The invalid areas of the map

Leaving a comment in the changeset can get the wrong response… in which case I leave it a week or two for tempers to dissipate and then make further comment .. possibly in much more detail so there is no misinterpretation. I use osminspector to monitor these in ‘my’ area. http://tools.geofabrik.de/osmi/?view=multipolygon&zoom=6

Nottingham's Mysterious Plaster Boys & Girls

I have seen similar things in South Australia… portable wooden ones placed in the center of the road to inform when school in/out times are .. usually there is some speed restriction during these times and the wooden warning is a very helpfull warning. Don’t know what they are called.

Rendering … well some do show them, others don’t Make your choice as to what one suits you.

I too like your entries. Gives another view on things.

National Park Rendering Issue

There may be (legal) differences between NP boundaries and coastlines. I would not move them unless I knew what was what with the park boundaries.. and coastline is high tide?

There are also ‘Marine National Parks too - some of which may not touch land.

Rendering… which has priority land cover or land use? Are both transparent so that other features can appear - e.g. a bench, shelter, gust house… ?

Possibly someone thinks that the rendering with the tag leisure=park is better than without it… contact the mapper who placed the tag?

Out of Town Experiences

Use caution with boundaries. From your photo .. that may have been the boundary in 1877 .. but boundaries move! New places get inserted, populations change .. all leading to the change of boundaries.

Survival Techniques for Hot Weather in Carlton

Climate is relative. ‘We’ do acclimatize to where ‘we’ live. People who live in Darwin, Australia get use to the daily maximum of 32℃ year round. When it gets to 25℃ they put on jumpers! They even get use to the ‘dry’ season (~10% humidity) and the ‘wet’ season (90% humidity). It is the rapid changes ‘we’ don’t handle well.

Today’s weather in Australia “winter has arrived” 21℃ Sydney, 12℃ Hobart, 33℃ Darwin.


Clothing .. cotton works well … but holds lots of water and takes time to dry. Modern synthetics work better, hold less water (much faster to dry) and last longer. They are not as good with smells - need a good wash now and then rather than just wearing them day after day. Cost benefit ratio I am not sure of.


Salt is also a taste thing.. people like the taste so it gets added to food and drink to make people consume more of it and therefore make more money for the sellers of these products. So called ‘sports drinks’ are usually a waste of money for most people.

Zoners Greenhouse Commerce Twp Michigan 48382

Hi, While you give a Lat/Lon location .. for accuracy you do not give a datum of the measurement .. So these could have differences of upto 100 yards. More practically .. there are 3 buildings just south of the road near that location .. 2 of them to the east look to be greenhouses, the other one looks to be a building with an addition of a green house to the eastern side of the building.

I have assumed that single building with the extension of the greenhouse is the one you would like tagged? I have tagged that building with the name and address (using East Commerce Road not Street).. but it should also be tagged as a shop? tag shop=plants might be suitable?

Where are the Builders / Building Contractors in the JOSM Presets?

Oh.. on the JOSM presets .. only follow things that people have complained about on their pages. Some of the things implemented are not ‘good’. Some of the things not implemented demonstrate how out of touch the presets are.

Where are the Builders / Building Contractors in the JOSM Presets?

For past use use taginfo ..

e.g for builders https://taginfo.openstreetmap.org/search?q=builder#values

So .. you have a choice .. craft, office or shop. What do you think fits best? Then use that. If nothing fits then think of something that does … use it .. and if you think it is ‘good’ document it on the OSM wiki.

Good Luck.

My latest additions.

The LPI base map should have the road names and addresses on it, and as it is ‘approved’ for use in OSM you can use that to enter the data. The LPI Imagery too is very good - having much better resolution than the other imagery that is available, so you can use that for building outlines, tracks. These should be available with ID.

Always best to start with a place you know well. I also map areas where I am going on holiday - that way I have a better map and more knowledge of the are before I go. Ant then once I return I can map those things I missed from the remote mapping. Have fun.

Why copying visual style of paper maps is not a good idea

Copying a paper map style .. makes it easy for those familiar with that style. But as you point out the styles are country specific .. so not that advantageous for a world wide map. But using the basic ideas of colour, line widths, symbols where these are uniform across a wide source of these paper maps is a good idea - these would be well evolved and widely recognized.

Why copying visual style of paper maps is not a good idea

Colour; There is a fair proportion of the population that have difficulty distinguishing colours. Low contrast colours are harder to distinguish between each other. Line widths; Thin lines are hard to see, especially at a quick glance or in bright sun. Symbols; These are fairly ‘standard’ now .. it is only copyright issues that annoy.

Evolution; Paper maps have evolved over time … probably as good as they are going to get now, Electronic maps are still evolving - so there will be divergence at present while different ideas are tired.

I have all the maps types/makes you mention .. plus Australian ‘Natmaps’, ‘Geoscience maps’ (both govt.. form the same department with name changes by politicians), Westprint maps, Hemma maps and probably more that I cannot remember now. They all have different styles. But the basics are very similar - small colour range so easy to distinguish each colour, minimum and maximum line widths - so you can see them easily and they don’t dominate too much.

Review: OsmAnd: Navigating With OpenStreetMap

I use it for bicycle and pedestrian navigation… where I like the rendering of things I can use.

The redraw speed will probably depend on your phone operating speed…

Now the Computer Has Died

To guard against PC failure I run 2, one laptop and a desktop. The laptop walked windows 7 .. I have recently ‘updated’ (or ‘crossgraded’) to windows 10… I refuse to call it an ‘upgrade’! umm I am thinking of debian… I don’t use bluetooth, Wifi is essential though. There is a fair amount of ware on the keys, headphone socket broken, some small bits of plastic distorted around USB sockets… just ware and tare. I may replace it .. it is one of those Aldi ones… I may well wait untill it dies or at least starts to hicup.

