OpenStreetMap User's Diaries: What does free movie web sites escape their generosity?

Not long ago i seen that a lot web sites like www.ouchmovies.com that offer free movie knowledge of Hi-def. What could they even get free from offering these free of charge professional services? What is the hook that the users never know about? Besides, in today’s fixed-up, nothing is supposed to be presented totally free, proper?

OpenStreetMap User's Diaries: San Diego County Bus Stops and Bus Routes

I am in the process of trying to update and add bus stops and bus routes in San Diego County. The majority of current bus-stops are based on old data and are many are just a single located at an intersection. MTS and SANDAG have new SHP layers and update this information quarterly. I am approaching this in pieces so as to not break any functionality of the existing bus routes in OSM. However, from what I have seen, the vast majority of bus stops need to be changed and many routes are not added yet.

Data is developed from the General Transit Feed Specification (GTFS) data available from the transitland feed registry (formerly from the GTFS Data Exchange). Layer is updated quarterly and may not reflect most current route information.

OpenStreetMap User's Diaries: Streets as Areas

I recently added "area roads" to downtown Durham, NC. I made the surface of the roads visible on Openstreetmap. I was wondering if their is any specific way to map road areas. I currently map them as "area = highway" and "highway = service". Feel free to check it out!

Downtown Durham http://www.openstreetmap.org/#map=19/35.99361/-78.89968

Downtown Chapel Hill http://www.openstreetmap.org/#map=19/35.91627/-79.05645

Chapel Hill Public Library http://www.openstreetmap.org/#map=19/35.93251/-79.03549

All three links lead to a place in Openstreetmap where I mapped roads as areas.

I anyone else mapped roads as areas, please reply a link to the location!

OpenStreetMap User's Diaries: 私家訳Organized Editing Policy

本エントリーは、Organized Editing Policy (https://osm-dwg.limequery.org/741554) の私家訳です。意訳を多分に含みます。アンケート本文はnyampireさんの訳 (http://qiita.com/nyampire/items/c801b0bc562436951f9a) をどうぞ。

--ここから--

組織的編集に関するガイドライン

OSMが始まったころは、趣味の範囲で空いた時間を利用してマッピングを行う活動が主なものでした。マッパーは好きなものをマッピングし、好きなツールを使い、自分がマッピングした内容に対して自分で責任を負っていました。

OSMが拡大するにつれ、組織でマッピングする活動が増えてきました。企業がマッピングチームを雇い、特定の地域や特定の用途を想定してマッピングをおこない、OSMデータを改良しています。他にも学校の授業でOSMマッピングするような、非有償のグループ活動もあります。

このような組織的マッピング活動は、今日ではOSM活動の一部分となっており、正しく活動が進められたならば、OSMがより良いものになり、知名度も上がります。

個人マッパーと組織マッピンググループの間で、コミュニケーションを円滑に行い、どの参加メンバーも平等であることを明確にするため、OSMFデータ・ワーキンググループでは組織的マッピンググループに対するガイドラインを策定中です。ガイドラインでは組織的マッピンググループに対して一定の透明性確保を要請する予定です。例えば、チームメンバーのアカウントを開示することなどが挙げられますが、すでに多くのグループが自主的におこなっている内容でもあります。

ガイドラインに対してOSMコミュニティが何を期待しているのかを把握するため、アンケートを準備しました。このアンケートは、OSMを編集している人、これから編集しようと思っている人、個人マッパー、マッピンググループの一員などすべての人を対象にしています。アンケートの結果をもとに、ガイドラインをより良いものにしていきます。

本アンケートおよび策定されるガイドラインにおいては、paid mapping(有償マッピング)を、「他の人または団体から、何をマッピングするのか指示され、その報酬として金銭を受領したOSM編集」と定義します。また、other organised mapping(その他組織的マッピング)を、「他の人または団体から、何をマッピングするのか指示されるが、金銭を受領しないOSM編集」と定義します。

アンケートは12問あります。

OpenStreetMap Blog: Recap of Google Summer of Code 2017

With this year’s Google Summer of Code’s recent successful completion, we thought it would be a good idea to recap and shine a spotlight on the individual projects. It’s the 10th year we were participating with success, so thanks to Google for supporting us again, and thanks to the Engineering Working Group for managing our participation this year!

