Method Detail

createFeatureLayer

public static Layer createFeatureLayer(String name)
                                throws Exception

creates an empty feature layer with EPSG:4326 as default coordinate reference system. All data that will be added to the layer will be converted to the EPSG:4326 coordinate reference system if no other CRS is set.

Parameters:

name - of the layer

Returns:

the layer with epsg:4326 set as crs

Throws:

Exception

createFeatureLayer

public static Layer createFeatureLayer(String name,
                                       CoordinateSystem crs)
                                throws Exception

creates an empty feature layer. All data that will be added to the layer will be converted to the submitted coordinate reference system if no other CRS is set.

Parameters:

name - of the layer

crs - of the crs

Returns:

the feature layer with given crs and name.

Throws:

Exception

createFeatureLayer

public static Layer createFeatureLayer(String name,
                                       CoordinateSystem crs,
                                       FeatureCollection fc)
                                throws Exception

creates a complete feature layer. If the CRS of the geometries contained within the submitted feature collection are not the same as the submitted CRS all geometries will be converted to the submitted CRS.

Parameters:

name - of the feature layer

crs - of the crs of the feature layer

fc - to get the geometries from

Returns:

to the Layer created from given paraemters.

Throws:

Exception

createRasterLayer

public static Layer createRasterLayer(String name,
                                      GridCoverage raster)
                               throws Exception

creates a raster layer. The required CRS is contained within the GC_GridCoverage object

Parameters:

name - name of raster layer

raster - the raster to create the layer from.

Returns:

the raster layer.

Throws:

Exception

createRasterLayer

public static Layer createRasterLayer(String name,
                                      GridCoverage raster,
                                      GetMap request)
                               throws Exception

Parameters:

name -

raster -

request -

Returns:

the new layer

Throws:

Exception

createTheme

public static Theme createTheme(String name,
                                Layer layer,
                                UserStyle[] styles)

creates a theme with a name, a Layer containing the themes data and an array of styles to be known by the Theme

Parameters:

name - of the theme

layer - the layer to create the theme from

styles - the styles to set

Returns:

the created theme from given parameters

createTheme

public static Theme createTheme(String name,
                                Layer layer)

creates a theme with a name, a Layer containing the themes data and an array of styles to be known by the Theme

Parameters:

name - of the theme

layer - to use

Returns:

the created theme from given parameters

createMapView

public static MapView createMapView(String name,
                                    Envelope boundingbox,
                                    CoordinateSystem crs,
                                    Theme[] themes,
                                    double pixelsize)
                             throws Exception

creates a MapView with a name, a boundingbox describing the area coverd by the MapView, a CRS and n Themes.

Parameters:

name - of the mapview

boundingbox - of the mapview

crs - of the mapview

themes - of the mapview

pixelsize - used for rendering

Returns:

the mapview created from given parameters

Throws:

Exception
