Wochennotiz-kritik #332

Posted by MKnight on 1 December 2016 in German (Deutsch)

das wird (wahrscheinlich) eine Reihe an Kommentaren zu Themen aus der Wochennotiz. Ich sehe das zu diesem Zeitpunkt nicht direkt als Kritik an der Wochennotiz oder an den ausgewählten Themen (also nicht wie bei meinem letzten Eintrag, wo die (und ich) grandios auf einen wirklich begnadeten Troll und Schwätzer reingefallen sind), sondern eher eine Zusammenfassung, der (verlinkten) Dinge, die man eigentlich besser machen könnte.

  • es gibt einen malenki-task: http://tareas.openstreetmap.es/project/38 ich dachte: ok, das is was wirklich Feines, um Trauer oder Wut zu verarbeiten, da hab ich Bock drauf. Leider kann ich in Josm das WMS (edit: Lösung: es ist ein TMS, siehe) nicht einbinden, also mappe ich nicht, sondern devalidiere nach Bing diverse Tasks. Etwa eine Stunde später hab ich keinen richtigen Bock mehr, weil das wieder wie bei HOT läuft: so viele Kästchen wie nur möglich begrünen, aber die Aufgabe nicht gelesen:

    Zu mappende Objekte All things you can see on the map

Ähnliches Thema hatte ich schonmal hier.

(sagte ich schonmal, dass markdown scheisse ist?)

  • "Martijn van Exel schlägt vor, gemappte vorübergehende Sachverhalte mit dem fixme-Tag zu versehen, um sicherzustellen, dass sie nach ihrem Wegfall entsprechend geändert werden."

Von der Idee garnich so schlecht, nur sollte man sich vorher mal anschauen, wie alt fixmes im Durchschnitt sind und wie oft die gefixt werden. Grob übern Daumen und nur leicht übertrieben: nie. Sicherstellen is was anderes.

Kritik direkt an der WN hätte ich allerdings auch noch: früher™ wurden fremdsprachige Links offensiver gekennzeichnet. In der aktuellen gar nicht.

Clean up the "fixme's" around you!

Posted by marczoutendijk on 30 November 2016 in English (English)

The fixme=* tag is often used to give other mappers an indication that something needs more research (or it is a "note to self") .
All too often it stays at that point and no one ever cares any more about such a request for improvement. I found out that roughly more than half of the fixme's is at least 2 years old.

I wrote a simple overpass query with some stylesheets attached which shows the text of the fixme immediately on the map.
Click on the link above, locate the map to your neighbourhood and hit the run button.
Is there something you can fix? Please do so and remove the "fixme"

For the centre of London, this is the result:

The overpass query searches for nodes with a fixme=, but you can easily change it to finding ways instead.
And if you want to locate all note= tagging, simply replace "fixme" with "note" in the script.

Street Art

Posted by alexkemp on 30 November 2016 in English (English)

Continuing to work my way through the Phoenix Farm Estate today, catching up in late-afternoon, with a late-Autumn sun low on the horizon at England's high latitude & damn cold, on houses missed on Stanhope Road. And yes, it turns out that there used to be a “Phoenix Farm”, though I have zero hard information on that to date.

Regular readers will realise that I constantly seek to alleviate the boredom of collecting endless lists of house numbers by spotting & photographing good examples of art on the houses that I pass ([1] [2] [3] [4] [5] [6] [7] [8]). Here is the latest: –

Phoenix is actually the next estate and not the current one.

Online-Karten (Slippy Maps): meine Favoriten

Posted by g0ldfish on 30 November 2016 in German (Deutsch)

Fasziniert von Karten bin ich ungefähr, so lange ich denken kann. Mein Freund ist immer von Tafeln mit historischen Erläuterungen magisch angezogen, ich dagegen komme an keiner Karte vorbei, ob gedruckt oder online.

Außer der zauberhaften, wenn auch für manche Zwecke eher ungeeigneten Aquarell-Karte von Stamen (http://maps.stamen.com/watercolor/) habe ich noch einen absoluten Favoriten:

http://www.opentopomaps.org/

Ja, ein bisschen altmodisch vielleicht, aber ich stehe dazu.

Schade finde ich nur, dass es schwierig ist, sinnvoll beizutragen. Keine Spenden und offenbar wenig "niedere Hilfsarbeiten" zu erledigen, für die man kein Entwickler sein muss.

