There was a abrasion problem on the north coast of the Serang District
Shoreline retreat is so big in the last 10 years. It is estimated that more
than 500 meters.
Shoreline Change make farm and residential in north coast of the
Serang District terancam
On Rencana Tata Ruang Wilayah” !RTRW "# $%&'() and Rencana
Strategis Wilayah Pesisir” doc*ment does not consider shoreline change
Therefore research thro*gh coastal ecosystem damage base shoreline
change is needed

+radiometric process aims to sharpen imagenary data#
that the result o classifcation can be more accurate/
+geometric process serves to 2ustiy the wrong coodinates#that the data map can be in the correct position/
