New road style for the Default map style - the second version

Posted by Mateusz Konieczny on 23 July 2015 in English (English)

"map styles: Default OSM vs Google Maps" included comparison of OSM Default map and Google maps. Now I present a similar comparison at the same location. But now with a third version - current version of new potential road style.

From left: (1) with changes developed as part of road redesign (2) currently used rendering on OSM website (3) Google maps

Maybe it would be a good idea to make landuse=residential darker on low zoom levels to better mark built up areas, but overall I consider this change as significant improvement.

Changes based on feedback:

Thanks to daganzdaanda for the idea of displaying highway=tertiary as white line, wider than highway=residential/unclassified. As tertiary roads are no longer using yellow it made possible to display secondaries using this color, what it turn allowed to move hue of primary toward yellow.

It was not simple as it sounds. For example, one of obvious consequences is that yellow roads are now rendered also on lower zoom levels. It is problem because the yellow roads are hard to keep visible both on landuse=farmland and unmapped land. For example using light yellow worked great on farmland but completely failed on unmapped land where it was really hard to notice.

Making highway=primary yellower allowed to render trunk in orange and keep road classes possible to differentiate.

So: highway=trunk and highway=motorway are now rendered differently.

See for example highway=trunk near Košice and D1 motorway.

and now with the new style. Game "spot highway=trunk" is now less challenging and it should be distinguishable from motorway.

And view at the preview location from readme

Using a grained fill pattern to indicate unpaved roads is an interesting idea that will be tested. I will also test idea of using dashed casing for unpaved roads with tunnels marked solely by colour change of fill and casing. There was also idea of displaying tunnels as without fill what is also worth testing - but it is likely that displaying unpaved roads as one with dashed casing and fill would be too close. Also, size of ref shields should be reconsidered - it seems possible to make them small without losing readability.

railways

There are also changes to how railway are displayed. Some improvements of rendering railway=tram will be used after next update of map style on OSM servers. But there also problems with rendering railway=rail - both major and minor (marked by service=spur/siding/yard) rails are rendered really close. At lower zoom levels rendering of railway=rail is really close to rendering of minor roads.

I am experimenting with changes to rendering of railways. Some changes are ready to presentation and effects are visible on presented examples.

Accepted changes

I am trying to find as many improvements as possible that may be proposed, discussed, improved and accepted as an isolated change. It makes discussion easier and bugs are less likely.

Turning circles on highway=track are no longer too big, code was improved. In addition highway=proposed is no longer rendered (for discussion and reasoning behind decision see https://github.com/gravitystorm/openstreetmap-carto/issues/1654).

Currently proposed changes

There are also active pull requests, some of mine are done as part of road redesign. For example there in pull request proposing better display of minor tram tracks It is open question whatever railway=tram with service=spur/siding/yard should be rendered on z14 and z15 - feedback is welcomed (more locations with rendered before/after are listed on github).

Examples of current work

Stopping too early rendering of highway=residential allows to achieve improvements like demonstrated in the first picture demonstrating changed rendering in London. But ceasing to render highway=residential on zoom levels 12 makes noise created by small buildings noticeable. These buildings are too small to be rendered in useful way but big enough to create noticeable changes.

The simplest solution would be to start rendering buildings from z13, one zoom levels later. But some of largest buildings may be usefully rendered on z12. Also, as usually there are additional complications (for example - moving only rendering of buildings to higher zoom level is not enough - it is necessary to move also rendering of amenity=place_of_worship).

On the left - current style. On the right - new style, including removal of highway=residential on this zoom level

And three examples of buildings may be handled:

stop rendering of all buildings (even the largest ones)

stop rendering of small buildings (threshold is arbitrary what is quite noticeable. In many places it is clear that some buildings are rendered and some not despite nearly the same size)

render only big buildings on z12 (my favourite - but it still arbitrary threshold and some big ones will not be rendered. But as rendered buildings are quite rare it is not so noticeable)

Jaskinia Mylna

Posted by JakubMap on 22 July 2015 in Polish (Polski)

