Introduction
v26 v27 27 27 JOSM is an offline editor which means everything you do won't be visible for anyone else until uploading it to the server. This makes it possible to experiment and repeatedly moving, tagging, adding and deleting elements without breaking anything. Subsequential actions on a single element will go into the database as a single modification when uploaded. 28 28 29 The first step of actual editing is to add a node to the OSM data where there will be a junction or a significant change in direction. To add a node, highlight the node button, either by clicking the 2nd button in the left menu bar, or by hitting the "A" key on the keyboard (the 2nd button should then be highlighted). Move the mouse cursor over your GPS track, and left click it wherever you want a node to be. A white dot (a selected node) should appear and a rubberline span from that dot to the mouse cursor. As you create subsequent nodes the earlier nodes will be shown as yellow dots. 29 '''Adding a Node or a Way''' 30 31 The first step of actual editing is to add a node to the OSM data. Y can add standalone nodes or you can add nodes to ways, especially where there is a junction between two ways or a significant change in direction of the way. To add a node, highlight the "Node" button, either by clicking the 2nd button in the left menu bar, or by hitting the "A" key on the keyboard (the 2nd button should then be highlighted). Then, move the mouse cursor over where you want the node, over a way or over your GPS track (if you uploaded one) and left click wherever you want a node. A white dot (a selected node) should appear and a rubber-line span from that dot to the mouse cursor. If you create subsequent nodes, the earlier nodes will be shown as yellow dots. 30 32 31 33 A series of joined nodes forms a way. 32 34 33 Ways on their own are not of much use unless they are tagged to say what they represent. [http://wiki.openstreetmap.org/index.php/Map_features Map Features] shows all the current key value pairs which could be used on a way. Ensure the properties pane is open on the right hand side of JOSM, the 8th button on the left (an icon with a wrench over a document) should be highlighted. If not click that button or hit "Alt+Shift+P". The properties pane has three buttons: a plus sign with "Add" next to it, then "Edit", then "Delete". 35 '''Adding Tags''' 36 37 Ways or nodes on their own are not of much use unless they are tagged to say what they represent. [http://wiki.openstreetmap.org/index.php/Map_features Map Features] shows all the current key value pairs which could be used on a way. Ensure the properties pane is open on the right hand side of JOSM, the 8th button on the left (an icon with a wrench over a document) should be highlighted. If not click that button or hit "Alt+Shift+P". The properties pane has three buttons: a plus sign with "Add" next to it, then "Edit", then "Delete". 34 38 35 39 Editing properties refers to all the currently selected, i.e. highlighted, elements (nodes and ways). To select anything you must be in select mode which can be switched into by clicking the first of the left hand icons or hitting the "S" key. Ensure your new way is highlighted, then click the "Add" button, a dialog box will appear and you will be asked to select a key and a value. Type in the key/value pair which represents the way you are creating, e.g. for the key type "highway" without the quotes, and for value type "secondary" again without the quotes. Now click OK. You have now tagged your way.
