RDB_Authority is a linear representation of roads on Public Land categorised by managing agency. Generally, it does not include roads managed by local governement or VicRoads. Determination of the managing authority of roads is by agreement with relevant parties and verified by each regional manager within DSE. When a road is assigned to a managing authority it implies responsibility for matters relating to the road, including management and maintenance. The underlying linear data is derived from Vicmap Transport Roads. Authority categories are assigned through a relational database connection and the arcs grouped to simplify data geometry. DSE's ROADS database contains information relating to DSE-managed road assets.

TR_ROAD_REGISTER forms the basis of the road register for Victoria. Road segements (TR_ROAD) are grouped by road name, road type, road suffix and locality using the TR_ROAD_LOCALITY_SECTION and TR_ROAD_LOCALITY tables to create a single line feature for each unique combination of values. This dataset compliments TR_ROAD. Where a road segement has multiple names, TR_ROAD_REGISTER will have multiple overlappling road lines while TR_ROAD will have one road with multiple names. TR_ROAD_REGISTER facilitates road searching and efficent road name lablelling. In addition the dataset has an atttribute MIN_CLASS_CODE which is the the minimum CLASS_CODE for all TR_ROAD road lines that have the unique cominbination of identifer vaules. For example, if the road segments associated with the unique road identifer have CLASS_CODES of 0 (Freeway), 1 (Highway) and 2 (Arterial), the MIN_CLASS_CODE of that road will be 0 (Freeway). This value faciliates feature filtering at different scales and symbolisation.

This layer is a superset of the Vicmap TR_ROAD dataset; the latter dataset that is part of Vicmap Transport. It is an extensive digital road network - line features delineating state wide road network. In addtion to all features contained in TR_ROAD; bridges, connectors, footbridges, foot tracks, roads, roundabouts & tunnels, it also includes paper roads to provide a complete road name register. Paper roads (feature_type_code 'paper_road') exist only on paper, such as a plan of subdivision, and are unlikely to be ever built due to planning restrictions. However, some councils hold addresses and property information against these paper roads. Currently it is not possible to differentiate between addresses who have an incorrect road name and paper road names. Attribution includes names, alias names, feature_type, class, direction, locality, unique feature identification, suburb/locality. See documentation for Vicmap TR_ROAD for most information about this dataset.

Regions showing the extent of mineral Retention Licences currently lodged with Earth Resources Regulations. The boundaries are derived from a combination of entering graticular boundaries (exact MGA co-ordinates) and digitizing along areas of land status (Earth Resources version of plm25) which are unable to be mined or explored. Refer to the Mineral Resources (Sustainable Development) Act (MRSDA) 1990 for more detail.