16 lipca 20015 roku zrobiłem jednodniowy wypad do Doliny Kościeliskiej, aby dokładnie zlokalizować wejścia do jaskiń (Mylna, Obłazkowa, Raptawicka). Okazuje się, że nie jest to takie proste, gdyż na mapach wojskowych 1:10000 jaskinie zaznaczone są tylko dla ogólnej informacji. Z satelitarnych zdjęć w takiej jakości jakie mamy można tylko domyślać się, gdzie jest lokalizacja. W terenie, żaden turysta nie wiedział jaką jaskinię eksploruje. Będąc w Obłazkowej turyści myśleli, że są w Mylnej, która znajduje się 10 metrów dalej za skałą, która ją zasłania.

Ich bekomme immer nur die Standard Karte nach dem Dowload. Auch die Farben sehen komplett anders aus als gewünscht. Auch diese schlechten weißen Schriftschattierungen in einem EPS oder in eine SVG-Datei sind sehr schwer zu entfernen.

Wie geht das bitte oder liegen hier nach soviel Erfahrung technische Mängel / Fehler vor, oder macht Ihr das mit Absicht?

Österreich: Probleme beim Vergleich Gemeindenamen gegen offizielle Liste

Posted by okilimu on 21 July 2015 in German (Deutsch)

Auf der talk-at Mailingliste wurde gestern darüber informiert, das es jetzt für Österreich landesweit eine Hausnummerliste gibt [1].

Letztes Jahr habe ich eine Gemeindedatei von Statistik Austria importiert und heute in der offiziellen Liste alle "St." Abkürzungen in "Sankt" umgewandelt, wenn die Abkürzung eindeutig für Sankt stand.

Hinweis: die ausgeschriebene Schreibweise habe ich gewählt, weil bei den ersten Unterschieden in den Gemeindenamen immer in OSM die ausgeschriebene Form vorkam.

Leider war ich nicht in der Lage, hier im OSM Blog eine tabellarische Darstellung zu erstellen, daher musste ich leider die Tabelle auf meinem regio-osm.de Server ablegen [2].

In den nächsten 1 bis 2 Tagen werde ich versuchen, die Hausnummerauswertung für Österreich laufen zu lassen.

Wenn in den nächsten Tagen die Fehler bzw. Unterschiede beseitigt werden könnten, gibt es danach vorauss. eine lückenlose Auswertung.

Wenn die offizielle Schreibweise nicht korrekt sein sollte, dann im o.g. talk-at Beitrag angeben, in welchen Fällen die OSM-Schreibweise die richtige ist oder alternativ einen Kommentar zu diesem Blog hinterlassen.

Mapping Party in Tagbilaran, Bohol

Posted by maning on 21 July 2015 in English (English)

Once again, we had another mapping event. This time, in Tagbilaran City, Bohol. This is part of the series of crowdmapping events co-organized by The Asia Foundation and its local partners. The first was in Iloilo City last May 2015.

Tagbilaran mappers

During the event, Bohol Governor Edgardo Chatto welcomed all the mappers and expressed his support to implement this initiative for the whole province of Bohol.

Bohol's major income is tourism. However, when the 7.2 earthquake hit the island in 2013, the tourism industry was heavily affected. On the other hand, judging by the number of tourists (local and foreign) who was with me during the flight, I think tourism is now recovering. What a better way to help by providing a good map not only for the tourists but also for the local community!

The local partner of The Asia Foundation is the local chamber of commerce. Naturally, we focused on collecting business and tourism related map data during the field exercise.

mappers

Using phones powered by OSMAnd, we collected and updated pois: 451, lines: 94, polygons: 168.

edits

I joined one of the field teams and also took the opportunity to kickstart crowdsourcing streetviews using Mapillary.

edits

Other than several hiccups with the internet, the organizers did a very good job in managing the event. I hope the map data we collected will help in expanding the mapping community and help the province in revitalizing its tourism industry.

