Street Art: Bill & Ben + a Silver Salamander

Posted by alexkemp on 16 June 2016 in English (English)

You will need to be of a certain age & British before the words “Bill & Ben” or The Flowerpot Men mean anything to you (both of those caveats ring true for me). In this next bit of garden/street art, the home owner in Highfield Drive, Carlton has decided that they prefer Little Weed to Bill & Ben:—

2 Little Weed

The final example of house/street art is from Standhill Avenue, Carlton and, as a silver salamander, is very different to Bill & Ben:—

These were both shot whilst I was surveying Carlton, England in the same Wednesday 15 June afternoon. There was the kind of steady drizzle that is capable of soaking you to the skin in minutes. I gave up after an hour or two, partly because I became convinced that my mobile might short-circuit. Hopefully the pics above will cheer you up as much as they did me.

National Park Rendering Issue

Posted by Sunfishtommy on 16 June 2016 in English (English)

So I have been going on a mapping spree lately mapping the outer banks of North Carolina, but What I have begun to notice is the national park boundaries are covering up all the detail out there. Many parts of islands are simply specifically their coastlines, are covered with these giant green blobs called National Parks. Here is an example at Portsmouth Island

What is even more frustrating, is this rendering issue has already been solved, when looking at lakes around borders of national parks, we see the green get covered by the water, with only a green shaded line remaining above the water to represent the border of the national park. Here is an example at Fontana Lake. Is there anyway we can fix this, It seems like a simple fix, just get national parks over oceans to render the same way as national parks over lakes.

Is there any reason this cant be done?

I have thought of a couple work arounds, like making the border of the national parks the islands, or putting an area of water over the area affected by the green blob issue, so it would be rendered correctly, but I realized that this would be mapping for the render which is a no no.

So how do we get this fixed?

Edit: I think I found the problem, For some reason many of the national parks are labeled with the tag leisure=park. the wiki page clearly says this is not the appropriate way to tag National parks. The solution seems to be to go through and remove the tag leisue=park, which will fix the rendering issue, as well as follow best practices.

Google Summer of Code 2016 - improving openstreetmap-carto

Posted by Mateusz Konieczny on 14 June 2016 in English (English)

During GSoC 2015 I focused on improving road presentation in the Default OSM map style. This year I am again participating, but with more diverse goals. I am planning to improve performance, reduce rendering order problems and tune mid-zoom level rendering.

mid-zoom level rendering

I started with work on improvements to mid zoomlevels (z6 to z9). During search for the best and most promising ways to improve rendering, starting from trawling through reported issues. I also prepared and submitted some additional tweaks like rendering names for barriers, fixing viewpoints and forests and shops and other.

I am also like during GSoC 2015 preparing a comparison between the current map style and alternatives.

A bit of history

There are some visualisations showing how data was added to OSM. But I have neither seen nor found something similar for a map style. So, for start of next big series to the map I made a display of what was changed in the past.

Visualisation are available for z18 z18

z14 z14

z8 z8.

I selected Weybridge as location as map of this place was the first OpenStreetMap-based map to go on Wikipedia.


As usually testing and review is welcomed for open pull requests, especially one considering rendering names for barriers and an associated popular tagging mistake.

I am considering to look more for inspiration/comparison in printed maps. I looked for online sources and for now I found surprisingly small number of contemporary maps that would display sort-of-similar set of symbols as Default OSM style, with scale within z5 - z10 range.

From promising findings I caught David Rumsey Map Collection and Wikimedia Commons (enabling CCI allowed to find something).

But I found nothing highly useful. For now

are the best. Is anybody aware about maps or database of maps allowing to find maps similar in content to Default OSM Style, with scale within z5 - z10 range?


Thanks to Paul Norman for simplified osm2pgsql database dump. Without that resource obtaining database for lower zoom levels would be far more complicated.

Street Art

Posted by alexkemp on 14 June 2016 in English (English)

The streets & civic boundaries (though not Parish/Ecumenical boundaries) are well sorted for Nottingham & district; well done SK53 & will_p for a fantastic amount of effort to create that (at least in my neck of the woods). That prior work occasionally needs a small trim here or there, but mostly my survey work is to add house number/names. It is useful exercise & gets me out of the house, but can be very boring. Fortunately, Nottingham folk are house-proud, love their gardens & are naturally creative, and spotting the results all helps to keep me awake. Here are some more examples from Standhill Road, Gedling:—

As I understand it, it was british Victorians that began to name their terraces as “Villas”, and to often include the start-date. There are good examples of this in a little terrace of 5 houses; I especially love the ‘bird's nest’ below the number for Hazel Villa:

hazel villa

...but it's the owner of Vivian Villa that has really gone to town with the pot plants:

vivian villa

Interestingly, Gedling Council itself takes pride in being creative. This is the sign for the King George V Recreation Ground + some of the sequence of photos (Mapillary seems to be having difficulty in processing them):

King George V Recreation Ground sign

King George V Recreation Ground

According to this page the recreation ground is within an extension of the Thorneywood Brickworks and, further, that there used to be a tunnel under Standhill Road linking the two clayworks.

