DEECA Roads database - Class codes

dataset: RDB_CLASS
Class codes is a linear representation of roads on Public land defined by road class. Class codes range from 5A to 5E and fall into the national 'forest roads' category. Class codes describe a road by its physical characteristics and usage. The prefix 5 is related to the Austroads National Functional Road Classification categories. A DSE road's class code will determine it's maintenance regime and is used in asset management tools. The underlying linear data is derived from Vicmap Transport Roads. Classes are assigned through a relational database connection and the arcs grouped to simplify data geometry. DSE's ROADS database contains information relating to DEECA-managed road assets. It is envisaged that the database be accessible through GIMS asset management system.

Supplemental Information
History: Original data compiled in 2000 from marked up maps provided by district staff within DEECA. Relationship to other Datasets: This layer is derived from Vicmap Transport (spatial) and DEECA road system (attributes) Relationships are dependant on presence of the DEECA route number, or road ID. Current Design Issues: All data is derived from data sourced by Dynamic Segmentation functionality in ArcInfo Relies on Workstation scripts to generate output featureclasses Related Documents: None Refer to documentation for key databases and major data revisions with DSE roads administrator.
