would appear to be grid

You also get those sorts of number of decimal places when converting too.

I'm trying to think of the system, it was used in street directories
etc, you end up with like H56 as the grid co-ord, then you have number
of metres from the starting x,y co-ord.

Here is some info on the ACT grid"The ACT grid is a Transverse Mercator map 
projection that uses the
longitude of Mt Stromlo Trig Station as its central meridian.  It is
based on the Australian Geodetic Datum 66 (AGD66), which is modified to
take advantage of the ACT’s limited east-west dimension and account for
scale differences caused by the ACT’s height above sea level.  The
resulting ACT grid effectively can be treated as a plane (rather than
geodetic) system of coordinates using the formulae of plane
trigonometry, without the need to apply scale factors, grid
convergence, arc-to-chord, or sea level corrections. As a result, for
all but the most accurate work in the ACT, terrestrial, grid and plane
measurements can be taken as being identical."

http://www.actpla.act.gov..au/tools_resources/maps_land_survey/surveying_data/surveyors_information/coordinate_system

I think the reason you didn't get a match is because the grid reference is in 
yards not metres.

Aha! Thank you!
Using the downloadable tool they provide, I get the correct results
and they match what I get when I run proj4 (via the definition at
http://spatialreference.org/ref/sr-org/6628/ ):
>>cs2cs +proj=tmerc +lat_0=0 +lon_0=149.00929483 +k=1.86 +x_0=20

211550.06 600190.55

149d8'10.668"E  35d18'57.41"S 22.802

= -35.31595, 149.1363 and my guess was -35.31415,149.1374

I did stare at it a while, hoping that adding the position of Mount
Stromlo or something would give me the result in Excel. It does say
"units=m" so I don't think the yards come into it (still doesn't
explain the huge difference between ACT and AMG). But I suppose if
someone wants to import this data, they could use PostGIS.

There is about a 200m difference, depending where you are in
Australia, between ADG66 and DGA94/WGS84, which at first look is about
how far out your first guess was...

A quick google I also found this:

Mt Stromlo Trig, ACT
in Australian Trig Points

S 35° 18.968 E 149° 00.632
55H E 682768 N 6090043

and from the above link:

ACT Standard Grid Co-ordinates of Mt Stromlo Trig
E 200,000.000 metres
N 600,000.000 metres

Wonder why they didn't just set Mt Stromlo to 0,0...

2009-09-30 Thread Evan Sebire

I adjusted the redfearn ( http://www.icsm.gov.au/gda/gdatm/redfearn.xls ) 
spreadsheet  and the values I got were 149D 08' 10''.13261 and -35D 
18'57''.42808
If someone wants to convert the ACT data it may be easiest to use the 
spreadsheet and then the data can be automatically feed into the cells.

The Ellipsoid definition data:
Semi major axis (a) (m) = 6378160
Inverse flattening (1/f) = 298.25
False easting (m) = 20
False northing (m) = 4510193.494
Central Scale factor (K0) = 1.86
Zone width (degrees) = 6
Longitude of the central meridian of zone 1(degrees) = 149.009146139

Then use zone 1

ok I briefly looked at the file format. They are raster images in the ESRI
grid format. Gdal provides a plugin to read that data.

I haven't had time to investigate on how we can convert this to vectorial
data.

[talk-au] Google Wants to Map Indoors, Too

2009-09-30 Thread John Smith
I emailed westfields and centro, both are operators of shopping
centres, about getting access to their floor plans in the various
shopping centres they operate to add to OSM, unfortunately I received
no reply at the time, maybe this is why.

-

An anonymous reader writes "Google maps are getting extended indoors
next month with a new app called Micello that takes over where
conventional navigators leave off — mapping your route inside of
buildings, malls, convention centers and other points of interest. You
don't get a 'you are here' blinking dot yet — but they do promise to
add one next year using WiFi triangulation. At the introduction next
month, Micello will only work in California, but they plan to expand
to other major US cities during 2010."

This bug was tripping a lot of people up, not sure how much damage was
done as a result, but that bug has now been fixed and I've fixed up
the 4800 postcode where I added duplicate admin boundaries. The bug
effected at least 2206 and 2209 versions of JOSM.

and we should start thinking about taking the next move.
