    3 [[Image(source:trunk/images/mapmode/improvewayaccuracy.png)]] ''Keyboard shortcut:'' **{{{W}}}**
     3[[JOSMImage(mapmode/improvewayaccuracy,link=,48,,middle,margin-right=20)]] ''Keyboard shortcut:'' **`W` ([ExpertMode expert mode] only)**  — is one of the [wikitr:/Help/Menu/Mode#Workingmode working modes]
    44
    5 This mode is useful when you are improving accuracy of the ways that have already been mapped before. The goal of the mode is to substitute dragging and dropping nodes with clicking to quicken the editing process.
     5This mode can ''add, move and delete'' **nodes** of the previously entered [wikitr:/Help/Concepts/Object#Ways ways]. This mode is used only to update existing data (ways).

     7The goal of the mode is to substitute dragging and dropping nodes with clicking to quicken the editing process. It is the most useful with natural objects that change its shape (a riverbank, burnt forest, flooded areas and so on) and some man made obejects that lack precise boundaries (landuse areas, highways as ''OSM ways''). Consider other tools for man made objects (where accurate angles may be desired).

    99== Usage ==
    10 [[Image(JOSM-plugin-IWA-example.jpg, right)]]
     10Activate this mode and select a way. To start working on a different way without leaving the mode, unselect the current way by pressing **`Esc`** and click on another way.
    1111
    12 ''Before you begin:'' Make sure you have a high-resolution imagery or enough GPS traces below your data layer.
     12The mode automatically finds segments and nodes that are the closest to the cursor. Candidate for deletion/move/addition will be changed as many times as you move cursor.
    1313
    14 1. Select a way you want to work on.
    15 1. Click on the **Improve Way Accuracy** [[Image(source:trunk/images/mapmode/improvewayaccuracy.png)]] button on the left panel to enter a special editing mode.
    16 1. 
    17     * ''To move existing nodes:''[[BR]]
    18       Click on the map where you think a node should be. The highlighted (nearest) node will be moved there.
    19     * ''To create new nodes:''[[BR]]
    20       Press and hold **{{{Ctrl}}}** button and click on the map. A new node will split the segment that is the closest one to the cursor.
    21     * ''To delete existing nodes:''[[BR]]
    22       Press and hold **{{{Alt}}}** or **{{{AltGr}}}** button and click on the map. The highlighted (nearest) node will be deleted. **Please try to use as much existing nodes as you can, because thus you keep their history.**
    23 1. To start working on a different way without leaving the mode, unselect current way by pressing **{{{Esc}}}** and click on another one.
     14The highlighted node can be locked (see [#Locksegment Lock segment]).

    25 == Tips ==
    26 * The plugin automatically finds segments and nodes that are the closest to the cursor. However, if you want to get more flexibility, you can **lock the highlighted node/segment** when moving a mouse. Press and hold **{{{Shift}}}** or left mouse button and the focused node or segment will be kept the same no matter where you move the cursor.
    27 * JOSM has a [[WireframeToggle|wireframe view]] that turns off any styles and makes lines very thin. You can try it by pressing **{{{Ctrl+W}}}** It might be a good idea to toggle that view before improving ways accuracy as it allows to see the imagery below the data layer in a much better way.
     16When you add or move nodes, **they are not merged with existing nodes** as it happens in the [wikitr:/Help/Action/Select Select] or [wikitr:/Help/Action/Draw Draw] modes. You have to quit editing in ''Improve Way Accuracy'' mode and use [wikitr:/Help/Action/MergeNodes merge nodes] tool or alternatives.
    2817
    29 == Limitations ==
    30 * **When you add or move nodes, they do not bind to nearby objects** as it happens in the [[Select|Select]] or [[Draw|Draw]] modes. This is not needed during the way shape improvement, but in case you would like to do so, select the nodes in the ''Select'' mode and [[MergeNodes|merge]] them, e.g., by pressing **{{{M}}}**.
    31 * **You cannot delete nodes that are connected to more than one way or that have tags** to prevent accidental breaking of topology or loss of information. Note that "uninteresting" tags are excluded, like FIXME, note, source, etc.
     18=== Move existing nodes ===
     19Click in [wikitr:/Help/MapView Main view] where you think a node should be. The highlighted (nearest) node will be moved there.
     20
     21''Helper geometry: dashed red line - indicates a way after moved node''
     22
     23=== Create new nodes [[JOSMImage(cursor/modifier/addnode,middle,link=,inline)]] (+`Ctrl`) ===
     24
     25[[Image(JOSM-plugin-IWA-example.jpg,right,link=,margin-left=15)]]
     26
     27Hold **`Ctrl`** button and click - a new node will be added into highlighted segment.
     28
     29''Helper geometry: solid red line - indicates a way after new node''
     30
     31=== Remove nodes [[JOSMImage(cursor/modifier/delete,middle,link=,inline)]] (+`Alt`) ===
     32
     33Hold **`Alt`** button and click - the highlighted node will be deleted.
     34
     35Please try to keep as much existing nodes as you can, because thus you keep their history.
     36
     37**You cannot delete nodes that are connected to more than one way or that have tags** to prevent accidental breaking of topology or loss of information. Note that "uninteresting" tags are excluded, like `FIXME`, `note`, `source`, etc.
     38
     39=== Lock segment ===#Locksegment
     40* Lock moved node: [[JOSMImage(cursor/modifier/lock)]] + `Shift` - when moving a mouse, hold **`Shift`** or left mouse button and the highlighted node or segment will be kept the same no matter where you move the cursor.
     41* Lock added node: [[JOSMImage(cursor/modifier/add_node_lock)]] + `Ctrl` `Shift`

     44== See also ==
     45* [[JOSMImage(dialogs/mappaint/wireframe_small,24,link=,middle)]] `Ctrl+W` [wikitr:/Help/Action/WireframeToggle "Wireframe view"] - turns off any styles and makes lines very thin, it might be a good idea to toggle that view before improving ways accuracy
     46* [wikitr:/Shortcuts#Altkey Shortcuts Alt key] - if `Alt` doesn't work
     47* [https://github.com/JOSM/improve-way ImproveWay plugin] - extends the Improve Way Accuracy mode with helpers to place nodes at accurate distances and angles.