The Google Summer of Code is a program run by Google to match student developers to open source projects. Students may apply to any of the participating projects, based on their preferences or relevant experience. The students that get selected receive a stipend (paid by Google) to spend one summer working on their project, gaining valuable experience while contributing code to real-world projects.

This year, we had five student projects with a really great student developer for each of them and all of them passed, i.e. they all finished their project plan in time. Additionally, there were two OSM-related projects outside of the OSMF umbrella: Indoor Support for Marble based on OSM and a plugin API to display OSM data on NASA Web WorldWind. But we had a bit of bad luck as well: Google gave us the opportunity to select even more students and, while we had applications from two more great students lined up, they didn’t start their project with us due to reasons not within our control.

Anyway, as not everyone was following the students’ work, we thought we should share the outcome of this year’s summer of code with you.

OpenGL Renderer for libosmscout

Let’s start with the first project, which is part of libosmscout, a C++ library for offline map rendering, routing and location lookup. What libosmscout doesn’t have right now is a render path based on OpenGL.

Tim Teulings, the mentor for this project, shared with us that he was very happy to see Fanny work on that task as none of the existing project members had time or the respective know-how, but it was still a highly requested feature. So they felt very lucky to have a great student like Fanny to work on it. What’s more, she even said that she’s keen on continuing to work with that project.

Her part of the library with a small demo application can be viewed on Github and all of her work was continuously merged.

© OpenStreetMap contributors

As you can see, her renderer works quite well and produces beautiful maps. The objective was to support areas, ways, labels and ground to be rendered correctly. In addition to that, the code now supports most of the styling options and works on Linux, as well as on Windows. You can read more about the work and the results on her user diary.

We hope Fanny will stick to her plan to continue to work on libosmscout and stay a part of our great OSM community!

3D Model Repository

The next project we’d like to present to you is the 3D model repository by Pedro (also known as n42k). The project idea has been around for a while, but in the past we either didn’t have a good student or failed to get enough project slots. This year was different and we finally got both!

Eiffel Tower Model by joe89v (source)

The task itself is easy to explain: “We want a website that allows uploading 3D models to use for OSM”. But still, there were a lot of decisions to make: The site is now intended for all kinds of models, unlike previous efforts targeted only at buildings. It will initially focus on OBJ as a file format, and will provide unique IDs that can be easily linked in OSM. To make sure that the models fit the needs of the various applications in the OSM ecosystem, developers from two 3D renderers (OSM2World and OSMBuildings) mentored the project together.

Pedro published some of his work in his diary and his highly appreciated code can be viewed at Gitlab. Currently, the mentors are in the process of checking with the OSMF’s Licensing Working Group and others to deal with some details like hosting, branding and some “legal issues” (e.g. with regard to the geocoding guideline), but we’re expecting to see the site go live later this year.

Enhancing JOSM pt_assistant

Another project we want to talk about is the enhancement of the PT Assistant Plugin for JOSM by Giacomo Servadei. While the plugin name suggests this is all about public transport, the scope of this project grew to include hiking and bicycle routes as well.

Besides the extension of scope, Giacomo worked hard to extend the plugin and make it even more useful. For example, it now allows you to sort stops according to the sequence of the ways in the route relations, and it helps you with splitting roundabouts while keeping the route relations that pass over it. But it also has a better check for problems and now reports and suggests fixes, for example gaps of a single way or routes that don’t start or end neatly on a stop_position node near to a corresponding platform node.

You can read about Giacomo’s main results and his detailed timeline in the wiki. It also includes direct links to the dedicated tickets and associated patches. All of his work got merged and you can easly activate his plugin and test the outcome for yourself.

In addition to that, Polyglot, who was Giacomo’s mentor for this project, has written some diary posts about it.

Web-based Public Transport Editor

Dkocich worked on a similar project, but this time it wasn’t about a JOSM plugin. Instead, the goal was to create a website to edit public transport relations without the need to start a full blown editor.

While the editor is not merged yet, this will probably happen soon. Before the finished version of the editor is published by his main mentor Ilya, you can already have a look at his great work and test his version of the OSM Public Transport Editor. You can also have a look at his code on his Github project.

JOSM Refactoring

The next project in this list is all about JOSM’s core code. This project was mentored by Michael Zangl, a former student who had participated in GSoC the two previous years, working on different JOSM tasks – an experience that had allowed him to gain a very deep understanding of JOSM’s core. This year’s project started out as an effort to refactor the menu bar to have a proper API to use, but the project’s goals got extended and modified a bit during the summer.

