Thanks for the clarification Ian.
Keep up the great work.

Hi Warren, thanks for your feedback. You sent me back to my computer 
to re-check some numbers. Remember that the 57,828 kms in the blog 
post only includes OSM highway tags from highway=motorway to 
highway=tertiary. Other road types, including highway=unclassified, 
track, residential etc, are not included in the totals. I just ran 
some Overpass Turbo queries to calculate the total length of other 
road classes in WA, and this what you get:



OSM ROAD CLASS



DISTANCE (km)



CUMULATIVE TOTALS

Motorway to tertiary



57,828 (as in blog)



57,828

Unclassified



87,195



145,023

Track



77,339



222,362


If you add motorways to tertiary plus unclassified roads in OSM you 
get 145,023 kms. This is very close to the total length of roads that 
is not managed by DPAW, as you quoted from the WA Main Roads report: 
147,676 km. In fact the difference is only 1.8%.


In addition to this, there are 77,339 kms of highway=track in WA in 
OSM. This vastly exceeds the length of DPAW managed roads (National 
Parks, Forestry) that you quoted from the WA Main Roads report (38,333 
km). (I assume that at least some of these "extra" tracks must be on 
private property?) It's difficult to compare the numbers any more 
closely than this, as Main Roads WA and OSM categorise roads in 
different ways.


Thus, the total length of highway=motorway + trunk + primary + 
secondary + tertiary + track in WA in OSM = 222,362 km. The total 
length of roads that are and are not managed by DPAW that you quoted 
from the WA Main Roads report is 186,009 km. So I reckon OpenStreetMap 
is doing pretty well really, /especially /on unsealed roads. (Plus, 
about 20,000 kms of residential roads have also been mapped in WA, as 
well as other road types).


Having said all that, I'm sure that extra roads will be added to OSM 
in WA and the NT, as you suggest. Northern Qld is probably in the same 
boat. However, the total length of these roads will be very minor 
compared to what's already been mapped.


Anyhow, thanks for keeping me honest, I'm glad I didn't stuff the 
numbers up that badly! Best wishes Ian :)

 From Main Roads WA report:

Mappers in WA have a long way to go.  I suspect a large percentage of
the sealed roads have been mapped on OSM.  The remainder are
almost all
unsealed.

The NT may be in a similar position.

Nonetheless an interesting  report.  Thanks for sharing.

I would agree with Greg on this.  I think a Park is a Natural or 
Recreational area within a city or Town.  They can also be National 
Parks, but I think the vernacular is to use Park. Reserve is also fairly 
common within City or Town boundaries, be it a Sports Reserve or a 
Nature Reserve.


Outside of a City or Town, the use is more National Park, Reserve or 
Wilderness Area.


There will be some blurring of terminology.

Do you mean without seeing them yourself Warren ?  I personally think
that you should only correct another mapper's work if you have
personally seen something that needs correction. I am sure there are
some exceptions. But here, in particular, you seem to have "negative"
information.

Its also worth remembering that highway= indicates the purpose of the
road or track, a number of other tags indicate its condition. In theory ....

Re: [talk-au] When is a Road a Track

[Warren]

I agree Eon4wd, my interest in OSM originated from my interest in 
bushwalking.  Often we can make an educated guess of tracktype from an 
aerial image and knowledge of the general area.  I suggest that if it is 
not clear you leave out the tracktype field, this implies unknown.


My point was really:

Do we accept the Main Roads Western Australia data as a list of 
officially recognised Roads ( highway = primary, residential, etc not = 
track or = path)?


I accept the point that highway = unclassified could be appropriate for 
a road that does not appear on the data base.

Hi Warren,
Tracks are of particular interest to me.
As a 4wder, I plan my travels according to the tracks and the 'grade' of the

If highway = Track is used it really needs the additional 'grade' tags
The Aust tagging guidelines is a good system see
http://wiki.openstreetmap.org/wiki/Australian_Tagging_Guidelines
Tracks need to be driven before they can be correctly described.
Armchair mapping has its place to identify that something maybe there, but the 
rest of the tags need to be correct as it dictates what type of 4wd is required 
to negotiate the track.
Is it possible to tag that the grade is 'unknown' ? which is more helpful to me 
than nothing or an incorrect guess.

