This demo is an overview of the standard functionalities that
are somehow visible for an end-user in Cartoweb. To get the most out of
it, read through this Help guide before starting to explore.

Data layers tab

Cartoweb supports an arbitrarily complex
hierarchy of layers, with indefinite path. The layers which are checked
and so selected, are displayed.

Once you have chosen your data,
click on the OK button, located beneath the tab, to update your
changes

Search tab

This tab allows you to move the center of the
viewing area on a desired location. You can choose this location by
three differents ways :
to
select a shortcut to a specific location,
to
entering the coordinates in the box X and Y (to start the search type on
the touch ),
to
do a search on the name. For it, please select the data on which you are
interested in, type the word or the begining of the word you think
correspond to a feature of the data and follow the instructions.

Outline tab

In Cartoweb, it is possible to freely draw
points, lines, rectangles and polygons on the map, and to attach labels
to them. These features are persistent: they survive panning or zooming.
This tab allows you to obtain informations on the drawn features and to
switch on the mask mode, in which everything but the outlined polygon is
masked, is provided too.

To draw the desired features, you
might use outline tools.

Query tab

Using the query tool, you can geographically
search for objects. Found objects are hilighted and their attributes are
displayed.
The queries are persistent (i.e. you can add new objects to already
selected objects). Note : only the layers which are specified
questionnable by the administrator of the website are concerned by the
query.

This tab allows you to parametrize your search. For each layers,
which can be interrogated, the following options can be set :
Hilight : allows to activate/desactivate
features hilight;
Attributes : if it's checked, the layers
attributes can be requested. Instead, only object IDs will be
returned;
Table : allows to display the query
result;
Union selection : when selecting a group of
objects, already selected ones are kept selected and no yet selected
ones are selected;
Xor : when selecting a group of objects,
already selected ones are unselected and no yet selected ones are
selected (defaut type);
Intersection : when selecting a group of
objects, only already selected are kept selected;
InQuery : if it's checked, you force query
to use this layer;
Mask : if it's checked, you apply a mask
instead of a simple selection. This don't work when using highlight
mecanism;

If "Query all selected layers" option is checked, the query will
handle all the questionnable layers

Print tab

Cartoweb is able to output a PDF document. You
can choose in this dialog tab, the elements you want to display
(scalebar, overview, query results, legend) and specify additional
options (format and resolutiion, orientation, title, note).

About tab

This tab give you some informations on the
data and the projections. All the data are royalty-free. Nima refers to
the datasource for the vector background and Gtopo30 refers to the
datasource for the raster background.

Mapping tools

Navigation interface
There are many possibilities to navigate on the main map, that is to
change the scale and the position
the
arrows surrounding the map;
the
dynamic (i.e. clickable) keymap;
the
navigation tools (zoom and pan), which are detailled below;
the
drop down menu "Scale";
the
various options in the "Search" tab.
The menu "Mapsize" is self- explanatory.

The Zoom In tool allows you to focus on a specific, smaller region of
the Europe area. Click the Zoom In button and then either click the map
near the center of the region you are interested in or click-and-drag a
rectangle surrounding the area. The Zoom In tool can be used multiple
times to move closer and closer to desired regions.
The Zoom Out tool allows you to focus on a larger area of the map
than is currently displayed. Click the Zoom Out button and then click
the map near the center of the larger region you are interested in. The
Zoom Out tool can be used multiple times to view larger and larger
regions.
The
Pan Map tool allows you to move the center of the viewing area without
changing the scale of the map. Click the Pan Map button and then click
and drag the map image to recenter it.
The
Zoom to Full Extents tool allows you to quickly reset the current map
view to the entire Europe area. There is no need to click on the map to
activate this tool - it is activated as soon as you click the Zoom to
Full Extents button.

Measuring tools
Distances and surfaces can be measured on the main map with the above
tools.

The internationalization tools
allow you to switch langage (Cartoweb uses gettext for the
translation).

 Access
to different elements of Cartoweb can be allowed or denied according to
who is currently using the application. Both functionnalities and data
may have access restrictions. For this demo, you can access to more
rights by using login 'demo' and password 'demo'. You can then access to
the train data and to the print fonctionnalities.

For more information, you can have a look to the Cartoweb
documentation