Bogdans worked hard to dive into JOSM’s codebase and familiarize himself with JOSM. You can have a look at his work on his wiki user page, which also contains a list of tickets he worked on and patches he wrote which got merged.

Much of his work is “under the hood”, so unless you’re contributing to JOSM development or plugins yourself, you probably won’t easily notice most of the improvements while working with JOSM. Still, there are some visible updates: Bogdans added the option to search based on presets, and also merged the “Download” and “Download from Overpass API” actions into a single dialog box. Furthermore, there’s a Wizard that helps mappers with constructing Overpass queries now, much like the one known from Overpass turbo.

Again, you can read more about his work on Polyglot’s diary, since he served as a co-mentor.

Summary

This was a great Google Summer of Code again and we’re very happy that we were able to participate. We want to use the opportunity to thank all the students for their work and we’re hopeful that you as a user will benefit from one of them as well. In addition to that, we’d also like to thank the mentors for spending their spare time to help the students finish their tasks and the EWG for doing the administration of this year’s GSoC.

After the conclusion of this year’s GSoC, we performed a small survey among our mentors to gather feedback, and even though some of them had to invest considerable hours in it, they unanimously responded that it was worth their time and that OSM should participate again next year. So we conclude by tasking the EWG to apply again next year!

OpenStreetMap User's Diaries: A cow made of corn

It’s corn maze season in North America: for a couple months, farms all over are inviting folks to explore mazes they’ve cut out of corn fields.

CVNP A corn maze in Northeast Ohio by David Fulmer, CC BY 2.0.

In OpenStreetMap, several corn mazes have been micromapped across Southwest Ohio. The designs change each fall, so the mazes have to be micromapped all over again.

Wendel Farms pumpkinsLook sideways: these pumpkins at Wendel Farms were previously visible in Bing and other aerial imagery, but the ways clearly need to be deleted now that the pumpkin design has been cut down (and replaced).

None of the aerial imagery providers have this fall’s maze designs yet – after all, these doodles are only weeks old in some cases. So I turned to the farms’ websites and Facebook pages, where farmers have posted aerial photos of their own mazes. I wrote to them, briefly describing OpenStreetMap and asking permission to update the map based on their photos. A few got back to me, happily giving permission. It’s free publicity for them, after all.

Wendel Farms cow This year, Wendel Farms’s corn maze depicts a cow surrounded by various dairy products.

Since my preferred editor, iD, currently lacks support for overlaying arbitrary images, I built a copy locally and modified it to display the photo above the normal imagery and below the data. Using my browser’s Web inspector, I added a pattern to the SVG document’s <defs> element:

<pattern patternUnits="userSpaceOnUse" id="maze" width="956" height="1174">
    <image x="0" width="956" height="1174" href="dist/img/pattern/maze.jpg" y="200" />
</pattern>

and overrode the CSS style of the <path> element representing the edges of the field:

.area-fill > .w107158117 {
    fill: url("#maze") !important;
}

I probably could’ve done something more sophisticated to keep the image anchored while panning and zooming, but this was good enough for a quick, informal micromapping project.

Wendel Farms cow

Not too long from now, these corn mazes will’ve been cut down and plowed under, and the paths will also be deleted from OpenStreetMap in anticipation of next year’s corn maze season. But a snapshot of this fall’s designs will eventually appear in the standard aerial imagery and remain there for years to come. As a result, mappers can compare a corn maze’s appearance and the date on which the maze was micromapped to determine the vintage of the surrounding area’s imagery.

In the meantime, if you poke around Southwest Ohio, be on the lookout for cows and other scenes hidden among the cornstalks.

OpenStreetMap User's Diaries: Survey on organised editing

The Data Working Group is conducting a survey as part of its work on a policy covering paid mapping.

When OpenStreetMap started, it was largely a project of hobbyists contributing to OSM in their spare time. They chose freely what to map and which tools to use, and they took individual responsibility for their contributions.

The continuing growth and popularity of OSM have also brought more and more organised mapping efforts, mostly in the form of companies setting up paid data teams to improve OSM data in specific regions or for specific use cases, but also unpaid groups like school classes that are directed to work on OSM.

These organised mapping efforts are an integral part of today's OSM contribution landscape and, when done well, help make OSM better and more widely known.