[talk-au] When is a road not a road

[Warren]

In this case I know the roads, I have walked, ridden a bike, and in some 
cases driven them.  They exist, but they are in a restricted area.  This 
is possibly why they do not appear on the WAMR data.  I guess my 
question includes the concept of what roads should appear on the OSM 
map.  I know this discussion has been had before.  Do we accept the MRWA 
data as an "approved" set of public roads in WA?


I understand, and agree with, Warin's point about not changing data 
without good cause.  I also understand Sam's point about the "on ground 
accuracy" of the MRWA data.

[talk-au] When is a road, not a road?

[Warren]

I suspect the answer to this question  is simple.

Following Sam Wilson's post about the data sources available for Western 
Australian Roads, and using Sam's approach I have begun adding and 
checking road names in WA.  In  the area that I am currently working 
there are a number of named "roads" on  OSM (usually Highway: 
unclassified), that do not appear on the Main roads data.


If a road is not on the Main roads database does it automatically become 
a named track (Highway: Track)?

For info, I've just finishing reverting the remaining nodes from these
imports.  The last one was
https://www.openstreetmap.org/changeset/40792543 .  As previously
mentioned upthread, many of the objects had already been removed but
some of the nodes from some of the larger changesets remained.

Two issues that I spotted on the way through I've commented on on:

https://www.openstreetmap.org/changeset/40195392

It'd be great if a Perth local could have a look at those.

Two issues that I spotted on the way through I've commented on on:

https://www.openstreetmap.org/changeset/40195315

Using Strava cyclist heat map it looks to me like the roundabout (way
361673628) should be  a smaller diameter.
The other roundabout (north western side) way 351188658  has used the
same diameter, that too may need to be reduced?

Bing, AGRI and Mapbox imagery are not upto date in this area so cannot
be used.


https://www.openstreetmap.org/changeset/40195392

Similar situation - not available in the present imagery.
Way Arthur Street 37451474
Way Lord Street 346140242 and part of way 318945115.


It'd be great if a Perth local could have a look at those.

Might take some time.
In the short term would it not be 'better' to;

1) Reduce the roundabout diameters and remove the kinks (probably a more
truthfull representation of what is there)

2) Reduce the portrayed importance to the sections of these roads?

And then place fixmes on the ways?

I would also like to input into this discussion.

From the point of view of a user of one of the renditions of OSM maps I 
can see the point that the huts be labelled as Alpine Huts.
In Western Australia we do not do Alpine but we do have huts.  It would 
be nice to have the huts on the Bibbulmun track marked, currently they 
seem to be marked as toilets at best.

Can we redefine Alpine to mean any remote hut?

Thanks Warin for the reply.

wilderness_hut should not cause map clutter because they should only
be tagged in wilderness areas which by definition are largely empty of
man made features

but I accept that getting their zoom level changed may be difficult

so continue to tag as basic hut in NSW and alpine hut in Victoria?

Hi

I am new to editing.

I have noticed inconsistency in what are known in Australia as
Alpine or High Country or Mountain Cattlemen's huts.

In Victoria they are tagged  tourism=alpine_hut (see Bogong High
Plains, Mt Sterling and Lake Mountain)

In the NSW they are tagged as  shelter_type=basic_hut. (see the
Snowy Mountains, [except that you can't easily see them, eg Whites
River Hut, Schlink Hilton, Tin Hut])

I would consider retagging the Victorian huts to basic_hut or
wilderness_hut but there is a serious safety issue involved. I am
aware that I should not tag for Mapnik but downgrading the hut
status would be very risky for map users.

alpine_hut displays in Mapnik at zoom 13 but basic_hut displays at
zoom 16. It is practically impossible to find a basic_hut with
scroll and zoom, even if you know roughly where it is. I guess this
  is why Victorian huts are tagged alpine_hut.

These huts are the single most important feature in Australian alpine areas.

