Abstract
This dataset contains point, line and polygon data of the marine environment surrounding the Cocos (Keeling) Islands. It includes coastlines, bathymetric contours, coral outcrops and other features. Coverage extends to the whole of Cocos Keeling Isalnds. The themes have been grouped so as to increase the ease of use of the data. The individual themes have been grouped into the following shapefiles: Infralin.shp - Infrastructure lines Boundlin.shp - Boundary lines Marinelin.shp - Marine lines Surveylin.shp - Survey lines Islandlin.shp - Island outlines Marineply.shp - Marine polygon Islandply.shp - Island polygon Boundply.shp - Boundary polygon These shapefiles retain all spatial and non spatial data as supplied to GA. To view the sample of the marine environment with the legend click here. In December 2003 GA projected the data to UTM (WGS84) zone 47 using Arcview.

Lineage
Not known prior to AGSOs receipt of the data (no metadata is available). Data was received as ArcInfo Export files. AGSO converted the data to Shapefile format. AGSO projected the data to CKIG92 with a coordinate shift to match the Cadastre (assuming it was received as UTM Zone 47 WGS72). The multitude of individual shapefiles were checked and those of similar themes were then grouped to provide a smaller set of shapefiles, thus making them more usable. The North Keeling atoll was translated and warped to more accurately match the orthophotography. The amount of translation and compression required can be found in the Cocos GIS documentation. Line themes were built into polygons to allow areas to be queried. In December 2003 GA projected the data to UTM(WGS84) zone 47
