During writing, an index will also be created. To create a ShapefileWriter, do something like<br> <code> GeometryCollection geoms; File shp = new File("myshape.shp"); File shx = new File("myshape.shx"); ShapefileWriter writer = new ShapefileWriter( shp.getChannel(),shx.getChannel() ); writer.write(geoms,ShapeType.ARC); </code> This example assumes that each shape in the collection is a LineString.<P><P><DL><DT><B>Author:</B></DT> <DD>jamesm, aaime, Ian Schneider</DD><DT><B>See Also:</B><DD><A HREF="../../../../../org/geotools/data/shapefile/ShapefileDataStore.html" title="class in
