Adding sport= tags to leisure=pitch.

Posted by Warin61 on 28 April 2016 in English (English)

I am presently targeting Australian 'leisure=pitch' that don't have a 'sport=' tag and trying to identify the sport and add the tag. Why? Well I added the osmwiki page for 'sport=netball' having found these to be missing or incorrectly tagged while some 1,300 were in the data base. I then went around adding them, or correcting incorrect entries where found. In doing this I noticed that in these areas sports grounds were poorly represented or tagged. Using the web to look for netball courts resulted in a doubling of the number of netball courts in the OSM data base! So how to find these areas where sport is not represented as good as it could be? I chose to use taginfo and search for leisure=pitch and sport!= (tags with leisure-pitch and no sport) while this works .. there are a lot of them ... meaning the work spreads over several days and I was repeatably looking at the same things! So i chose to add the tag 'fixme=sport=?' to the places where I could not identify what sport was played there. The search can now be 'leisure=pitch and sport!=* and fixme!=*' and that removes the places I have looked at.

I have now done NSW! I am targeting Melbourne, then country Vic. Then ... S.A./Qld.

This has increase the quantity of sports ... netball is now around 3,800! Increases for AFL, touch_football (I have yet to add a osmwiki page for this), cricket, basketball, softball (yep .. needs a osmwiki page too) and discus, hammer throws and long and triple jumps (again .. needs a osmwiki pages! ).

Using LPI information to add street names to Sydney NSW Australia

Posted by Warin61 on 13 December 2015 in English (English)

{edited Jan 2016} There are a fair number of streets in Sydney missing their names.

'Cleary' has negotiated the use of 'Land and Property Information' from the NSW government for use in OSM. Yea!!

So I have started to use their base map to add the street names using JOSM. There is a fair amount of information on that map .. house numbers, parks, post offices, police stations, libraries... very usefull.

So .. if you want to help .. instructions;

Adding LPI imagery to JOSM

This is now available on the pull down list. You want AU (for Australia) then LPI NSW Base Map. Go to 'Imagery' on the top bar, select imagery preferences, then scroll down to and click on the 'LPI NSW Base Map' so it highlights and then click on hte 'Activate button'. It should now appear in the lower window.

Finding areas with missing street names

Too easy ! The above can run a few days behind.

OR Looks to be running up to 1 hour behind.

Using JOSM to find the streets with missing names

Download from OSM the area you want to edit. Then CNTRL F ('Find') and type in 'type:way highway=* -name=*' and press enter.. that will select all the 'highways' that are ways without names. Includes cycleways, paths etc. Select the NSW LPI Base Map imagery and zoom in on one of the selected (red) highways ... select the individual highway and add the name .. and add the source .. I'm using 'LPI Base Map Jan 2016' as that identifies what I am using .. if any updates come along then it should be easy to see. Once that one is changes .. CNTRL F and enter to find the remaining ones ... if you forget to select an individual highway you will name ALL the highways with missing names... CNTRL Z is your friend to undo the error.

If you want to exclude footpaths then 'type:way highway=* -name=* -highway=footway'. Same system for cycleway etc...

Yes the attribution and permission of LPI copyright has been done. Thanks once again to 'cleary'!

There is also an improved resolution satellite view from LPI too ... I think it also has less parallax error too. It lacks the names, and other details on the LPI Base Map. Similar instructions to install it in JOSM.

tagging cricket nets

Posted by Warin61 on 29 September 2015 in English (English)

These are used to warm up and practice bowling and batting for cricket.

Previously they were tagged leisure=pitch and sport=cricket_net ...

But someone has pointed out that this in not a sport...

A documented suggestion is to use sport=cricket, barrier=fence .. but the argument is it is NOT A SPORT so you cannot use sport= anything! That suggestion is on

I'd think similar 'restrictions' will be imposed by the pedantic on other pitches that are only used for practice ..for example - half sized basketball courts - only used for practice .. not full sized due to space restrictions. So not a sport.. just practice.

There are similar concerns for sport=exercise, sport=fitness .. these too are not sports.. yet are found in the OSM data base.

So .. what tag to use?


exercise=cricket_nets description: A fenced area where cricket batting and bowling can be practiced.

And then there can be other 'exercise'

exercise=exercise_station example: small areas set aside in parks with features to provide specific exercises. Usually free.

exercise=fitness_center example:An establishment with machines to improve physical fitness. Usually for a fee.

And so on ..

Or ?

leisure=practice_pitch ?

sport=cricket, basketball etc ... this would indicate it is a practice pitch .. and that the full sport is played elsewhere. This is more restrictive, not covering exercise stations etc.


leisure=* .. as per normal then add sport_practice= cricket_nets etc .. indicating that only practice for that sport is conducted here. sport= would indicate that bother the sport and practice for teh soprt would be possible.

Re:The order/thinking/philosphy/system of OSM tags;- Consistency

Posted by Warin61 on 24 January 2015 in English (English)


What are 'we' tagging'? And Why are 'we' tagging it?

My preference it to tag what is seen ... not what is consumed, not what is done. An example: There looks to be some angst over the new tag 'man_made=tap' tag. And that looks to come from the supporters of the tag 'amenity=drinking_water' humm ..

That tag 'amenity=drinking_water' .. does not sit well with me. I agree it needs to be tagged, but is this the best way? It is not consistent with other tags .. such as;

amenity=pub .. should this then be amenity=beer_drinking or amenity=beer?

amenity=restaurant .. should this then be amenity=eating or amenity=food?

My thoughts are that 'amenity-drinking_water' should become a tap, a blubber, a fountain .. what is seen. Why is this better? Consistency with other tags. And then .. well for me I like to know if I can fill my water bottle from it without making a mess (tap and maybe a fountain). Or I like to know if I can drink from it without needing a cup/water bottle (bubbler).

----------------- next time - logical grouping of things?

The order/thinking/philosphy/system of OSM tags?

Posted by Warin61 on 14 January 2015 in English (English)

I'm a bit confused by the highest level tags... what is the thinking behind them? Probably this has grown without too much coordination, but it is leading to a mess.

Should there not be some order/thinking/philosophy to them?

For example

highway= .. is tagging a thing.

amenity= is tagging a function/service.

Would it not be best to adopt one order/thinking/philosophy/system and stick to it? I think the present tags have evolved from different points of view and would be best reorganized, but before that happens some guide lines need to be established as to the order/thinking/philosophy/system that should be used. That would help people proposing new tags .. that would fit in with the system, rather than confuse it further.

If highway= were to be tagged as a service then it would be transportation=motorway, primary_highway, railway, ferry etc.

If amenity=drinking_water were to be tagged as a thing then it could be tagged as water=blubber(,sea, river, pipe, tap, )

Thoughts? I've raised the issue on the tagging talk group too.

improper tags

Posted by Warin61 on 6 July 2014 in English (English)

A Comment from BlueTiger on 3 July 2014 at 14:14 in another entry; " Most of the times when I travel I will leave the OSMTracker running and update new POIs. At times I have skipped uploading POIs as they don't have proper tags in OSM. Unfortunately I have taken a bad choice here, I should have updated them anyway and requested for new tags."

I've seen a few tags that were not "proper" in an OSM sense .. but they make sense if you know what is there. Unfortunately getting somethings in to be "proper" in OSM looks to me to be difficult due to the numbers and location game e.g. Radio Telescope. While other things that are not consistent get through - e.g. highway=footpath and highway=path. So I'm inclined to tag all things I consider important in either a navigational sense or a facility. Make a tag note= with some explanation if necessary. This way the data is there .. even if used at this time. I'd rather have the data recorded rather than thrown away. The "improper" tag can be changed latter if a more appropriate tag is available.

Targeting inappropriate 'layer' entries.

Posted by Warin61 on 12 April 2014 in English (English)

I'm presently targeting things that have inappropriate 'layer' entries in my area.e.g.

highway, layer -5 ... no tunnel/covered etc ...

park layer -2

I assume this way done for rendering issues. The areas look to be best served with multipolygons.

There do not appear to be tools to find these inappropriate layers, so I'm using a simple text editor to find them., then JOSM to do the editing.

Automated Street name abreviation replacements

Posted by Warin61 on 2 March 2014 in English (English)

I'm toying with automating the replacement of abbreviation of street names e.g. St to Street, Ave to Avenue etc. It is tedious to do that by hand and the automation process can limit the replacements to tagged 'highway's and to the end of the name tag so things like St Andrews won't get changed to Street Andrews! It would be used on .osm files making the changes, a separate text file documenting the changes (so you can check), the abbreviations and their replacements would be in a text file so additions could be made by anyone (in any language). To upload the changes JOSM would be used.

Intro ?

Posted by Warin61 on 11 February 2014 in English (English)

Not sure what this is for .. so I'll just do a general introduction...

Mapping - mainly Australia, Sydney .. resident in the Epping area. I do travel elsewhere (I'll take a look at my GPX tracks and see if I have stuff to add when time permits).

Location: Epping, Sydney, City of Parramatta Council, New South Wales, 2121, Australia