KF-huset i Klöse utanför Nordmaling

Posted by Nidron on 18 July 2015 in Swedish (Svenska)

Försökte hitta åt ett hus utanför Nordmaling som några 22-åriga entusiaster skaffat och gjort om till ett kulturhus. Var där i helgen på en festival, jag gillar decentraliserad kultur och tänkte det kunde vara värt att åka dit och bidra med något jag gjort trots att man inte fick nån reseersättning, ingen mat och fick heller inte använda köket, utedass mm. Det första jag gjorde när jag kom dit var att sätta mig på en säng i huset och börja gråta och sa att att det är ovärdigt att inte få ett skit tillbaks för att man försöker bidra med kultur. Han som anordnade festivalen vart sur och sa att han vart tydlig innan med vad som gällde och sa att han kunde skjutsa mig till tågstationen så jag kunde åka hem igen. Men då ville jag inte åka tillbaks till stan eftersom allt där var misär. Fick i varje fall en starköl 10,5% och en kopp kaffe och jag accepterade läget.

Dom hade café där man var tvungen att köpa all mat och jag hade inga kontanter. Hade heller inte swish eftersom jag köpt en ny telefon av billigaste sort och fick inget att funka. Alla där tyckte såklart att lösningen är att köpa en iphone istället. Försökte förklara att det var svårt att bland annat använda openstreetmap i en sån telefon men jag kände inte riktigt att jag nådde fram. Hursomhelst är jag skyldig KF-huset 40 spänn för att jag inte kunde betala maten, tänker inte betala tillbaks det.

Träffade några poeter i 20-årsåldern. De skulle göra en tre timmar lång performance då de improviserade en dikt, samtidigt som en person satt vid en dator och skrev ner allt dom sa. Datorn skulle vara kopplad till en projektor så publiken kunde se hur dikten växte fram i realtid. Poeterna skjutsade hem mig till Umeå sen.

About problems with [surface=unpaved; access=destination] roads

Posted by Mateusz Konieczny on 18 July 2015 in English (English)

Render paved/unpaved

Rendering surface value should reduce prevalence of using highway=track for any unpaved road. Unfortunately currently this tagging for renderer is really popular.

ops

There are various styles typically used to depict important low quality roads:

  • (1) lack of fill, only casing is displayed. But it works well on maps where most roads are OK, and only some are of low quality (typical for maps of Australia with unpaved roads across the outback). In areas where all or nearly all roads are unpaved results would be weird - roads render as thin double lines. Also, there would be problems with OSM data model, as rendering of crossings and places where way is split would be poor

  • (2) lack of casing or dashed casing - this style is currently used for tunnels. It would make necessary to find a new style for tunnels what is not easier. Also, people would be highly confused by using of tunnel style with a new meaning.

  • (3) dashed fill (normal road colour & special colour) - it is style that seems the most promising and examples below show how it may work. Roads under contruction are currently using this style - it is also necessary to change it.

  • (4) new separate colours of fill/casing - changing only casing is not really noticeable and/or is ugly, changing colour of fill doubles number of road classes that should be distinguishable. What worse, unpaved and paved of the same class should be similar what is quite hard to achieve. This differentiation is used really rarely, with Humanitarian style as the most prominent example.

  • (5) display in style similar to current highway=track - this style is not working well for important roads of a low quality (there are situations where [highway=primary; surface=unpaved] is used)

  • (6) dashed casing & fill (normal road style & empty space) - this style works better for roads under construction. highway=construction may start using such style

Styling of unpaved roads should:

  • introduce easily noticeable difference between paved and unpaved roads
  • do not introduce highly busy styling
  • make clear that unpaved road is worse than paved road
  • do not make unpaved road more noticeable than paved one
  • keep unpaved and paved road of the same class similar

on the left - current rendering, on the right possible new rendering

Imgur Imgur Imgur

But situation is further complicated by fact that some roads are unpaved with set access=no/private/destination. Ideally it would be clear whatever given private road is also paved/unpaved. Unfortunately this part is not really successful.

unf

On map above it is not immediately clear which road, if any is unpaved.

But in case of private roads it is more important that there is no access than surface value and unpaved roads with access=destination are quite rare so maybe this problem is outweighed by rendering surface value.

