Vespucci Introduction

Vespucci is a full featured OpenStreetMap editor that supports most operations that desktop editors provide. It has been tested successfully on googles Android 2.3 to 6.0 and various AOSP based variants. A word of caution: while mobile devices capabilities have caught up with their desktop rivals, particularly older devices have very limited memory available and tend to be rather slow. You should take this in to account when using Vespucci and keep, for example, the size of the areas you are editing to a reasonable size.

First time use

On startup Vespucci shows you the "Download other location"/"Load Area" dialog. If you have coordinates displayed and want to download immediately, you can select the appropriate option and set the radius around the location that you want to download. Do not select a large area on slow devices.

Alternatively you can dismiss the dialog by pressing the "Go to map" button and pan and zoom to a location you want to edit and download the data then (see below: "Editing with Vespucci").

Editing with Vespucci

Depending on screen size and age of your device editing actions may either be accessible directly via icons in the top bar, via a drop down menu on the right of the top bar, from the bottom bar (if present) or via the menu key.

Downloading OSM Data

Select either the transfer icon Transfer or the "Transfer" menu item. This will display seven options:

The easiest way to download data to the device is to zoom and pan to the location you want to edit and then to select "Download current view". You can zoom by using gestures, the zoom buttons or the volume control buttons on the telephone. Vespucci should then download data for the current view. No authentication is required for downloading data to your device.


Lock, unlock, "tag editing only"

To avoid accidental edits Vespucci starts in "locked" mode, a mode that only allows zooming and moving the map. Tap the Locked icon to unlock the screen. A long press on the lock icon will enable "Tag editing only" mode which will not allow you to create new objects or edit the geometry of objects, this mode is indicated with a slightly different white lock icon.

Singe tap, double tap, and long press

By default, selectable nodes and ways have an orange area around them indicating roughly where you have to touch to select an object. You have three options:

It is a good strategy to zoom in if you attempt to edit a high density area.

Vespucci has a good "undo/redo" system so don't be afraid of experimenting on your device, however please do not upload and save pure test data.

Selecting / De-selecting (single tap and "selection menu")

Touch an object to select and highlight it. Touching the screen in an empty region will de-select. If you have selected an object and you need to select something else, simply touch the object in question, there is no need to de-select first. A double tap on an object will start Multiselect mode.

Note that if you try to select an object and Vespucci determines that the selection could mean multiple objects (such as a node on a way or other overlapping objects) it will present a selection menu: Tap the object you wish to select and the object is selected.

Selected objects are indicated through a thin yellow border. The yellow border may be hard to spot, depending on map background and zoom factor. Once a selection has been made, you will see a notification confirming the selection.

You can also use menu items: For further information see Node selected and Way selected.

Selected objects: Editing tags

A second touch on the selected object opens the tag editor and you can edit the tags associated with the object.

Note that for overlapping objects (such as a node on a way) the selection menu comes back up for a second time. Selecting the same object brings up the tag editor; selecting another object simple selects the other object.

Selected objects: Moving a Node or Way

Once you have selected an object, it can be moved. Note that objects can be dragged/moved only when they are selected. Simply drag near (i.e. within the tolerance zone of) the selected object to move it. If you select the large drag area in the preferences, you get a large area around the selected node that makes it easier to position the object.

Adding a new Node/Point or Way (long press)

Long press where you want the node to be or the way to start. You will see a black "crosshair" symbol. If you want to create a new node (not connected to an object), click away from existing objects. If you want to extend a way, click within the "tolerance zone" of the way (or a node on the way). The tolerance zone is indicated by the areas around a node or way.

Once you can see the crosshair symbol, you have these options:

Simply touch the screen where you want to add further nodes of the way. To finish, touch the final node twice. If the final node is located on a way or node, the segment will be connected to the way or node automatically.

You can also use a menu item: See Creating new objects for more information.

Improving Way Geometry

If you zoom in far enough you will see a small "x" in the middle of way segments that are long enough. Dragging the "x" will create a node in the way at that location. Note: to avoid accidentally creating nodes, the touch tolerance for this operation is fairly small.

Cut, Copy & Paste

You can copy or cut selected nodes and ways, and then paste once or multiple times to a new location. Cutting will retain the osm id and version. To paste long press the location you want to paste to (you will see a cross hair marking the location). Then select "Paste" from the menu.

Efficiently Adding Addresses

Vespucci has an "add address tags" function that tries to make surveying addresses more efficient. It can be selected

House number prediction typically requires at least two house numbers on each side of the road to be entered to work, the more numbers present in the data the better.

Consider using this with the "Auto-download" mode.

Adding Turn Restrictions

Vespucci has a fast way to add turn restrictions, if necessary it will split ways automatically and, if necessary, ask you to re-select elements.

Vespucci in "locked" mode

When the red lock is displayed all non-editing actions are available. Additionally a long press on or near to an object will display the detail information screen if it is an OSM object.

Saving Your Changes

(requires network connectivity)

Select the same button or menu item you did for the download and now select "Upload data to OSM server".

Vespucci supports OAuth authorization and the classical username and password method. OAuth is preferable since it avoids sending passwords in the clear.

New Vespucci installs will have OAuth enabled by default. On your first attempt to upload modified data, a page from the OSM website loads. After you have logged on (over an encrypted connection) you will be asked to authorize Vespucci to edit using your account. If you want to or need to authorize the OAuth access to your account before editing there is a corresponding item in the "Tools" menu.

If you want to save your work and do not have Internet access, you can save to a JOSM compatible .osm file and either upload later with Vespucci or with JOSM.

Resolving conflicts on uploads

Vespucci has a simple conflict resolver. However if you suspect that there are major issues with your edits, export your changes to a .osc file ("Export" menu item in the "Transfer" menu) and fix and upload them with JOSM. See the detailed help on conflict resolution.

Using GPS

You can use Vespucci to create a GPX track and display it on your device. Further you can display the current GPS position (set "Show location" in the GPS menu) and/or have the screen center around and follow the position (set "Follow GPS Position" in the GPS menu).

If you have the later set, moving the screen manually or editing will cause the "follow GPS" mode to be disabled and the blue GPS arrow will change from an outline to a filled arrow. To quickly return to the "follow" mode, simply touch the arrow or re-check the option from the menu.

Notes and Bugs

Vespucci supports downloading, commenting and closing of OSM Notes (formerly OSM Bugs) and the equivalent functionality for "Bugs" produced by the OSMOSE quality assurance tool. Both have to either be downloaded explicitly or you can use the auto download facility to access the items in your immediate area. Once edited or closed, you can either upload the bug or Note immediately or upload all at once.

On the map the Notes and bugs are represented by a small bug icon Bug, green ones are closed/resolved, blue ones have been created or edited by you, and yellow indicates that it is still active and hasn't been changed.

The OSMOSE bug display will provide a link to the affected object in blue, touching the link will select the object, center the screen on it and down load the area beforehand if necessary.


Besides globally enabling the notes and bugs display you can set a coarse grain display filter to reduce clutter. In the "Advanced preferences" you can individually select:
