Constructor Detail

QGisWriter

public QGisWriter(String crs,
                  String workingDir)

Creates a new instance of a QGis project file (*.qgs) writer. Coordinate reference system and working directory are mandatory for writing the file. Layers have to be added separately with the method addLayer. If no layers were added, the writer creates an empty project file.

After calling the constructor you have to set the envelope (starting view) manually.

Parameters:

crs - coordinate reference system of the network / spatial data

workingDir - the directory in which all generated files (shapefiles, qgs file) are put.

Method Detail

addLayer

public void addLayer(QGisLayer layer)

Adds a new layer to the layers list.

Parameters:

layer - the layer you want to add

addLayer

public void addLayer(int position,
                     QGisLayer layer)

Adds a new layer to the layers list at the specified position.

Parameters:

position - the index you want to add the layer at

layer - the layer you want to add

write

public void write(String filename)

Specified by:

write in interface org.matsim.core.api.internal.MatsimWriter

changeWorkingDirectory

public void changeWorkingDirectory(String workingDir)

getLayers

public List<QGisLayer> getLayers()

getEnvelope

public org.locationtech.jts.geom.Envelope getEnvelope()

getWorkingDir

public String getWorkingDir()

setEnvelope

public void setEnvelope(org.locationtech.jts.geom.Envelope envelope)

Sets the starting view on the map when opening the project file.

Parameters:

envelope - with minx, miny, maxx and maxy coordinates of the starting view

getSRS

public SRS getSRS()

Returns:

The spatial reference system that was created for the project file

getUnit

public QGisConstants.units getUnit()

setUnit

public void setUnit(QGisConstants.units unit)

getTitle

public String getTitle()

setTitle

public void setTitle(String title)

getProjectname

public String getProjectname()

setProjectname

public void setProjectname(String projectname)
