Editor JOSM

• JOSM is the Java OpenStreetMap editor

• Tool to download and edit maps created by the OpenStreetMap community

Editing Open Street Maps: steps

• Step 1: Download– Get the current map data from OSM

• Step 2: Edit– Modify the map using GPS, Walking Papers and

notes as a guides.• Step 3: Save

– Save changes to OpenStreetMap.

Prepare JOSM

• Open JOSM• Load your gpx file, or walking paper map by

– Menu>>File>>Open..• JOSM supports *.gpx,*.osm,*.jpg etc formats

Download OSM Data

• Before we edit, download existing OSM data of the area from OpenStreetMap

• To download we need to be connected to the internet

area of map for editing.• After getting the appropriate size and require

location, click “Download” from download window

• Finally the JOSM will get the data and open it in your map window.

The download window appears as:

Edit:

• Using different drawing tools, you can change, move, resize, rename, delete, add different features in the map to correct them

• Digitize the GPS tracks, way points using draw tools

• For every objects, select the appropriate presets and name them

Upload Changes:After finished making changes, improvements, corrections in the OSM map,• Go to top menu ,Click “File”>>”Upload Data”• This open up the upload window, then click “Upload Changes”• If is your first time to change OSM, it will ask for your

username and password• Click “Authenticate”, after providing username and password.• Note: you need to be connecte to internet to save changes to

OSM• Finally, you can see your apply changes in openstreetmap.org

Keyboard Shortcuts: JOSM• s – Choose the Select tool• a – Choose the Draw tool• z – Choose the Zoom tool• + (plus) – Zoom in• - (minus) – Zoom out• p – Split way• c – Combine way• o – Align in circle• l – Align in line• q – Orthogonalize (make a shape square)
