Some room for improvement for Java map, done by ITB-1 & ITB-2, are indicated on the picture above. Please improve them using: 1) a new scanned map with given georeference points; 2) use the merge Java-Bali shape file; 3) improve the accuracy of the polygon; 4) don't leave gaps between polygons by using merge and clip facility when making polygons.
Cheers, Herman
