compared ESRI's File Geodatabase and Google's KMZ file formats, against their respective web viewers: The CLIWOC dataset has almost 290,000 points, and is almost 250Mb Geodatabase. The location parameters were extracted into a File Geodatabase and compressed to 10 Mb. These are displayed by 25 year time-slices and for Captains Cook and de la Perouse. This file geodatabase is easily downloaded and consumed by ArcGIS Explorer. For comparison, a KMZ file was exported directly from the ESRI MXD file.

His original intent was to claim it for the French king, and he almost
took a young Napoleon as his surveyor...
Think of the consequences had Napoleon died young!
