Mapping lake shore

If your using JOSM there is a plugin called scan aerial that may help to start mapping the crinkly bits.

Walking the Bounds: Bassetlaw

I agree … except some admin boundaries (a legal or social feature) are in part physical features.

Example: Part of the boundary between the Australian states of NSW and Victoria is the Murray River, actually not the river center but one edge (I forget which gets the river itself). So there are some exceptions.

Wood … I have come to the firm conclusion that this should not be associated with boundaries of parks etc … it should be its own way/relation. In fact, I think, in most cases, any ‘natural’ (landcover or landform) feature should not be part of any other feature.

So … as a guide … one feature = one OSM entity

There is a difficulty where two features coincide or nearly so - the editors are set up to snap to nearby nodes .. so the nodes get shared between the two ways/entities. There are ways around this .. but if your not carefull then it happens.

Latest Spam

Most spammers will; not have any edits … only make the one dairy entry …

Human moderation of the first post would probably get most of them … but in terms of work/benefit in OSM ?

I Ask for a #3 Buzzcut & This is What I Got!

That would not be landuse=forest but natural=wood :) unless the harvest is used for making wigs, brushes … :)) Humm I wonder if hairdressers make something on the side recycling the ‘waste’? Not something the younger productive (hair wise) people would think of…

Deriving centerlines from riverbanks without.

While a mapper may take the ‘center line’ of a river to be a geometric mean of the river banks boats and ships will probably prefer to take it as the deepest part of the river for navigational safety purposes and if the river ever gets low then this will still be the rivers center line.

So .. include a source statement of your ‘center-line’. And refrain from changing one already entered unless you know the intention/source of that center line.

Route numbering in Angola

It is not so much about some ‘standard’ that has official backing… but what exists for the people. So if there is a route marking on a sign .. use that. It is what the user will see and be able to relate from the map to what is there, that is the important bit. If the route shield/design changes along the route .. then so be it - have separate relations, even if it is the same route number.

If these routes don’t have any visual clues on the ground .. then are they worth mapping? By all means map the roads and their local signs … but don’t spend time chasing stuff that only exists as a planers dream.

Does that help?

Some of them get removed. Relax. let ‘them’ (who ever ‘they’ are) deal with it. Best to just ignore them and concentrate on the good stuff. If the firm is local I might just go for a visit and voice my disgust in person, only had one of those and it was not OSM related.

Why Search and Rescue Organizations Must Map Out Cellular Phone Towers in OpenStreetMap

Oh, cell phone coverage in Australia is claimed to cover over 90% …of the population. This is less than 10% of the area. Reliance on cell phones for emergencies … no. You want something simple, that works anywhere and is reliable. A paper map, a compass work without batteries. An EPIRB/PLB are serviceable for many years and work most places (need a view of the sky).

Why Search and Rescue Organizations Must Map Out Cellular Phone Towers in OpenStreetMap

Country and area specific.

For international use 112 is the emergency number for cell phones.. should even work in the states!

Things other than cell phones should be considered for remote emergency use - satellite phones, EPIRBS (or PLBs), SPOT etc.

In some places water is much more important than a weapon.

Homemade Mapillary Hood Mount

People have been fined for mounting small cameras on the outside of their car in Australia. Reason being given is that they pose a hazard for any pedestrian that may get hit. I take it you have no problem with the fighting kites? Take care.

Old Satellite Imagery of the Philippines

The satellite imagery used depends somewhat on the zoom level you are using. With a diameter of 300 kilometers you get low resolution suitable to pick out oceans, large forests … zoom in to say a 1 kilometer diameter to look for houses …

OS Benchmarks

I have used man_made=survey_mark for similar things .. See http://www.lpi.nsw.gov.au/__data/assets/pdf_file/0020/208280/Protecting_survey_marks.pdf for some different kinds of survey marks.

See https://help.openstreetmap.org/questions/44030/how-should-we-tag-ordnance-survey-bench-marks for more comments..

Some of these have become tourist attractions! These have been mounted on concrete plinths … however some have been stolen, vandalized … the more popular ones have had ‘tourist marks’ placed a little way off the actual survey mark and the true survey mark hidden in some way.

House Numbers & Street Names

In ‘outback’ Australia ‘stations’ (a farming property with a central concentration of buildings one of which forms the main residence) have names that are in common usage. They may have a property lot number and possibly the post office may allocate a reference number, but everyone uses the name. The remoter properties get their mail weekly .. by aeroplane. It is still common practice to have the name painted in large letters on the roof to aid navigation by aeroplane.

In the early days of Australian settlement houses had names .. these too were in common use and numbers were little used. Modern practice is to only have a number.. a lost cultural practice.

My Very Own “Middle-Class ‘Paranoid Guy’”

I expect there are a few of them. Maybe they should be mapped? Like landmines and speed cameras? That way you might be able to set up a proximity alarm on a GPS when you get close.

Well Done Tesco!

A quite place to have a break can be hard to find. As well as parks .. cemeteries can be good, tend to lack toilets. Humm do Tescos have public toilets?

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.
