v40 v52 1 1 [[TranslatedPages]] 2 2 = Improve Way Accuracy = 3 [[ Image(source:trunk/images/mapmode/improvewayaccuracy.png,nolink,middle)]] ''Keyboard shortcut:'' **{{{W}}}** — is a one of the [wiki:Help/Modes JOSMmodes]3 [[JOSMImage(mapmode/improvewayaccuracy,link=,48,,middle,margin-right=20)]] ''Keyboard shortcut:'' **`W` ([wikitr:/Help/ExpertMode expert mode] only)** — is one of the [wikitr:/Help/Menu/Mode#Workingmode working modes] 4 4 5 This mode can ''add, move and delete'' '''nodes'''of the previously entered [Help/Concepts/Objectways]; this mode used only to update existing data (ways).5 This 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). 6 6 7 7 The 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). 8 8 9 == Activation steps == 9 == Usage == 10 Activate 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. 10 11 11 Two options: 12 * Select a way, then [Help/Modes#Activateamode activate a mode as usual] 13 * Activate a mode, then select a way to update (icon: [[Image(source:trunk/images/cursor/modifier/mode.png,middle,nolink)]]) 12 The 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. 14 13 15 T o start working on a different way without leaving the mode, unselect current way by pressing **{{{Esc}}}** and click on another one.14 The highlighted node can be locked (see [#Locksegment Lock segment]). 16 15 17 == Usage == 18 19 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. 20 21 Highlighted node can be locked (see [[#Locksegment]]). 22 23 When you add or move nodes, **they are not merged with existing nodes** as it happens in the [[Select|Select]] or [[Draw|Draw]] modes. You have to quit editing in ''Improve Way Accuracy'' mode and use [[MergeNodes|merge nodes]] tool or alternatives. 16 When 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. 24 17 25 18 === Move existing nodes === 26 27 Click in [Help/MapView Main view] where you think a node should be. The highlighted (nearest) node will be moved there. 19 Click in [wikitr:/Help/MapView Main view] where you think a node should be. The highlighted (nearest) node will be moved there. 28 20 29 21 ''Helper geometry: dashed red line - indicates a way after moved node'' 30 22 31 === Create new nodes [[ Image(source:trunk/images/cursor/modifier/addnode.png,middle,nolink,inline)]] (+{{{Ctrl}}}) ===23 === Create new nodes [[JOSMImage(cursor/modifier/addnode,middle,link=,inline)]] (+`Ctrl`) === 32 24 33 [[Image(JOSM-plugin-IWA-example.jpg, right)]]25 [[Image(JOSM-plugin-IWA-example.jpg,right,link=,margin-left=15)]] 34 26 35 Hold ** {{{Ctrl}}}** button and click - a new node will be added into highlighted segment.27 Hold **`Ctrl`** button and click - a new node will be added into highlighted segment. 36 28 37 29 ''Helper geometry: solid red line - indicates a way after new node'' 38 30 39 === Remove nodes [[ Image(source:trunk/images/cursor/modifier/delete.png,middle,nolink,inline)]] (+{{{Alt}}}) ===31 === Remove nodes [[JOSMImage(cursor/modifier/delete,middle,link=,inline)]] (+`Alt`) === 40 32 41 Hold ** {{{Alt}}}** button and click - the highlighted node will be deleted.33 Hold **`Alt`** button and click - the highlighted node will be deleted. 42 34 43 35 Please try to keep as much existing nodes as you can, because thus you keep their history. 44 36 45 **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.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.
