[1] [2] To the 12 nautical-mile boundary is Australia's territorial waters.

Shapefile (GIS) dataset of every sealed and unsealed road in the state, and has been recently created and updated (2013). Data includes road names, route numbers, and class (Highway, Arterial, etc.). The license is CC-BY-3.0-AU, so it can be used to create maps.
In spatial analysis, four major problems interfere with an accurate estimation of the statistical parameter: the boundary problem, scale problem, pattern problem (or spatial autocorrelation), and modifiable areal unit problem. [1] The boundary problem occurs because of the loss of neighbours in analyses that depend on the values of the neighbours.
GADM, the Database of Global Administrative Areas, is a high-resolution database of country administrative areas, with a goal of "all countries, at all levels, at any time period."
Shapefile (Esri 1992–present) As the GIS industry grew to incorporate more casual users, the inherent complexity of the coverage data structure became a concern. When Esri released ArcView GIS 2.0 in 1992, it introduced the new shapefile format for vector data. This was a much simpler data model, eliminating features such as topology, but was ...