Die Garmin-Karte von Opentopomap muss ich unbedingt auch mal testen, falls ich mein altes Gerät wieder lauffähig bekomme.

Thanking you

Mapping my home town : Gobichettipalayam

Posted by Fa7C0N on 30 November 2016 in English (English)

Gobichettipalayam is the second largest urban city in Erode district, Tamilnadu, India. It is known for the green rice fields, because of that many Tamil movies were shot here. It is in human nature to start any task from a place you already know, since I was born and brought up in this town I started my mapping here.

Quality of map before mapping:

Alt most of the roads were traced

When I started mapping most of the roads in Northern part of my town was already mapped, but some roads are named wrong. In case of POIs, there is little to no information on the map and most of the schools, Banks, Petrol pumps, community centres were not mapped. So I planned to proceed by matching the road density in the southern part of my town to the northern part and then concentrate on adding the POIs.

Things I mapped:

  1. I started by adding major and minor roads in the southern part of my town with the help of OpenStreetMap wiki for tags while correcting some road names in the northern part.

  2. Then I mapped POIs like Banks, ATMs, Schools, community centers, government offices, petrol pumps, Department stores etc., that I am sure of its location.

  3. After this I moved on to adding addition informations like bridges, bus stops and farmlands.

Quality of map after mapping:

Future plans:

  1. Adding road names.

  2. Map the missing buildings along with addresses.

  3. Add all the missing POIs.

Continued Work Around Our Hill

Posted by DesertTrip on 30 November 2016 in English (English)

I found another misplaced overlay of streets in the wrong area and deleted them. Corrected names of streets, deleted non-existent streets and tomorrow will drive around to confirm streets (and their order) before doing those such as the little courts off Cedral.

Weather Underground (aka Wunderground) wrote me today to confirm that they did just recently switch to using OpenStreetMaps for their personal weather station maps. When I am done cleaning up my area, I will go across the big road and clean-up the area for the 3rd weather station in our area.

Oh yeah!! Once I get the confirmation of our hill name from USGS, I will be adding it's name as well. We sent the name proposal to the USGS in 2014. It has since been sent to our state, then to our county, back to the state (all approved) and is just waiting for it's finalization at the federal level. I was told it should be finalized within the next 30 days. Our nameless hill (which is a distinguishable landmark from afar) will finally have a name. I can't wait! That will be fun to be able to enter. Kind of like the dessert after all this road clean-up.

Raster map tiles for Mapillary traces

Posted by Peter Bremer on 29 November 2016 in English (English)

Today, Mapillary released a set of online raster tiles that show all traces (and if you zoom in enough, all individual photo locations). The tiles are transparent PNGs, and can be used on top of other map layers.

The tileset address is https://d6a1v2w10ny40.cloudfront.net/v0.1/{z}/{x}/{y}.png

Note that various mapping software use different formatting for the x, y and z parameters. For example, OsmAnd uses {0}/{1}/{2}.

A demo page is available at http://mm.mapillary.io/raster_tiles.html

For more information, see this Mapillary GitHub issue. Also for reporting problems with the tileset, please use their GitHub repository.

OsmAnd

Here are some step-by-step instructions to add the tileset to OsmAnd. This way you can have a map showing all Mapillary traces with you on your phone, even offline if you cache the tiles before the trip.

  1. Go into "Configure map" (either from the menu, or from the globe icon).
  2. Select "Map source".
  3. Select "Define/Edit" to define a new map layer.
  4. Name it something like "Mapillary traces", and as URL enter "https://d6a1v2w10ny40.cloudfront.net/v0.1/{0}/{1}/{2}.png".
  5. Click "Save" to save the new map.
  6. Now, back in the "Configure map" screen, select your new map as the "Overlay map", and select an opaque map as the "Map source".

My Area Needed a Lot of Work

Posted by DesertTrip on 29 November 2016 in English (English)

It appears people are using some overlay and just copying it. I live here. They are wrong. There was literally 4 or 5 duplicates of our roads all within a mile or two. Some going east-west and some north-south. Some even diagonally through houses! Several duplicates went straight through mountains. MANY roads were misnamed.

I do hope that people double check before editing in the future.

Go look at what the county GIS maps show!!! Go look at your own street signs. Just don't trust the overlay here. It is WRONG.

I still have many many hours of work to do on my area. This is NUTS.

Towers and Masts

Posted by BushmanK on 29 November 2016 in English (English)

Browsing through the issues at Openstreetmap-carto (also known as OSM Standard style or "Mapnik" style) tracker on GitHub, I came across several issues, both open and closed, touching the topic of rendering vertical man-made structures such as poles, masts, and towers.

Communication engineering was my thing for awhile, so it always strikes me when at least two of these terms - mast and tower - are used in an uncertain manner. In one of the discussions on GitHub, the difference between masts and towers was called "philosophical". Actually, there is no philosophy (at least if you don't look at wrong and misleading examples in OSM Wiki). Because of that, I've added an engineering definition to pages of man_made=tower and man_made=mast both in English and Russian because what is in the first section of those pages makes zero sense and contradicts the basic principles of tagging, because it uses comparative terms such as "bigger" and "smaller" to distinguish between these structures. Tags tower:construction=guyed* are obviously redundant because if you need that, it means that object must be tagged as a mast, not as a tower.

I didn't want to rewrite the whole "definition" without discussing it, while I don't really believe that discussion could be successful, so I just added clear definition in case if someone would prefer it. Just for the reference:

Mast is a vertical man-made structure, supported by the guy lines and the anchoring system.

Tower is a vertical free-standing man-made structure, supported by its own foundation only.

(Anyone can find it even in Wikipedia, so it makes me wondering, how ignorant an author of these OSM Wiki articles was to write that.)

And it doesn't matter, that some contractors (and regular people after them) calling cellular communication towers "masts". It is not only wrong as it is to use "transistor" to call a radio receiver or "Xerox" to call a copy machine (which is common in some languages), but it makes it impossible to actually distinguish masts from towers for mapping purposes.

So, getting back to rendering, both "inverted T" and "inverted Y" are completely appropriate for tower symbols. Inverted T looks like a tower with a single stem or column, standing on its foundation, tower:construction=freestanding. Inverted Y looks more like a rough outline of a steel lattice tower (more strokes could be added to make it look fancier), tower:construction=lattice.

Masts are a bit more tricky, but just a bit. The most obvious symbol is an "inverted bird foot" symbol, similar to inverted Y with the central stroke, extended all the way to the bottom. It also looks like an inverted antenna symbol used for circuit diagrams. Central stroke represents the mast itself, diagonal strokes represent guy lines.

As a bottom line, rendering of masts and towers is not solely a question of style and preferred icons, it's also a question of using proper definitions. If definitions will get clarified one day, no philosophy will be involved in rendering and tagging anymore. (Personally, I really doubt that it will happen.)

Added from comments: These tags currently do not have "OSM-specific meaning", they are completely mixed into one mess - it is technically impossible to be sure if an object, tagged with man_made=mast is a mast and vice versa. So, changing anything can't do any harm, because it can't be messed up more than it currently is.

People are arguing about that only because almost every person has an own tradition of tagging and thinks that all others have a similar one. But it's not true - different objects are tagged similarly by different people as well as similar objects are tagged differently by them. Belief, that there is any global consistency in tagging masts and towers is just a fallacy.

Good Garden Sheds

Posted by alexkemp on 28 November 2016 in English (English)

The chap that I saw on Phoenix Farm Estate yesterday (Sunday 27 November) could not believe that I thought that his shed was worth a photo. My reasons were simple: partly it was the quality of the build: Google StreetView is October 2014 & shows a very nondescript garage, whilst the modern shed+garage is very smart. However, the reason that clinched it for me was the name that he had put upon the door of the shed next to the garage:

“The Man Cave”

Good Gardens

Posted by alexkemp on 28 November 2016 in English (English)

There are some gardens that I come across whilst mapping that simply cry out to be featured in these Diary pages. There are two today, both located on an unadopted road (the householders have to pay for all road upkeep) in Gedling that I first walked on Wednesday 23 November on a truly dreadful day. The rain was interfering with the smartphone's capacitative action, so I went back on last Sunday 27 November.

The first garden below is included simply because I found it sweet (and why not?):

aaah!

The next seemed to epitomise water action. It was pouring down from above and even flowing in a culvert below, so it seemed only fair to have galleons in a pond as well:
