Description
Abstract This dataset consists of GPS data from Cocos (Keeling) Island visitors who track their travels around the island group using GPS units.  This is useful to test the accuracy of aerial imagery and road \ track location data.  The inter-island ferry is also being tracked to provide location data on the various wharfes and landing sites that are used as well as the local shipping channels.  The GPS measurements may not be highly accurate and have infrequent points around corners.  However, over many traverses the positional accuracy of the Cocos GIS datasets is proving to be better than expected.

Data Quality
Lineage The GPS track data is derived from direct downloads from various GPS recievers using Garfield Pro or OZI explorer software.  Data has been recorded in MGA(UTM Zone 47) projection so no dataset conversion has been necessary.
Positional Accuracy This data set is only intended to verify the positional accuracy of imagery, exsisting road and track data etc. and have proven adequate for this purpose.
Attribute Accuracy The GPS manufacturers claim an accuracy of +/- 5m RMS.
Logical Consistency Consistency.
Completeness This is an ongoing data set and over time will yield an up to date data set of road, track, wharf and ferry traffic channel locations for the Cocos (Keeling) Islands.