Ideally I would like to see basic_hut or wilderness_hut displaying
at zoom 13, there is heaps of empty space, at least in Australian
maps round these huts, then I would like to see the Victorian huts
retagged.

Your thoughts?


Unfortunately rendering 'rules' are world wide ...
Meaning if basic_hut or wilderness_hut displaying were displayed at
zoom 13 somewhere in the world there would be too much clutter for the
map to be usefull.

Personally I'd like to see these 'rules' being made fuzzy ... so in
places where little is shown things can be brought forward. Probably
best implemented the other way around, removing things untill the
number of things displayed per unit area is suitably small for reading,
but large enough for detail.

Re: [talk-au] Use of mapconnect and CAPAD data in OSM

[Warren]

Thank you Simon.  I would be interested in chasing an appropriate 
license to allow uploading this data.  The way I read the license it 
seems that the intent is that anyone can use the data for non-commercial 
or commercial uses provided they attribute it correctly.  I do not know 
what OSM requires or who to ask.  A clear answer would be nice.


I think I understand the limitations of the information.  I was 
specifically interested in boundary data, particularly for National 
Parks and conservation reserves.  While I admit the exact boundary can 
sometimes be important, for the majority of map users I think naming the 
reserve and roughly outlining the boundaries may be enough.  I have 
noticed that, while many of the reserves in Western Australia are named 
in the OSM data there are lots that do not appear.  I think that even 
with the limitations of the MapConnect data set it could improve the 
current OSM data set.


I did look at Ross's suggestion of the 2014 CAPAD data set.  From my 
initial look and my local knowledge it seems to be complete and more 
current.  Thanks Ross.  The data set is fairly big so it needs to be 
broken up to be useful.


Thanks all for your input
Warren

The data in Mapconnect can be up to 8 years old.  It originally came from both 
CAPAD and the states/territories, and was generalised to be consistent with a 
cartographic map at a scale of 1:250,000.
CAPAD has come from the states / territories, and probably from the national 
park authorities rather than the mapping agency.  There will be differences.
I would also be keen to hear what the limitations in the CCBY licence is.  If 
you want to use the data in Mapconnect then I can chase up an alternative 
licence/permission to use if the current license doesn't work.

Thanks,
Simon

[talk-au] Use of mapconnect data in OSM (Ross)

[Warren]

Thanks Ross
It seems to me that the human readable licence details imply permission 
but I will not reopen that argument.


From what you say it can be done provided we get someone from 
Geosciences Australia to specifically state that it is OK.  Now we have 
to find the person that is willing to sign away.  This may be the tricky 
bit.


The Mapconnect data is incomplete and not that wonderful but it is 
better than what is in OSM at the moment, at least for WA.  How much 
effort do I put into this task?


Any other comments will be welcomed.

With the current terms and conditions you need to have permission of the
work owner to add it to the database.

Something that is licenced CC-BY-SA does not imply permission.

There have been numerous debates on this pre and post licence change in 2012

See here for an example of what has been done previously:

[OSM-talk] Fwd: [PLOTS] Google connects with Public Laboratory Map Archive

see especially the Gowanus Canal (): http://g.co/maps/ds8bs - and check
out the credit line!

These were all public domain maps, not CC-BY, which many Public Lab
contributors' maps are. But it's still great to see uptake by big players.
One wonders if they'd accept CC-BY maps. Maybe we can put a big banner with
CC-BY on it in each map... :-)

Also i have to mention, this being the OSM community -- these are raster
maps -- aerial images, not vector data. i.e. not a competitor!

We have some exciting news to share – Google Earth is now using 45 of the
maps the Public Laboratory community produced!

The Public Laboratory Archive includes many public domain-released maps -
so that they can be redistributed without friction. Such is the case with
today's announcement -- Google is now publishing finished maps from our
archive that have the public domain designation. We are excited that Google
has connected with our open data archive, and hope that
other organizations will choose to do the same. The Google Geo Lat Long
Blog has a nice post on the new maps in Google. We hope to continue
distributing our maps to Google several times a year.  This first wave of
maps includes 45 total maps and 9 that are showing up in Google Maps as
well as Google Earth.

