Challenged by this request, see:
http://www.openstreetmap.org/browse/changeset/1429273
http://www.openstreetmap.org/browse/way/35468493
http://www.openstreetmap.org/browse/way/35468489

The problem with the default Landsat is the extensive cloudcover, so I
downloaded a newer image (free and public domain) taken March 2009.

This image have fewer clouds but the edges (which Caliraya was
located) has data gaps (nasira last 2002 yung satellite).
I digitized the shoreline in QGIS (FOSS gis app) and converted the
shapefile to gpx using GPSbabel (FOSS GPS data converter).
Load in JOSM edited unconnected nodes, added more detail along the
previous image gaps.  Add tags:
natural=water
name=
source=

Add a multipolygon relation for islands.  Upload.


A lot more improvement is needed (mapping party) but it should look
better by the next render.

Good night!
