v64 v65 4 4 = Introduction to JOSM = 5 5 == Terminology == 6 [[Image(source:trunk/images/data/node.png,middle,inline)]] Node:: A node is a point. 6 [[Image(source:trunk/images/data/node.png,middle,inline,link=)]] Node:: A node is a point. 7 7 8 [[Image(source:trunk/images/data/way.png,middle,inline)]] Way:: A way is a line connecting multiple nodes. Way, therefore, is a general term for series of joined nodes, not just for roads or ways in reality. 8 [[Image(source:trunk/images/data/way.png,middle,inline,link=)]] Way:: A way is a line connecting multiple nodes. Way, therefore, is a general term for series of joined nodes, not just for roads or ways in reality. 9 9 10 [[Image(source:trunk/images/data/closedway.png,middle,inline)]] Relation:: A relation is an ordered sequence of ways and nodes, a logical container used to group elements. 10 [[Image(source:trunk/images/data/closedway.png,middle,inline,link=)]] Relation:: A relation is an ordered sequence of ways and nodes, a logical container used to group elements. 11 11 12 [[Image(source:trunk/images/data/relation.png,middle,inline)]] Area:: An area is a way whose ends are connected. 12 [[Image(source:trunk/images/data/relation.png,middle,inline,link=)]] Area:: An area is a way whose ends are connected. 13 13 14 14 Tag:: Tags describe what each node or way represents. Tags are organized into "keys" and "values." Keys are basically larger categories, such as "Highway" or "Land Use," while values are specific features, such as "Primary Road" or "Residential Street," and "Residential" or "Retail" land use. … … 28 28 If you have a GPX file (downloaded from your GPS receiver) for the area of interest, load it into JOSM using (File/Open). JOSM will display the area of the GPX file. 29 29 30 Next, add data for that area from openstreetmap.org. Open the download dialog by clicking on the green down arrow in the top tool bar or through the file menu. To select the area to download, first click on the "Slippy Map" tab at the top of the screen. A map of the world appears. To move around the map and select the specific area you want to download, there are several tools: Click with the right mouse button to drag the map, use the scroll wheel to zoom in and out, and click with the left mouse button to define an area. Then, click on the green down arrow [[Image(source:trunk/images/download.png,20,middle)]] to fetch the data from openstreetmap.org. 30 Next, add data for that area from openstreetmap.org.

In order to start this process you will need to know the latitude and longitude coordinates of the relevant area. The easiest way to do this is to use the download dialogues slippy map in the first tab. [wiki:Help/Action/Download Read more on the download dialogue]. … … 39 39 The first step of actual editing is to add a node or way to the OSM data. You 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. 40 40 41 To add a node, highlight the "Node" button, either by clicking the 2nd button in the left menu bar [[Image(source:trunk/images/mapmode/node/autonode.png,20,middle)]] 41 To add a node, highlight the "Node" button, either by clicking the 2nd button in the left menu bar [[Image(source:trunk/images/mapmode/node/autonode.png,20,middle,link=)]] 42 42 , 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. 43 43 … … 47 47 Ways or nodes on their own are not of much use unless they are ''tagged'' to say what they represent. The Map Features web page [osmwiki:Map_Features Map Features] shows and explains the most used tags that could be used on a point or way. 48 48 49 The first step in adding tags is to be sure the [wiki:Help/Dialog/TagsMembership Tags/Membership Dialog] is open on the right hand side of JOSM. The [[Image(source:trunk/images/dialogs/propertiesdialog.svg,20,middle)]] button on the left should be highlighted. If it is not highlighted, click on it or hit `Alt+Shift+P`. You will see the Tags/Membership Dialog, which has three buttons: [[Image(source:trunk/images/dialogs/add.png,20,middle)]] '''Add''', [[Image(source:trunk/images/dialogs/edit.png,20,middle)]]'''Edit''' and [[Image(source:trunk/images/dialogs/delete.png,20,middle)]]'''Delete'''. 49 The first step in adding tags is to be sure the [wiki:Help/Dialog/TagsMembership Tags/Membership Dialog] is open on the right hand side of JOSM. The [[Image(source:trunk/images/dialogs/propertiesdialog.svg,20,middle,link=)]] button on the left should be highlighted. If it is not highlighted, click on it or hit `Alt+Shift+P`.

Enter [wiki:Help/Action/Select Select mode] by clicking on [[Image(source:trunk/images/mapmode/move/move.png,20,middle)]] of the left-hand icons or hitting the {{{S}}} key. 53 1. Highlight the way or point you wish to select. Click the [[Image(source:trunk/images/dialogs/add.png,20,middle)]]'''Add''' button. 52 1. Enter [wiki:Help/Action/Select Select mode] by clicking on [[Image(source:trunk/images/mapmode/move/move.png,20,middle,link=)]] of the left-hand icons or hitting the {{{S}}} key. 53 1.

A [wiki:Help/Dialog/AddValue dialog box] will appear, and you will be asked to select a key and a value for each tag. Type in the key/value pair that represents the tag you are creating. For example, for the key, you might type "highway," and for the value "secondary" (no quotes). 55 55 1. Click OK. You have now tagged your way. You can add several tags to one object. … … 59 59 60 60 == Uploading to OSM == 61 If you are happy with all that you have done then you must upload your work to the OSM server. Click on the green up arrow [[Image(source:trunk/images/upload.png,20,middle)]]. 61 If you are happy with all that you have done then you must upload your work to the OSM server. Click on the green up arrow [[Image(source:trunk/images/upload.png,20,middle,link=)]]. 62 62 63 63 JOSM will give you an overview of the elements that it is about to upload. You will be asked to provide a short text summary and the source of your edits. This description will be saved with your data on the server and provides information, for example, for the [osmwww:history Recent Changes list].