We’re preparing a news release now, which we'll hopefully send out later

[OSM-talk] Better integration with OSM from MapKnitter.org balloon maps

[Jeffrey Warren]

Hello - I was just enjoying the add a TMS background feature in Potlatch
2 (feel free to tell me to go to a different mailing list) and I created a
brief guide to inserting your DIY balloon mapping aerial imagery
(grassroots mapping/public laboratory style) as a background:

http://publiclaboratory.org/wiki/editing-openstreetmap-balloon-maps
(using data from )

It was kind of remarkable to me that the balloon maps seem to be well
within the precision of the GPS used to make the existing map of Mestia,
Georgia. In some areas, just based on how the GPS tracks wiggle on a
straight road, it seemed that the balloon map is a pretty great resource
for filling in detail (once it's well rectified, of course). See the
screenshots in the page above.

Anyhow, I'm the main developer for MapKnitter.org, which is where most
grassroots balloon/kite mappers in our community are rectifying their
imagery. I was thinking it'd be really nice to add a *Use your map to
contribute to OpenStreetMap* link/button, which could deep-link into a
Potlatch 2 page with the layer already set up.

Is that kind of deep linking something anyone is interested in
collaborating on? I can do all the integration from the MapKnitter side but
don't have much experience with Potlatch code. I could also put this in as
a Google Summer of Code idea but maybe it's too use-specific and actually
too small of a project.

Just wondering if this was interesting to folks.

Wow, how extremely useful! Thank you, Andreas. I implemented the deep link
and you can see it on the following map, which I had originally linked to
(it's lower down along the right sidebar):

http://mapknitter.org/map/view/mestia

I'll probably style it more like a button so that people see it. I also
made it show up only for maps which are licensed Creative Commons
Attribution or dedicated to the public domain.

Issue tracker: https://github.com/jywarren/mapknitter/issues/96

Thanks again. I made it possible to use OSM as a reference layer for
rectification so that it's possible to bootstrap by using existing
ODBL/CC-BY-SA data to rectify balloon imagery.

I also think there's a lot of promise for those simply taking photos out
the window of their airplane flight with a good camera -- especially when
the plane is banking :-)

As no-one else has responded, I will have to show my ignorance and

these lists that 'we' do not want data type 'X' in the main OSM  
database - it should be in a separate one. So, if you are proposing  
to set up a separate database and show how it could be lined to OSM,  
that would be really good.


Simply put, it is a complex RDF schema for information about graves  
and human remains. It also keeps track of annoying but related things  
like the location of the cemetery and the location of the grave in the  
cemetery.


I was reading about the German effort to record grave information on  
wikipedia; I thought it might be interesting to write a bridge so that  
lod-data  can percolate into OSM. I know that the api web pages  
discourage this, but in the long run I think it will become necessary.


There has been quite a bit of discussion about mapping historical  
things here recently and I wonder if this could be incorporated into  
some sort of general 'historicOSM' database?


I'd like that. My two concerns are that 1) we need better support on  
the front end to determine when and what should be rendered to the  
user and 2) it won't be practical for me to upload data to OSM in a  
manual changeset. We need better automation.

imagino que les dejaron puntos de ubicacion hecho de alpiste...

de verdad si usaron palomas mensajeras se podia sacar fotos de una ruta...
pero ademas esas camaras probablemente sacan solamente una foto por vuelo.
No habia CHDK en esa epoca -

han visto el libro de David Macaulay, Rome Antics que sigue una paloma por
encima de la ciudad de Roma? Las 'ortofotos aerias' que dibjua del punto de
vista de la paloma son tipicas de fotos aerias hecho con globos:

 Interesante , de hecho se podria decir que son las primeras otrofotos
 no?
 Mi duda es si las adiestraban para que hicieran fotos de un punto
 concreto o por el contrario era totalmente aleatorio.
  Nosotros aqui discutiendo que si cometas o helio, y he aqui lo que he
  visto en internet:
  La solucion definitiva. Todo un clásico.

hablando de bateria... quizas se lo puede combinar con un globo de helio --
no porque estoy obsesionado con globos de helio, pero para que se quede
inmovil sin usar electricidad...