In order to ensure good communication, and a level playing field, between individual community members and organised editing groups, the OSMF Data Working Group has been tasked with developing guidelines for organised groups. These guidelines will above all set out some transparency requirements for organised groups - things that are already voluntarily followed by most groups today, like informing the mapping community about which accounts edit for the team.

We have prepared the following survey with a few questions about such a policy to give us a better understanding of what the mapping community expects from such a policy. The survey is aimed at everyone editing (or planning to edit) in OSM, whether as individual mappers or as part of a team, and your answers will help us in fleshing out a draft policy.

Within the scope of the survey, and the policy to be written, we define paid mapping (or paid editing) as any editing in OSM performed by someone who is told by a third party what to map (and potentially also how to map it) and who receives money in exchange. We define other organised mapping (or editing) as any editing that is also steered by a third party, but where no money is paid.

Please participate in our survey here: https://osm-dwg.limequery.org/741554

OpenStreetMap User's Diaries: Gravar tracks / trilhas usando gps automotivos

As vias dos novos loteamentos normalmente não estão visíveis nas imagens satelitais disponíveis no OSM para edição, em razão da frequência de atualização das mesmas. A solução é percorrer as novas vias, gravando tracks/trilhas gpx para utilizar nas edições.

Realizei alguns testes comparativos, gravando alguns tracks utilizando um gps automotivo Garmin Nuvi 2580 e um gps de mão, o Garmin 76csx.

Para obter uma maior precisão, em ambos gps foram desativadas as funções "Lock on road". Isto é muito importante, para forçar o gps a gravar a sua real localização. Sem este procedimento, o equipamento realiza "correções" a fim de coincidir a localização com o mapa visualizado na tela, obtendo um track impreciso.

No Garmin 76csx, o procedimento consiste em: http://wiki.openstreetmap.org/wiki/Garmin/eTrex_Vista_HCx

Nos gps automotivos Garmin Nuvi, o procedimento varia um pouco conforme o equipamento, mas de forma geral:
- linha nuvi 1000 ou superior: http://www.gpsinfo.com.br/viewtopic.php?t=4581
- linha nuvi 2xx e 7xx: http://nastrilhas.com.br/site/index.php/gps/23-garmin/17-gravar-um-tracklog-no-garmin-nuvi-2xx-e-7xx
- nuvi: http://www.mundooutdoor.com.br/melhorando-tracklog/

Após a gravação, foi realizado o efeito comparativo e concluíu-se que a diferença entre os tracks gravados pelos equipamentos é praticamente desprezível:

  • Exemplo 01:

  • Exemplo 02:

  • Exemplo 03:

Assim, os colaboradores do OSM que quiserem utilizar seus gps automotivos para obter tracks para edição, podem fazê-lo sem maiores problemas. Ou podem ser adquiridos equipamentos usados a preços reduzidos, viabilizando os mapeamentos.

Quem tiver interesse, mesclei os tracks do gps Garmin 2580 com o Garmin 76 e subi para as trilhas do OSM:

OpenStreetMap User's Diaries: Kathmandu beckons

Quite excited to be at the SOTM Asia 2017 Conference in Kathamandu this weekend. This year I'll be talking about my OpenStreetMap readiness assessment work and walk through on how the approach varies from prior art, opening new avenues for mappers to explore data coverage.

I'm also collaborating with Jennings Anderson on his contributor metrics analysis & trying to understand how does mapping community health reflects on the readiness work.

If you're at Kathmandu this weekend, do catch me up for more conversation over a Chiya! 👋

OpenStreetMap User's Diaries: Milestone

Depois de alguns meses de dedicação e aproximadamente 23 mil buildings adicionadas, atingi a meta de desenhar casas e demais edificações em todas as vias da área urbana de São Gabriel (RS). Ao todo, 37 bairros e 3 núcleos urbanos autônomos. Faltam casas que estão encobertas ou que ainda não aparecem nas imagens aéreas, as quais serão adicionadas quando eu ou outros mapeadores formos coletar dados a campo (o que eu considero a melhor parte do mapeamento). A tarefa por muitas vezes parecia interminável mas vendo o resultado final valeu o esforço. O trabalho agora é de melhorar o mapeamento na zona rural de São Gabriel em paralelo com outras tarefas na região central e campanha do Rio Grande do Sul. Espero que com a geometria disponível, usuários sejam incentivados a adicionar informações, como numeração e nomes de estabelecimentos, relativas a cada building.
