Review of Africa Highway Tags

I think there are enough varieties of highways. It is a mater of getting the right one.

For ‘rural residential’ that are ‘dead ends’, then I would use highway=unclassified.

For ‘rural residential’ that continue from one hamlet/village to another, then I would use highway=tertiary.

Many streams and rivers in desert areas are dry most of the time. Use the tag ‘intermittent=yes’ and/or seasonal=winter, summer, spring, autumn? One such river has an annual regatta … the regatta was called off one year because there was water in the river. https://en.wikipedia.org/wiki/Henley-on-Todd_Regatta

Streams that go underground … layer=-1?

The ‘children’ can be made into old fashioned ‘silent cops’.

Base is a steel coil spring .. as fitted to some car suspensions. Equip the children with steel shoulders.

Vehicle hits ‘child’, child bounces out of the way .. but springs back repetitively down the vehicles body work. Smash repairers were quite well acquainted with the damaged caused by these ‘silent cops’ .. some of the ‘cops’ got quite battered. Usually placed on corners where people would try to ‘cut the corner’ or in the center of a road junction. Very effective deterrent … the smash repairers probably subsidized there construction.

In South Australia they use wooden 2 dimension children to signify when you should slow down for school zones .. they put them in the middle of the road so people cannot say they did not see them. Not seen any of them the worse for lack of driver attention. I think if you hit one you’d have a bit of explaining to do. They may have stopped doing this .. all those electronic flashing signs .. pity, I quite liked the individuality of them.

Possibly importing USGS forest data

Just to be clear. What you are entering is not landuse=forest, but the tag, presently, natural=wood.

The tag landuse=forest should be used for land that is used to harvest products from trees, much like a farm. While these areas may be clear felled from time to time and therefore not have trees on them at this time, they are still being used for forestry.

The tag natural=wood can be applied over and landuse tag if required.

waterway=dam + beaver_made=yes

There are animal made paths, usually narrower than human made ones.

Hi,

My sympathies to the chap that has done the landscaping! Should have done it on the other side so he can enjoy more of the view of it :)

You can add it. But should you?

All relative. There are large parts of the world where OSM mappers are not constantly active. In these regions roads may not well represented.

Story .. a remote road maker having made his remote road returned along it a year after its construction to find a building constructed right across it. The reason for this.. they wanted any visitor to report to the buildings occupiers before proceeding. So the road builder made a bit of a road leading around the building .. so he could get his bulldozer, grader and trucks around it. Point being - even remote locations have things happen fairly quickly and they won’t go on the map untill someone comes along who cares.

Should these things that don’t have frequent checking not be added to the map will result in large areas of the world being blank. So there is a balance. So I do add things that may get ‘out of date’ before they get checked .. but they do provide an indication of what was there .. and I expect to be there for some time. Things do change, highly unusual for building to appear across a new road though!

Time zones? I don’t care. If they were rendered on the map I’d not be using them anyway, I run on when things open/close. Where the mobile phone works then you have the time off that and an app for time zones. If someone wants it within the OSM data base .. fine go ahead, I don’t expect renders to use it, same as any other feature in the OSM data base, the rendering is selective. And that selection results in some things being frequently added, checked and regularly adjusted compared to other features. Things will sort themselves out over time.

The centre of Rome

Interesting.

Most European road signs direct people to the railway station .. and I’d take that as the ‘center’. It is usually the place where the ‘central’ tourist office is.

In Australia.. I’d take the center as the post office. Cultural? Or I am not much of a tourist here?

So .. the ‘center’ … depends on what you want. A visitor would usually first want the tourist office? A local probably knows where they want to go, so won’t require some indication of the ‘center’. A large city may have move than one tourist office, a simple way of indicating the ‘central’ office might be the location of the name of the city? That works where the ‘central’ tourist office is not on the outskirts of the city (as it is in various Australian cities). So I have no good guide as to where it should be.

Harare gets a new name

One reason why people miss things like this … they are used to seeing the usually thing there and are oblivious to it. a new thing comes along .. and it might be fine, they don’t see it as a replacement for the original.

