The data is live on OpenStreetMap immediately. This is important as it will show other users who see your changesets what this changeset was intended to modify and from where you took the information. Before you upload, add a proper changeset comment and specify what source you used. If there are any errors or warnings, do your best to fix them. Review all validation warnings and resolve all errors before you upload. This will automatically trigger validation. To upload the data, click on the green up-arrow button on the left in the menu bar. This will copy only tags - not the geometry. Then select the other object and paste with ctrl + shift + v. Just select one object, copying with ctr + c. You can copy and paste tags from one object to another. Try adding a preset and then review the modifications in the tagging panel. They can be found in the “Presets” menu where they are organized into logical categories. Presets are common tags or tagging combinations that can be applied to objects. Simply hold shift to select multiple objects. The example below tags two ways at the same time. If for some reason this panel is not visible, you can enabled it under the “Windows” menu. You can add, modify or delete tags directly in the tagging panel in JOSM’s side bar. To prevent ways from connecting when drawing, say when drawing a road close to buildings, hold the ctrl key, while clicking the mouse. This is useful to create logical connections, for instance between roads of different type. In JOSM speak, you can glue, unglue, split and combine them. If you ever make a mistake, ctrl+Z, or command+Z on mac, will undo the last change. To delete data, use the del key of your keyboard or on a mac, use fn+delete. Then release the mouse button where you’d like to drop them. To move nodes or ways click on them, hold the mouse button pressed and drag them. To draw a closed way, finish a way with a click on the first node you drew.Ĭlick the “Select” button to select existing nodes or ways. For drawing single nodes, simply double click on the map. Subsequent clicks on the map will set nodes connected by a way. Creating dataĬlick the “Draw nodes” button to enter the data creation mode. If you observe an offset in the imagery, you can correct for it by selecting the “New offset” item in the “Imagery” menu.

To download GPS tracks from OpenStreetMap, check the “Raw GPS” box in the download dialog. For reference, check existing features on the map and compare them with the imagery or download GPS tracks. That is, due to complexities in processing satellite imagery, features on imagery may not be at the same location as they are in the real world.
When using imagery, keep in mind that imagery may be offset. Simply select one of them from the imagery menu and you’re ready to go. Bing and Mapbox may have different levels of detail and clarity in different places, so often worth checking both. JOSM comes with a variety of pre-configured satellite imagery layers - the Bing and Mapbox layers being the most popular ones. You will routinely use imagery for mapping. To start editing, download an area from OpenStreetMap by using the green down-arrow button on the left in the menu bar. Note that this section only focuses on the mechanics of editing with JOSM. Another popular editor is iD, commonly used for short and simple, browser based editing sessions. This guide will get you started mapping with the Java OpenStreetMap editor (JOSM) - a powerful and popular desktop editor for OpenStreetMap.
