GPS軌跡（GPX tracelog）是一種可以將旅途的軌跡記錄下來的檔案。你可以參考他人在開放街圖中上傳的 GPS 軌跡（大部份都是公路的路線資訊）將其繪製在開放街圖中。你也可以錄製自己的 GPS 軌跡，錄製的方法會在田野實察的章節中說明。以下為在編輯器中取得並使用 GPS 軌跡的方法：

The idea behind outdoor mapping is to go out and gather data. This is often the only way to map everything on the surface. Many shops and points of interest are often unseen with armchair techniques. Here are some outdoor techniques.
For quick editing of maps on the go, try out StreetComplete. It asks you simple questions about POIs nearby and submits your answers back to OpenStreetMap.
You can use paper to take textual notes or draw. You can also use an electronic device to take notes.
Field Papers 是一個可以線上製作可供列印的地圖的工具，你可以使用 Field Papers 將地圖印下來後在紙上做註記。
You can use a camera, a smartphone, or a voice recorder, to take photos, videos, and voice notes. This is very simple, but you'll need to manually or indirectly figure out the location the media was taken. Some techniques for this are described in Photo_mapping, Audio_mapping, and Video_mapping. You can also capture media with a location, allowing JOSM to put them at the right place on the map. See 拍攝包含位置資訊的影像.
A tracelog is a file containing a recording of the path of a trip. Smartphones and dedicated receivers can record tracelogs. For smartphones, many apps are available. Search for one with GPX file export support. It is the format used by OpenStreetMap. Once recorded, the tracelogs can be used to draw roads on the map. Once you obtain a GPX file, you usually transfer it to the computer. You can then import it to JOSM or upload it so that others can use it. Some smartphone apps can upload the recordings directly to OpenStreetMap as well. Once uploaded, you and others can download and use the GPX track and use it as described in the Armchair Mapping section about tracelogs, or you can import it to JOSM without uploading it (or prior to uploading it).
If your GPS receiver or app doesn't create GPX files, you can convert them.
Note that some devices are more accurate than others. If your device is inaccurate, consider doing more than one recording, then putting the road on the rough average path of the traces.
Ensure that your GPS unit has the 'Snap to road' or 'Lock on road' option switched OFF, if it has one.
Tracelogs can be uploaded with various privacy settings, see Visibility_of_GPS_traces.
A very popular Android app for GPX recording is GPS Logger, click here for a detailed learnOSM guide. If you also want to capture photos and audio recordings with their location on Android, see Pick_your_mapping_technique#Explicit_Waypoints.
Some devices or smartphone apps support note creation along tracelog path. The notes are embedded in the GPX file and can be seen on the map when you import the file to an editor.
Some devices (usually GPS receivers that have no keyboard) allow you to insert sequentially numbered points of interest by clicking a button. In the example shown, the cartographer stopped in a pub car park, and marked a waypoint which was stored as number 206. Use a notepad, or dictating-machine, to record what that waypoint corresponds to. Although it's sometimes possible to type this information into the GPS itself, it can be very fiddly.
Some GPS models allow you take an 'average' point. This will take multiple GPS points and then average all the points, in theory creating a more accurate waypoint. Usually this is used when accuracy is higher priority with the data collection and time isn't as much as a factor but this can still be done quickly.
Photos and voice recordings can be automatically correlated with a location using many techniques. This usually involves transferring the media files to the computer and importing them to JOSM for processing. We'll only explain the most common techniques briefly here. Please see Photo_mapping, Audio_mapping for more detailed info and specific instructions.
現在有許多的手機和相機都可以在拍攝相片時同時將地理資訊加入至相片檔案中，你只要在拍攝前開啟你的裝置內的設定，並匯入 JOSM 編輯器中，即會在正確的位置顯示圖片，在製圖時比對資料非常方便。
For photos that have no embedded geo-location data, or for any audio file, you need to synchronize the media with a GPX log. This allows JOSM to place them on the proper place on the map. There are two primary ways to do it:
Some smartphone apps can record GPX logs, and can also be used to take photos voice notes and text. They then embed the media file names and the time they were taken inside the GPX file as explicit waypoints. This ensures the media can be properly located on the map when imported to JOSM.
This technique allows you to use separate devices. (It can still be used on a single device, too) For instance, you can record tracelogs with a smartphone or a GPS receiver, and take photos with a regular camera, and the photo can still be located on the map!
Every file has a timestamp indicating its creation date. If you are recording a tracelog and you take a photo or record a voice note during that time, a capable editor like JOSM can put that media on the proper location on the map by correlating the file's time stamp with the tracelog. The neat thing here is that the device that took the media and the device recording the tracelog don't have to be the same device. Beware that some file transfer techniques modify and ruin the file's timestamp. Refer to Photo_mapping, Audio_mapping for more details.
Upload street view data
You can use Mapillary or OpenStreetCam to upload data (through Android/iPhone apps or through the web). You can then use that data as described in Pick_your_mapping_technique#Street_view_data. The advantage is that others can use your media as well.
