OpenStreetMapを応援するには

あなたの近所をマップする!
もうすでに、the mapを見ていますね？そして、あなたの街を探したでしょう。たぶん、あまり満足のいく結果でなかったか、全く見つからなかったか。いずれにせよ、地図はまだまだ未完成だったんではないですか？だからといって使えない！もう見ない！とならないで！（このページを見てくれていると言うことは、まだ見捨てられたわけではないということだと信じたいですね）。でも、その状態も今だけのこと。そう、「あなたが参加して、世界に貢献して、世界にアピールできる」チャンスなのですから。私たちは、地図を「既にある誰かの権利が設定された（日本で入手できるほとんどの地図がそうです）地図」を『全く見ないで』、私たちのための地図を「創っている」のです！街をあるき、調査し、様々なマッピング技術を駆使して創っています。でも、特殊な知識は必要ありません。プロジェクトの全地球的な側面を理解していなくても、あなたの近所でできることはたくさんあります。私たちは、この地図を向上させるために参加して、ここかしこで少しでも貢献しようという方々を応援しています。多くの手で少しづつ良くしていくことが、このプロジェクトを良くする一番の方法です。 さあ、アカウントを作成し 編集を開始しましょう!
おそらくあなたは、たいしてこのプロジェクトの地図で網羅もされていない地域（すんでいる地域によってはすべての国土の領域）にすんでいるのではないでしょうか。そうチャンスです。あなたの参加が必要です。そして、地球のなかであなたの存在を示しましょう！
あるいは、一見おおよそ出来上がっているような地域に住んでいるかもしれません。しかし、ぜひ理解いただきたいのは、我々はもっと詳細な地図情報を集めたいと思っているのです。パブ、居酒屋、レストラン、ときには郵便ポスト、バス停にいたるまで。すべては私たちのデータとして追加できます。あなたの近所の注目スポット、それを入力しちゃいましょう！もちろん、いまのデータでも、誤字脱字などで間違っていたならばその修正は大変感謝！！です。
あなたの近所、市、区でほかにどんな人が参加しているか知りたい、とおもいます。Mapping Projects ページに進み、ほかのOSMユーザのプロフィールをみてみてください。日本の方は、OSM Japanを訪れるのもいい考えです。

Getting data
Lots of raw data is needed. This means gps data produced by collecting the tracklogs from GPS Receivers. You need an OSM account to upload tracks. After logging in, use the page containing your tracks to upload new ones.
You can make your GPS tracks private or public. In the latter case, other users can use your tracks to convert them into points and streets, but be aware that this can include some privacy issues.
If you like to contribute more than "just" the tracks (which already is a huge contribution), then convert them into ways. See the Starter Tutorial for details.
Mapping existing tracks
If you don't have a GPS unit then you can help by mapping tracks that have already been uploaded. In London eCourier have donated the track logs from their couriers, which means that there is a clear track for almost every major road and quite a few minor roads right out to the M25 and beyond. If you know any part of London and don't have a GPS (or have flat batteries) then this is where to start. It really helps to do an area that you are familiar with. Follow the illustrated guide to getting started with OSM editing.
The Korea project includes some experimenting with remote collaboration, where users from anywhere in the world can create maps using data, including tracks, waypoints, photographs, and notes, collected in Korea. See Korea Mapping Guide.
You can also use imi's JOSM Java software to download the raw GPS tracks for a given area from OSM and then overlay what has been added in terms of nodes and line segments, again from the OSM server. It takes a while to do this for a larger area (say a country), but gives a pretty instant indication on what tracks have not yet been turned into streets or other linear features. You can then use JOSM to create nodes and line segments and upload these back to OSM. Don't be tempted to download for too big an area. It puts big loads on the platform, you probably won't have enough memory in your box and it takes a hell of a long time to pull the GPS trackpoints out of the server. Stick to a manageable area at first (say a city) and then collect more data from OSM as required by moving the window of view around.
Recording tracks using a GPS receiver
If you have a GPS unit that is capable of recording a track that can later be uploaded to a computer or a GPS unit that can be directly connected to a Laptop, PDA or Smartphone by Bluetooth, Serial Port or USB, then you can help by going out and recording tracks of any journeys that you make and then uploading them to the database. These tracks are useful even if you don't plan to mark up the roads yourself, there are people without GPS units who will do this if you don't. Tracklogs of roads that have already been mapped are also useful as they can help to validate the true path of a road by providing more sample points.
- Go for a walk or a cycle ride or a drive (or whenever you take any kind of journey)
- take your GPS with you
- switch your GPS on at the start of the part of the journey that you want to map
- set the GPS to tracking mode so that it records your journey. If your GPS unit has a "Snap to road" option, make sure that option is switched OFF, or you might end up merely recording a direct copy of the map loaded into the GPS unit, which is not only a copyright infringement, but is possibly going to be less accurate than the track you would otherwise record.
- if you plan to later make up the roads take some notes of the street names etc (unless you already know them - you cannot later get them from (or check them on) a map as this would infringe copyright).
- record your route along any linear feature. Rivers and waterways, footpaths, bridleways, rail and tramways, and any other fixed linear features are of interest to OSM. In future we will want points of interest and area information so add this information in your travels where you can and save it for when OSM can use this extra information. At the moment it can only effectively handle linear features.
- it may be helpful to record waypoints if there are features that would not obviously show up on a track log (for example a mini-roundabout).
- When you get home upload the tracklogs to the OpenStreetMap server.
- Finally, follow the instructions above if you want to transform your tracklogs into roads and streets.
- Repeat the process as often as you can.

Projects
The Mapping projects page lists projects which you might like to help with. These will be goal oriented activities, such as mapping a particular town or city, or the motorway network for a country. If there is a project that interests you then you will be very welcome to get involved.
Rendering
Tiles@home is a distributed computing project for rendering OSM data for use with Slippy Map, the online map browser.
Developer
A lot of software development work is taking this project in many different directions. As mentioned above, we have created various map editing tools. In fact OpenStreetMap is powered by open source software from the slippy map interface, down to the underlying data access protocol (a web service interface for reading and writing map data). There is lots of scope for sub-projects working with our data and using our data, but we also need help fixing bugs and adding features to our core components.
So where to start?
- The Develop page is the portal for developers document technical details and find areas they are interested in.
- Join the 'dev' and 'talk' mailing lists to get a feel for the most current activity.
- The Protocol specification is perhaps the main piece of decumentation to get your head around.
- The Things To Do list is mainly development tasks
