public VMAP2Shape()

Method Detail

writeShapeFile

public void writeShapeFile(java.lang.String shapeFileName)

Will load the properties set in the VPF2Shape object, fetch the OMGraphics from the VPF database, and write the shape file.

Parameters:

shapeFileName -

writeShapeFile

public void writeShapeFile(java.lang.String shapeFileName,
                           OMGraphicList graphics)

Write the shape file, assumes that the properties have been loaded and the graphics fetched from the VPF database.

Parameters:

shapeFileName - the file name to write the shapes into.

graphics - OMGraphics from VPF database to write to shape file.
