Layer creation

Window for creating a new representation or a new layer

It is possible to create a new representation from a layer of geographic data or from a data table. All the options offered in this window create a new layer that will be added to the layer manager and to the map.

The functionalities offered are grouped into three categories:

• Representation: classic cartographic representations, dedicated to data visualization.
• Exploration: more advanced statistical representations, dedicated to data exploration, and whose cartographic results should be used with caution due to the exploratory nature of these representations.
• Geo-processing: geographic data processing, useful for preparing data for cartography.

The available functionalities depend on the type of data (geographic or tabular) selected and the type of variables contained (stock, ratio, etc.) in the data.

The grayed-out functionalities indicate that the option is not available for the data contained in the layer in question. If you think the option should be available, check that the data is correctly typed (see Field typing).

After choosing the type of representation, it is necessary to choose the various parameters specific to the chosen representation (for example, the field to represent, the type of discretization, etc.).