The (older) desktop walks windows XT and that won’t be replaced untill it fails (or a lot more years have passed). It is mostly isolated from the network .. occasional updates of software are about it. data can come via the laptop and a USB stick.

Both look healthy at the moment. I use the laptop fairly intensely, the desktop is used for stuff that takes time and has two good screens set up on it. When you have the funds/inclination it may be a good idea to get a second PC as backup? For backup of data I have two 2T external drives.. they are getting full. And, of course cloud storage - some of it open to family. I will wait for the next ‘sales’ to get more local backup disks.

Improving the OSM map - why don't we? (13)

Amount of information;

In part the problem comes from a fixed rule set applied everywhere - in some places those rules work well, usually in places with lots and lots of information. In other places with little information there is a blank map using these same rules! Possibly the rule set need to ‘look at’ the number of nodes rendered over a given area .. and adjust the number of nodes to give at last some information.

Importance of information;

For cities/towns/villages the easiest way to judge their ‘importance’ is to use the population. As an example I have come across tagged ‘towns’ with populations of 0! Yes they are ‘towns’ as determined by the government … but they are not ‘towns’ to me or other map users. Of course different map users will have different ideas of what is important, a boat user will want waterways, a sports car driver will want paved highways and a 4WD will want unpaved roads and tracks.

City Heights, Mapperley Top

Photos are so much better than written notes - they don’t miss spell, miss things and include unobserved things. And they are much quicker than my writing. Assistance from others .. I tend to avoid it as I spend more time explaining than gaining information. So I gather what I can and get on to the next thing. As for flat numbers .. no I don’t bother … as there is far too much other stuff, that I regard as more usefull to more people, to do. e.g. misstagged ‘towns’ with populations of 0!

Adding sport= tags to leisure=pitch.

Touch football … popular in Australia, similar to rugby without the tracking/scrums, no goal posts and half the size of a regular rugby pitch. Humm https://en.wikipedia.org/wiki/Touch_football - so varies by nationality! Demonstrates why it is important to do a osmwiki page write up. May have to do an extension touch_football_aus touch_football_rugby touch_football_usa Humm … may be better to tag sport=rugby rugby=touch, sport=american_football american_football=touch ?

The tag ‘sport=multi’ does not tell what sports are played there … better to use ‘sport=american_football;baseball’ (as an example) as that tells what actual sports are played there…. better again to have those separated up into overlapping pitches - each pitch with its individual sport tag as that tell how many pitches are for what sports and how they are orientated. way/117318615#map=19/-33.74881/151.10267 shows overlapping pitches of two different sports.

Adding sport= tags to leisure=pitch.

Some. It does make sense to have these for cash strapped schools!

*If there is good imagery;

I mark each pitch area and tag each separately. Netball courts are longer than basketball courts, while tennis courts reside inside both - I only mark the ‘pitch’ area .. not the bigger ‘play’; area. For tennis + netball way/117318615#map=19/-33.74881/151.10267 Cannot find the basketball, netball, tennis ones at the moment.

*If the imagery is not great; I mark the larger pitch area and tag sport=netball;basketball;tennis …. For some I can separate out the tennis court.

Unfortunately I am missing out on what I think are ‘hand ball’ courts - marked as 4 rectangles on a paved area. I should just tag them “leisure=pitch, fixme=sport=handball?” but I have been ignoring them!

Why local assumptions are wrong for an international project

Getting unpaid volunteers (who actual are paying to contribute e.g. their time) to do something that is against their inclination is extremely difficult. It may be better to act like a tree and bend with the wind rather than try and stand against it?

OSM has to accept that in some parts of the world vehicles are driven on the left side of the road, where as in others they are driven on the right. Perhaps OSM needs ‘local’ definitions for some tags … A Russian ‘hanger’ could be tagged building:ru=hanger much as OSM has for names? And I believe the type of building you refer to is a ‘Nissen Hut’ https://en.wikipedia.org/wiki/Nissen_hut just at add an British flavor to the names :)

Fuel. In some parts of Australia ‘Opal Fuel’ is sold … not ‘regular’ fuel… this is an attempt to stop the young sniffing fuel to get high… leads to brain damage. The RON/etc is the same but visitors get told all sorts of things about Opal Fuel being bad … never seen any real evidence of harm.. and I have used the stuff. I have also used ‘avgas’ (aviation fuel 100) for much the same reason .. again no harm to the engine (lot more lead out the exhaust … but there are very few people out there to suffer from it).

Supermarkets? These too are locally influenced. A super market in Switzerland has lots of chocolate, in France wine. An ‘outback store’ in Australia has kangaroo tails, flour comes in 20 kg bags and the bread is in the freezer. One of the joys of travel is experiencing this stuff.

Enjoy the differences and adapt to them?

Using LPI information to add street names to Sydney NSW Australia

Well the vast majority of LPI Base map road names are now in the OSM data base, say 95%+. There are a few country lesser roads to be done. Of course there are those roads that are not named in the LPI data base .. they may not have names at all. I usally add a note tag to these to avoid looking at them again with the LPI data.

I’ll target the remaining country roads later, once I have regained my enthusiasm for the task.

So…that is the vast majority of NSW roads named.

Mapping Thorneywood Mount

I do like that people are looking after their own area. Neighborhood watch’ type of thing. And the fact that they are not afraid to approach you and voice their concerns is great! Much better than calling the local Police out. Always usefull to think about their view - some strange person wandering out the front of their place taking photos could be a concern. Class? Well some might take that view, I think it is more a perception of rights, protection and privacy.
