How to publish
a map

The only constraint to respect is not
adding rasters in the project . Therefore, you can
have
as many vector layers as you want, WFS layers and also
WMS layers.

Let’s consider a simple
example : a map with bicycle parkings in the city of Brest. By
clicking
on Cloud settings ( Extension -> Cloud -> Cloud
settings ) we get the following window :

Click Login and
fill
your
QGis
Cloud account .

You must have
a
database in the cloud to store the data of your projects
. The first time you are
forced
to
create
one
. Afterwards you can to
choose to create a new
one ( up to five bases are authorized ) or
to
use an existing one.

Go to the  Account
 tab. Click
the Create button to create a
database.

Once the base is created or selected
, you must load the data present
in
the QGis project . If you try
to publish your map without having
loaded the data , an error message will appear

Go to the  Upload Data tab.
Select
the layers and click Upload data.

To publish your map, go to  Map . You
have
two
buttons. The first one allows choosing a
background map for your map. The second publishes
the map in the cloud.

To set the base map, click Add background layer

As you can
see in the previous screenshot, you have
a
wide choice of background layers.

To finish the publication, just click on the Publish
Map button . You will
get
the cloud addresses of your map.

As you can
see you get a classic
web address , an address for mobile terminals
and a WMS address . What else?!!

You can consult the result
by
clicking
on the address obtained :
http://qgiscloud.com/SigEtTerritoires/velos

You can include
in
your
project
WFS or WMS connections . On the previous map , for
example, you can add the available tracks
cycling
tracks in a WFS server for the city of
Brest.

the result at http://qgiscloud.com/SigEtTerritoires/cyclos2