One thing that remains to be adjusted is how prominent dashes should be. Below are sets of images with various intensity of dashes. For each location there are four images

left: current rendering right: light dashes

left: light dashes right: moderate dashes

left: moderate dashes right: strong dashes

left: strong dashes right: really strong dashes

Differentiating highway=trunk and highway=motorway

I am working on two version of differentiating of these road types. First keeps all road types in in white-yellow-red gradient, with an additional road class. Second is based on the German map style. Unfortunately, after days of tweaking I am still unhappy about results so I decided to avoid publishing preview.

highway=residential on z12?

flohoff proposed to keep highway=residential on z12

I love the z10 z11 residential road change. I'd like to keep them in z12 for the moment. Residentials often make one get an impression on residential areas and population density. That would get lost.

From my test (some comparison images are linked below) - rendering highway=residential on z12, less prominent than highway=unclassified improves map for locations without mapped landuse=residential. But for places where landuse=residential is mapped it is better to not render these roads.

New osm2pgsql long-term release

Posted by pnorman on 18 July 2015 in English (English)

A new long-term version of osm2pgsql has been released, 0.88.0. This includes the work done in the 0.87.x development series and the porting to C++.

Like all versions, 0.88.0 can be obtained from https://github.com/openstreetmap/osm2pgsql

Potentially breaking changes

Major new features

One potential use for this feature is matching an existing schema for data, to allow OSM data to be a drop-in replacement.

  • In-memory pending tracking instead of in-database, with significant performance gains.

  • Rendering tables are ordered by GeoHash when created, resulting in significant performance improvements.

  • z_logic has been improved, taking into account more recent work across multiple styles. https://github.com/openstreetmap/osm2pgsql/pull/374 has more information.

Other changes

  • The node storage has been improved, and out of order nodes and nodes at 0,0 should now always be handled correctly

  • A new test suite with unit tests

  • Many bug-fixes and cleanups

Known issues

  • Append mode is not supported with non-slim. This is suported in 0.89.0-dev, but is frequently a user error. Typically, when a user does this they should instead merge input files with osmosis/osmconvert and use --create

What's next?

osm2pgsql is switching to libosmium for parsing and will require a C++11 compiler. These changes are already in 0.89.0-dev. Beyond this, it depends on contributor time and interest and if anyone decides to pay for development.

Feasibility of using satellite night-light data for identifying potential rural settlements

Posted by geotheory on 17 July 2015 in English (English)

[DRAFT - IN PROGRESS]

This reports the findings of a brief feasibility into the use of satellite night-time imagery data to aid the identification of rural settlements for humanitarian mapping purposes. The data in question is from the US Government's Earth Observation Group. I thought two products looked potentially useful: listed as Visible Infrared Imaging Radiometer Suite (VIIRS) and Defense Meteorological Satellite Program (DMSP). DMSP-OLS is a composite of visual imagery that's been filtered for e.g. cloud cover and moonlight interference (see metadata). VIIRS searches a specific spectral band to identify night-time fires, and comes both as a composite raster surface and a daily list of discrete points of identified fires.

To evaluate these I compare them to the OSM buildings layer of Unity State in South Sudan*, which was recently augmented quite thoroughly by a Missing Maps mapathon. The various EOG datasets come in tiff, png and kml formats, and have been visualised using R. The code for importing, reformatting and plotting the data is posted at Github. Results follow:

First a code demo - plotting the crop of London from the same data:

South Kivu RGC pre-existing map - has anyone seen this yet?

Posted by Jose Cisneros on 17 July 2015 in English (English)

Looking into what geographic data already exists, I came across this South Kivu map by RGC. It is six years old (mise en carte 2009) and offers an overall perspective of the southern region.

RGC (Referentiel Geographique Commun) was created to "avoid dispersion of data, redundancy of actions and incompatibility of sources". It is administered by two DRC national institutions and many are the members/producers of data (Cluster Logistic, MONUSCO, UNMACC, OSFAC, UNOCHA, UNOPS, ISCO, etc).

The positive side is that the sources are many so perhaps this map could be used as a starting point for mapping the region with more accuracy. The negative side - and major problem - seems to be a lack of validation on the field, which affects its quality.

Has anybody used/seen this map before?