In the following 1938 picture (also in the 5 June diary) the recreation ground is at the top right-hand side, and Standhill Road can be seen running across the spur of land that remains between the two sets of clay workings:

Meanwhile, this Gedling Council Street-Guide PDF may be interesting to some, and especially due to the inclusion of a map. The map is copyright Ordinance Survey (of course), but I thought it a good contrast & compare to what OSM can do.

In a final coda, at the extreme top of Standhill Road is Porchester Junior School (the school urgently wants someone as a School Crossing Patrol person for Prospect Road if you live local) and, at the back of the school on Hillview Road, is number 61 on a plot of land that (a neighbour informed me) used to be “Sanders Farm”. So far, I can find zero information to confirm that assertion.

A tyro's experience with OSM

Posted by upendrakarukonda on 14 June 2016 in English (English)

As we all are aware of that working in the open community will always give the feeling as working with family, where we can express our views , ideas and experiences. As an enthusiastic mapper, I just want to share my experience of working with OSM & JOSM. Though I have experience with mapping , but I’m green horn to this OSM. So I have started to learn everything about the OSM. Open street map is a user friendly website ,where we can contribute our mapping skills to map our home town or any place based on the knowledge of particular place. That is the basic environment, where the simple tools are designed to work and map the buildings, roads etc. These tools are more flexible in nature and bit interesting to work. There are also video tutorials and notes that helps us to get inhabit with the OSM. These tutorials helps us to understand basic techniques of mapping in the OSM. The mapping in OSM in an voluntary act where our mappings will helps some people around the world. It is directly used by the users. So every mapper should be careful while mapping. There should be no scope for errors. So I too mapped some area in my home town which is familiar to me through OSM. I am also attaching the work on my home town as well.As life is all about series of excitements, which you have to taste each and everything, I have come across the working on OSM with JOSM. Surely I can say that it’s best part of my learning career. After a long time I really felt challenging and exciting working with JOSM. It took nearly four days for understanding the each and every aspect in the software. Right from installation part to uploading process, I thoroughly enjoyed working the JOSM. It was software with great and user friendly interface. I had referred many sites and links for the working on JOSM. Gone through many videos for the procedure of mapping using JOSM. I was really fascinated by the filter option which is very interesting. Felt that there should be more snap shots and videos on the splitting process and also tagging. Really it was a great experience from working with JOSM. Its robust nature and shortcuts for many tools makes mapping more comfortable and interesting.

Out of Town Experiences

Posted by alexkemp on 12 June 2016 in English (English)

Thursday, on a blistering 9 June (followed up by thunderstorms on the weekend, which is classic weather for England) and I finally get to do some surveying out of my Home patch.

My Home patch is Nottingham NG3 – just a kilometre from the town centre – and everything that I've surveyed so far has been more-or-less well known to me. Now, finally, I get to the end of that patch. Here is the proof, with the 1877 Borough of Nottingham Boundary Marker outside the Peacock Health Centre where Carlton Road becomes Carlton Hill (it is also a node on the map, but I do not know how to discover what the node-number is):—

1877 Borough of Nottingham Boundary Marker

This is where Nottingham becomes Gedling, and also where the NG3 postal-district becomes NG4.

My first houses were Carlton Hill & Standhill Road. I'm going to keep surveying the houses west across the hill & to the other side. I'm interested to see what I will find.

In the meantime, I'm always interested to spot the art that folks put on, or in front of, their houses. Below is a little example from a house on Standhill Road:—

This week one of the OSM mappers will be a lucky one:
he/she will find out that the 40 000 000th changeset carries her/his name!
Will there be a party?

At the moment I post this, there are some 30 000 changesets to go!

Unrendered elements

Posted by Nikola Bura on 12 June 2016 in English (English)

Is there anything that can be done about un-rendered elements? For many OSM features, the data is there, but it doesn't get rendered on the map.

As far as I can tell, this happens with:

  • All the Offices
  • Many Man-Made nodes: like Sirens, Tanks, and Pipelines
  • Parking Entrance nodes
  • Flagpoles

Can we do anything to fix this? I understand why unimportant features like sirens, flagpoles, and pipelines would be removed; but things like Offices and Parking Entrances seem rather significant.

(This is my first time posting, I hope I haven't broken any rules...)

Gotta love people who don't look at the satillte imagery and ajacent ways and think that turn lanes need to be fixed. :/

Posted by rickmastfan67 on 10 June 2016 in English (English)

Cases in point: &

Both people on took out the 'none' from the "turn:lanes:backward" tag. From "none;slight_right", to "slight_right". Now the info for that section is completely WRONG. The 'none' is there to indicate that the road there is splitting into two lanes. With taking out the 'none' part, it indicates that there's only one direction the lane is going. Here we have them removing the 'none' from beside the 'slight_left' indicating there's a new left lane starting.

Gotta just love who think everything is an error........ 'none' is a VALID tag for turn lanes for crying out loud!!


Missing House Numbers, and missing Parish Boundaries

Posted by alexkemp on 10 June 2016 in English (English)

Whilst surveying on Florence Road last Sunday 5 June, I finally began to get some answers to a perennial question that has come up ever since I began surveying for OSM back in March of this year:—

“Why is that house number missing?”

Now, this may never affect you and, if so, I congratulate you on your mental stability. For myself, years of computer programming have deepened my natural state. Something like the situation in Florence Road can create the equivalent of a mental itch that I cannot scratch that can last for days or weeks, months or years...

The house numbers in Florence Road flow naturally from Porchester Road to Hillview Road; even numbers on the south-side, odd numbers on the north-side. There are additions here and there (‘48’ & ‘48a’, ‘19’ & ‘19a’) and some “teeth” missing (only a gap between numbers 20 & 26), but what causes me to stare hard is number 43, which has 45 on the up side (no problems there) and 39 on the down side. What has happened to 41! Whilst contemplating this, the lady owner pulled up in her car & gave me the answer.

Florence Road was originally part of the Earl of Carnarvon's estate, and was divided out into Allotment plots + sold off for houses. Her house was built on 2 adjacent plots (thus originally designated for 2 houses but only the one actually built). She also mentioned that the nearby Punch Bowl was originally the Earl of Carnarvon's Estate House and, in so doing, transferred all of my original itch (missing house number) to “Earl of Carnarvon”. Who he?

The Earl of Carnarvon has the full title: “Earl of the Town and County of Carnarvon, in the Principality of Wales” and, to save bitter comments, the town & county are more commonly spelt “Caernarfon” these days. It is the 3ʳᵈ creation of the title (the male line died out with the first two; 3ʳᵈ time lucky, eh?). The 1ˢᵗ Earl was Henry Herbert and, in 1793 when elevated to that Peerage, was already 1ˢᵗ Baron Porchester (“Baron Porchester, of High Clere in the County of Southampton”, in 1780). The family tradition then became that the Porchester title was adopted by the son of the new Earl at his ascension (in other words, at the old Earl's death).

That is supposed as the original source for both the name of the road & for Porchester Gardens. If you look at the West-side boundary of that link you will see (what used to be) the entire length of the original “Porchester Road” (it is now called that all the way down to Carlton Road, but the length from Carlton Road to Daisy Road was originally called “Thorneywood Lane”).

Let's have some pictures before any more verbiage. Here's an announcement of Porchester Gardens at the head of Kent Road where it meets Porchester Road:

Porchester Gardens

The following certainly seems to prove the assertion about the Punchbowl (this is the gatepost for foot traffic to the Punch Bowl at Daisy Road/Porchester Road):

Punchbowl Gatepost

The Porchester St James History page states that “Porchester does not appear on maps of Nottingham as a place” (they are talking here of the church Parish of Porchester). Sadly, that still rings true for OSM. As best as I can tell, OSM does not have any Parish boundaries, or even Diocesan boundaries, which seems quite astonishing.

To be clear, we are not talking administrative nor urban boundaries here. That can be made very clear by comparing the admin boundary of Gedling, which can easily be found on the OSM map, with the Parish Boundary of Gedling using Parish Finder. Often the civil & ecumenical boundaries will be the same, but not all the time.

I'm actually very surprised that some church group hasn't spotted this & taken ownership of putting themselves up on OSM at some point in the last 12 years. Parish Finder uses Google Maps; I assume therefore that they are paying Google for the privilege.

Using Parish Finder we see that part of Porchester Gardens (rather strangely) is within the Nottingham St Jude Parish, whilst the rest is within Porchester Parish. This latter includes many of the streets that I've been surveying recently, and runs up the centre of the very interesting Donkey Step. All of these parishes are within the Diocese of Southwell and Nottingham.

The Porchester History page cites the Earl of Kingston to have owned this neck of the woods due to his action in enclosing Marshall Hill in 1672 (and indeed much more, since he is also cited as owner of the Thoresby Estates). Now, you will understand that I am employing the original politically-correct language of those times when I use the word “enclosed”. In my native Yorkshire we tend to call theft by it's correct word, but of course the self-declared nobility have been stealing the common land ever since William the Bastard robbed, raped, murdered & burnt his way through these lands in 1066.

Now, as best as I can tell that is Evelyn Pierrepont, 1ˢᵗ Duke of Kingston-upon-Hull (1715), 5ᵗʰ Earl of Kingston-upon-Hull (1690) & Marquess of Dorchester (1706). He was succeeded by his grandson (same name, 2ⁿᵈ Duke) and his sister became Lady Frances Medows; we have a direct line of descent from her down to Catherine, Duchess of Cambridge.

The second son of Lady Frances Medows was Charles Medows, Earl Manvers (title awarded 1806). He had become Baron Pierrepont, of Holme Pierrepont in the County of Nottingham (1788) and Viscount Newark, of Newark-on-Trent in the County of Nottingham (1796). Charles had inherited Gedling through his family, and it was he that cleared Marshall Hill for farmland, and established Marshall Hill Farm. The whole of the farm estate was bought by the Earl of Carnarvon (the 5ᵗʰ Earl is the best well-known, for discovering the tomb of Tutankhamun along with Howard Carter).

Marshall Hill is missing from the OSM map (only the ancient Bartholomew 1897-1907 map shows it). Westdale Lane West runs along the top of that hill, whilst Marshall Hill Drive climbs the hill & joins with Westdale Lane at the top.

Finally, and after much preparation, I can now sketch out how the land became available for building plots.

In 1887 the locality was entirely rural except for the Lunatic Asylum, built in 1880 on the other side of Porchester Road (more info in Nottingham Suburban Railway, Part 2). The Nottingham Corporation had dispossessed some folks of their allotments in order to build the Asylum. Those folks approached Samuel Robinson, Charles Bennett (of the NSR) and David Whittingham, who together agreed to act as guarantors so that they could continue to work some gardens. 6 acres (0.024 km²) were purchased from Earl Carnarvon on 26 March 1887 at the corner between Woodborough Road and Porchester Road. It became the start of Porchester Gardens.

Two things happened now:

  1. Victorian Nottingham folk were mad-keen on allotments & gardening
  2. They decided in the end that the best rewards come from growing houses

The original 6 acres swelled to about 250 acres (1 km²). The first house was in 1889, but the true spurt in building followed after the Great War in the 1920s & 1930s. Roads and mains water were laid and gardening allotments were converted to building plots. The suburbs had arrived.

Survival Techniques for Hot Weather in Carlton

Posted by alexkemp on 9 June 2016 in English (English)

In the fewest possible words:—

  1. Clothes — keep covered from the heat with cottons/silks
  2. Hydration — small, continuous drinks of water
  3. Salt ‘n’ sugar — water is not enough
    (surprise: Coke/Pepsi are ideal, if expensive & burpy)

It is currently 21:25, 20℃ & 68% humidity in Nottingham. It was far, far hotter whilst surveying this afternoon on Carlton Hill, and I was struggling to keep my head intact (losing too much salt via sweating).

The message about hydration seems to have got through to the young, but I'm not sure if the message on electrolytics (salt) has. Here is a tale from the 1970s; it was sufficiently dramatic that I learnt it for ever.

I was in my 20s, married with a young child, and the collapse in the value of the £ (GBP) + soaring inflation had meant that my so-called good job would no longer pay the mortgage. I found another job. That saw me canvassing for lemonade sales door-to-door 10am-4pm at this time of year in similar weather. I was guzzling lemonade throughout the day at an astonishing rate of knots.

The residential estate I was working was at the top of a hill, so the route home was downhill all the way. The vehicle I was driving was a Commer van, heavy in itself and still loaded up with crates of lemonade. My first intimation that I was not in a fit state to drive was when I drove smack into the back of a car parked at the side of the road.

I knew it was there, but had become transfixed at the wheel and my reactions were so slow that I hardly diverted away from the vehicle. The back of the car was written off, the Commer van was barely scratched. The folks that owned the car had just loaded it up ready to set off on holiday. Thankfully, no-one was hurt; just bent metal & disappointed dreams.

There is a curious connection between what happened to me & what can kill young kids in hot countries such as Africa that catch dysentery. The root cause is often a bacterial or amoebic infection, but the actual danger is dehydration & consequent loss of minerals & salts. The rehydration therapy is NOT just water; the early doctors that tried to help discovered that children still died if they only got water. Aid workers now carry plastic bags that contain a dry mixture of sugar & salt. Mixed with boiled water, that becomes the life-saver:—

6 level teaspoons (25.2 grams) of sugar
0.5 teaspoon (2.1 grams) of salt
1 litre of water

...and here is a further curiosity for you: original Coca Cola & Pepsi each have the exact mixture of salts to water as shown above.

68% humidity is very low for England. Nottingham is in the middle of the country, yet is only about 75 miles (120km) from the sea. 90% humidity is typical here, if not higher! However, every so often we get an influx of weather from the Sahara, the humidity plummets & kidney stone incidents soar.
