PuntoGPS documentation

It shows the locations of online users as a blue dot (a lighter one is your position, i.e. that of the device with the same IP of the browser used to view the map):

Hovering or clicking on a user position dot will pop up its user status, location and last update time.

The map service can also be used to view/edit uploaded tracks by putting the suffix:

Pan-zoom controls

The default map navigation is set to "mouse/touch", that is you can move around dragging, and zoom with the mouse wheel (or the usual corresponding gesture on touch devices).

You can stop this behaviour by clicking on the button:

hand

the button will turn into:

hand

and the pan-zoom controls will show-up,

pan-u pan-d pan-l pan-r zoom-in zoom-out

allowing you to pan and zoom by a single click on each button.

Pause

Users locations are updated issuing a query at a fixed configurable interval (10 seconds in my server) to the server (few tens of bytes per query).
You can pause it by clicking the pause button: the button will turn into

play

which you can click to resume updates.

Online users

Shows the list of current online users with their status and last hit time.

users

By clicking the blue dot on the right of the user status the map will center on the user location.

You can also "chase" a user by checking the box on the right of its status: the dot will turn red and the map will center at that user position on each update.

chase

To hide the list click the users-list button again.

Tile layers

Shows the list of available tile layers to change the map view.
the default is OpenCycleMap, you can change it by checking the box on the right of the layer name:

Track edit tools

To load a track you must know its id and write it as a query argument named "track" to the service url, e.g.:


				http://lnx.utillyty.eu/puntogps?track=1

(the track must have been previously uploaded with the PuntoGPS app)

By clicking on the map edit tools buttons a few filters options are shown to apply to your map:

Distance threshold: "examines each point in a track, in order, and discards every trackpoint that is not at least treshold (m) far from the last non-discarded point" (this is my javascript implementation, I borrowed the idea from: http://www.gpsvisualizer.com/tutorials/track_filters.html )
Ramer Douglas: javascript implementation of the wide spread Ramer–Douglas–Peucker algorithm (the kink (m) corresponds to the "ε" in the Wikipedia explanation).
Manual edit: For fine tuning, you can manually drag each point.
You can delete a point by clicking the <del> button or the "d" key on your keyboard while hovering the point with the mouse.
No point can be added to the track.

Default value for filters parameters are set optimally for a bike travelling at 15/20 km/h.
You can make as many try as you like with different values, and use the <Reset> button to restore the original track.

Once you're done you must use the <Save> button to store the new track: a new track id will be assigned to the track (a dialog will show it up) and you must use this new id to later view/share it (this is by design as there is no user-account and anyone can edit the track).

You can use the export as GPX link to download your track as a GPX file.
