To simply load and visualize data from a WFS, you can creata a model through
Using a proxy model
LuciadLightspeed uses proxy models for connections with OGC services. When added to a layer in a view, they automatically obtain the data (features, images …​) from the OGC service, making the service connection transparent to the user. The OGC client APIs create these proxy models by default, using a data source and model decoder.
To support customization possibilities, the OGC clients offer additional API related to the proxy model. Examples include the configuration of constraints on what data should be retrieved or which data exchange format should be used.
Creating a WFS proxy model
Use the class
TLcdWFSProxyModel.Builder to create and customize a WFS proxy model. The
required input parameters of the builder are a server and the name of the requested feature type.
Additional customization parameters are available, including the possibility to configure
the data exchange format.
The builder will return a
TLcdWFSProxyModel, which contains domain objects equivalent to
those that would be produced by
Optionally, users can specify a
TLcdOGCFilter to be applied to the feature
data, using the
setFilter method of the proxy model. This will restrict the
data that is retrieved from the WFS server.