Si - el Knitter es un proyecto que estoy letamente desarollando... y lo
diseñe como un herramiento simple y facil, no para profesionales. Los
miembros de la comunidad Grassroots Mapping mas seriosos usan Photoshop y
GDAL. Pero recien muchos han podido crear mapas no tan malos con el Knitter,
y de verdad no hay tanto dificultad en añadir distorcion esferica al Knitter
-- quizas lo hare (bueno, es codigo libre... si a alguien le gusta
javascript... ;-) )

tambien estoy siempre enrollando, enrollando... hemos a veces usado
bicicletas para acelerar el proceso:

Y una vez, un carro, jaja:

que no te puedo recomendar... es... un poquito peligroso.

 Tambien he intentado usar el Cartagen Knitter y tuve varios problemas
 (comente algo en la lista inglesa hace varios meses).  El primero es
 que no se toma en cuenta la optica de las lentes de la camara, la
 perspectiva, las distorciones, el efecto que tiene el aire en el
 white-balance de la foto (que los objetos se hacen mas azules con la
 distancia) y varios mas.  Ya se que seria casi imposible tomar estas
 cosas en cuenta en HTML5, pero existen programas que calculan estas
 cosas.  Hugin por ejemplo tiene una base de datos de camaras con sus
 parametros opticos y si no es una camara popular, puedes calibrar la
 camara tu solo.  Tambien usa varios parametros de los tags exif en las
 fotos.

Re: [Talk-es] apoyo aereo

[Jeffrey Warren]

cometas son muy eficaces si se entiende bien como usarlas... per a veces me
parece mas un arte que una ciencia.

en la comunidad Grassroots Mapping (grassrootsmapping.org) hemos tenido
exito con globos de helio (y tambien cometas, pero no tanto), volando a una
altura entre 300m-1300m con camaras baratas -- usando un cable para dirigir
y bajar el globo despues.

aca por ejemplo hicimos un mapeo completo de una ciudad en Georgia (el pais,
aunque soy norteamericano y igual tenemos una Georgia aca):

http://grassrootsmapping.org/search/mestia

El herramiento Cartagen Knitter que hice para 'coser' fotos aerias genera
TMS  GeoTiff

no se para que y que tipo de ortofotos necesitan pero es una manera bien
barata de sacar mapas nuevas de areas no tan grandes. En el caso de Mestia,
Georgia, el mapa era de 5.5x1 km en tamaño, y nos costo ~$200 (que seria
mucho menos en euros pero me pongo triste en calcularla)

aca tienes la guia ilustrada: Illustrated
Guidehttp://grassrootsmapping.org/guide/

  Oye, tu cometa es estratosférica, ¿no?. ¿A que altura calculas debía

  la cometa? ¿Cuanto hilo tenía el carrete?¿Que tipo de cometa usas?
 
  La foto, con mucho ruido. Es una lástima que las Canon compactas, que van
  tan bien, tengan tanto ruido. La mia era una Ixus65
  http://robertopla.net/blog/estrenando-camara.htm
  Hoy uso una Panasonic Lumix DZT-7

 Y la Lumix tiene un modo para tomar fotos en serie cada varios
 segundos?  El problema de ruido es que con la poca luz que hay ahora,
 y con la oscilacion continua, tengo que usar 800ISO o 1600ISO para
 evitar fotos movidas.  Es una pena porque la camara tiene 12
 megapixeles pero la resolucion real debe ser menor de 4 MP.

 Hay varias maneras de estabilizar la camara, pero entonces (y sin
 control remoto) la camara miraria directamente abajo y cubriria muy
 poco terreno.  Supongo que existen mas soluciones, pero realmente
 empece hace poco y todavia no tengo todo el proceso bien definido.