Same thing happens when speed limits are changed .. but the sign is in the same place .. the regulars ‘know’ what the speed limit was and continue using the old limit .. they don’t look a the sign they have gone past for many many days. Easier to pick these things up with a change map.. could be an idea for checking for errors? It needs to be configurable for the dates .. I may not notice a detrimental change for quite some time (weeks to months).

Introduction

Welcome to OSM. The vast majority of people try to ‘do the right thing’. A few PoGo players may not realize OSM is used by things other than PoGo .. thus they might see no harm in distorting the truth. Only a very few will deliberately create harm.

Your diary entries are broadcast to the OSM world, not limited to your area :). As such a good way of getting ideas out to the rest. There are also the talk channels - email list etc. A summary of contact channels osm.wiki/Contact_channels

Have fun with your mapping.

Overpass queries I should turn into maproulette challenges

Lots of missing info in the OSM data base e.g.

leisure=pitch without osm.wiki/Tag:sport=..

highway=* without surface=

……………………….. There are also depreciated things … like sport=football.

I am not proposing anything, but I am saying that landuse=logging is very poor. If the condition ‘logging’ needs to be tagged then don’t use landuse, as it is not a use .. but an activity .. like sport?

LandUSE=residential, commercial, industrial, farmland, forest(ry) … all uses landCOVER=wood,grass etc

As I said, logging is an activity. Does not fit in the present OSM tagging structure .. if it needs to be tagged than we need a tagging method for it… I have nothing as yet .. dictionary .. for activity to se if I can get an idea … no .. nothing there.

As far as what is verifiable .. yes .. but the logging itself is short term .. like a car parked, we don’t map that, so why map logging?

. The before/after logging is landcover… possibly using height to signify the relative sizes? Further complications … I think you are using ‘logging’ for clear felling .. where all the tress are removed. There is also ‘selective logging’ where only some trees are removed.

Sorry that did not format well

Where wooded vegetation is ‘harvested’ for produce ..

for live tress suitable for transplanting then landuse=plant_nursery is suitable

for dead trees (wood produce), or foliage for oil, or sap then the landuse=forest is suitable.

The landuse does not have to constantly be updated with the planting, growth, harvest and fallow cycles .. that is implicit in that use. In the same way a farm field is not constantly updated with the planting, growth, harvest and fallow cycles.

@BushmanK ? landuse=logging ! Really! That is another ‘bad tag’. It describes an activity .. not a use.

Adding unknown roads using ImproveOSM

Hi, I know one mapmaker who uses the speed of the vehicles along a road to gauge the road type/condition … it may be possible to do the same here by comparing the gps speed to other roads in the area.

#journey with josm

The usual teach process is to start with the simplest easiest to understand tool and, as the student progresses to introduce them to a more complex tool .. finally to introduce them to the most complex tool

Having been subjected to this process over many years I now chose the most complex tool to learn first .. saves a lot of learning things that I later have no use for.

Uploaded three tracks , my first ever , please let me know what could have been done better

If you want comments on a particular change you made .. then you will have to identify the change you made .. usually this will be made by a particular ‘changeset’ number 37965957 e.g. full link changeset/37965957#map=14/51.1446/4.4387

Where a changeset has multiple charges then you could identify the node/way/relation, say way/181345107

e.g. full link way/181345107

The difference between the novice and the expert?

Knowledge.

Within OSM the novice mapper can know far more about their local area than the most experienced mapper, so both are valued to the same degree. The novice mapper has access to the same level of mapping tools as the experienced mapper, the novice mapper usually does not know of there existence due to the vast number of tools available and the number of features of these tools. Some of these tools are turned off by default and ‘hidden’ behind options to ‘help’ the novice avoid common mistakes.

Both are human and make mistakes, the novice mappers errors are usually small, having little impact on the total map, and easy to fix. The experienced mappers errors can be subtle, harder to find, and much harder to ‘fix’.

What shall we have for diner tonight?

@BushmanK “The situation with grass doesn’t deserve to be changed since there are multiple unclear views on the same tags.”

??? I’d think that would be a very good reason to clarify exactly what it is. In this case it is just “grass”. And “grass” is a landcover. What it gets used for is a different tag and if needed that should be tagged … but landuse=grass makes no sense which is why it needs to be changed and why it gets used for lots of things. To me the case of “wood=coniferous” andleaf_cycle=evergreen” is less clear.
