Manually select OSM features for export

JOSM has a plugin called way downloader. it says that it's typical use is to follow the route of a road which is made up of a number of ways by downloading each way in turn without having to download all the surrounding data.

This is a way how you can easily download every kind of OpenStreetMap object - some steps, but quite simple.

1. Zoom in to OpenStreetMap. You must zoom in enought to be able to use the object selection tool (step 2)
2. Choose the object selection tool (on the right, see screenshot)
3. Click on the object you want to download: the orange circle that appears when you click (screenshot) shows the area covered from which all objects will be selected

4. On the left, see the results: every OSM-object inside the orange circle is listed: Choose the object you are interested in, click it

5. See the Tags for the object, in some cases it's name or other attributes

6. Got to https://overpass-turbo.eu/
7. Zoom to the area you are interested in
8. Click Wizard and insert the tag you found before, in this case: highway=footway and run the query

9. In blue, you now see the selected objects (all that have the tag you were looking for)
10. Click export and select a data type. All selected objects (the blue ones) will be included in your download.

Data format: If you want to use it in Google Earth, chosse KML, for use as GPS-navigation, choose GPX and import it to your app; for use in the web, in QGIS or other GIS software, use GeoJSON