 El tipo de la cometa creo que se llama Sutton Flowform y es lo tipico
 de KAP.  Tengo 1200m de hilo pero en mi parte de la ciudad a 666m de
 altura (2 mil pies) ya comienza la zona de aterrizaje/despuegue del
 aeropuerto que esta a 30km de aqui :(
 Por cierto en el link de los tiles ortorectificados si eliges un zoom
 menor y pinchas en Show picture data, te muestra la posicion de la
 camara que se ha calculado desde cada foto, incluida la altitud (por
 lo menos en firefox lo debe mostrar).  Todavia no he puesto en la wiki
 la informacion del proceso que sigo, pero no es del todo muy bonito ni
 profesinoal, pues el calculo lo hace un programa hugin que en
 principio es para hacer panoramas.
 Me da curiosidad que precision tiene la posicion calculada de esta
 manera, comparando con GPS por ejemplo.

Re: [Talk-pe] mapeo con globos y cometas

[Jeffrey Warren]

Hola todos -

Primero, les digo que me parece una idea muy interesante usar imagenes
aereas (de globos o cometas) para realizar mapas en OSM - en parte porque
esos muestran mucho mas que simplemente lineas y puntos. Y como pueden
imaginar, es muy divertido trabajar con estes herramientos.

http://grassrootsmapping.org/search/cantagallo

Pero en el caso de Canta Gallo, como que hicimos ese mapa con la gente alla
y es propiedad de ellos, es muy importante que nosotros les pedimos usar las
imagenes... puedo imaginar que los quieren mantener privado. Bueno - en este
caso no creo que sera problema usarlas. Johna conoce a algunos que siguen
trabajando alla y puede preguntar.

OK pues como integramos ese tipo de imagen en OSM? Se puede generar un TMS
(mosaicos) que se puede abrir en JOSM, igual a los imagenes de Yahoo
satellite, por ejemplo.

Saludos a todos, y buena suerte!

Jeff

 y esto,el último resultado de su trabajo:

 Hacer mapas con imágenes aéreas es una experiencia que ya ha pasado en
 Perú, junto con Jeffrey se realizó el mapeo de Cantagallo
 http://shuawa.escuelab.org/content/mapa-areo pero no está aun mapeada en
 OSM. Estoy escribiéndole a algunas personas que participaron en ese
 taller por si se animan a venir al mapeo del 21/22 y compartir lo que
 saben. Yo no estuve en aquel taller.

 Dejo allí los enlaces para la inspiración...
 saludos!

Re: [OSM-talk] Historical Mapping Examples?

[Rob Warren]

Hi Kate.

I run the Muninn Project (http://blog.muninn-project.org/) which extracts 
data from First World War scanned archives. I've been lurking on the 
mailing list for a while now to get some background before asking 
about this very topic, but you beat me to it.

Would anyone be interested in creating Open Trench Map - 1918 Edition?

Historical mapping has some problems that are a bit different from 
conventional mapping in that 1) everything is a timestamp and 2) research 
people care very much about the data being 'wrong'.

So, besides the fact that trenches keep getting moved, bombed, renamed 
and worked on as the front moves back and forth, the maps also reflect what 
people *think* is happening on the other side.

So we get a German map of British trenches, a Canadian map of German 
trenches and the differences between what is happening and what people 
think is happening are of great historical value.

Unsuprisingly, sometimes different maps from the same army at the same 
time don't match up.

We have a lot of geo data that can be used to track individual soldiers on 
the map over the course of the war too, down to which trenches they were 
in.

I spend most of my time on data extraction, but I think historical mapping 
is something that needs to be worked on. I'd be interested in setting up 
an informal working group or exchange, please feel free to write me off or 
on-list.

best,
rhw

 Hi All,

 I'm attending THATCamp this weekend and would like to talk about
 OpenStreetMap.  THATCamp is an unconference specifically related to
 technology applied to the digital humanities.  One area I thought
 would be of interest would be historical related areas in
 OpenStreetMap.  I was thinking areas with historic value, rather than
 areas that are mapped and no longer exist.

 An example near me would be Arlington National Cemetery:
 http://www.openstreetmap.org/?lat=38.87964lon=-77.06507zoom=16layers=B000FTFT

 Anyway if you have an examples along that vein that you think are
 particularly good please send them along.

 Thanks,

 Kate
