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.
The shapefile format is a geospatial vector data format for geographic information system (GIS) software. It is developed and regulated by Esri as a mostly open specification for data interoperability among Esri and other GIS software products . [ 1 ]
Shapefiles : are a data exchange format created by ESRI and one of the most widely used GIS/geodata formats. One "shapefile" usually include four different files : .shp, .shx, .dbf, .prj. First three files must all be present in order to use the data. Each shapefile can hold only one geometry type.
For example, the field is a generic conceptual model of geographic phenomena, the relational database model and vector are generic logical models, while the shapefile format is a generic physical model. These models are typically implemented directly info software and GIS file formats.
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."
Australia's exclusive economic zone (EEZ) was declared on 1 August 1994 and extends from 12 to 200 nautical miles (22 to 370 km) from the coastline of Australia and its external territories, except where a maritime delimitation agreement exists with another state. [1] [2] To the 12 nautical-mile boundary is Australia's territorial waters.
In 2008, data in shapefile format was published. Please note that shapefiles are not topological, therefore may create slivers when comparing TIGER/Line boundaries. This mismatch was not possible when the census TIGER files were available in ASCII format that was topological unlike shapefiles.
