Abstract |
This map shows signposted height clearance signs of overhead structures on arterial roads on Tasmania's road network. This dataset indicates safe clearance between the road surface and overhead structures and is intended to be a planning tool to assist heavy vehicle operators and drivers to plan their routes. It is important to note that (i) other low clearance items, that may be present on the network, such as transmission lines and trees, are not displayed on this map, and (ii) In the event of a discrepancy between a signposted clearance shown on the structure and this map, the signposted clearance on the structure is the correct legal clearance and takes precedence. Height clearances expressed in 0.1m increments are shown by location symbols on the map. The different colours of the symbols are height groupings as shown in the key. |

Lineage Statement |
The data was sourced from reviewing existing road crossing records in the Road Information Mgt System (RIMS) and updated with council records on road crossings with clearances in Tasmania. The data was validated by cross checking against previous records, road videos (Dept State Growth) and Google Street View.
Updates to the clearances are made not planned. |

Lineage Description |
Positional Accuracy: As per LIST Transport segments (1: 25,000). Accuracy of this layer is +/- 2m in urban areas and +/- 10meters in rural and remote areas.
Attribute Accuracy: Attributes are estimated to be 99% correct. All codes and labels for the Network are validated. Please advise if errors found.
Completeness: 80% complete. The data lists heights under overhead structures that are less than 5.5m in height. Roads with overhead clearance greater than 5.5m are not depicted.
