1. INTRODUCTION This guideline defines the string and model naming conventions for all survey, mapping and design data used or developed for projects undertaken for Main Roads. MX is the standard design software package used within Main Roads. A "genio" ascii file is the general format used for the transfer of data. The initial headers within this genio file (delete, create and genio) enable users to assign a model name that describes the project location and coordinate grid. When imported into MX these headers create the model name and the associated genio strings are placed in the defined model. In addition the name of the genio file is to also reflect the project location and coordinate grid. A sample MX genio file and a guideline on the naming convention for the model name and associated strings are detailed below. The logical naming of files is particularly important where alternate formats are used to provide information (Microstation, AutoCAD, Arcinfo export etc.), that don't have the functionality of defining a model name. In addition to the use of logical naming conventions all survey, mapping and design data shall be accompanied by a Metadata Statement, Statement, which will include sufficient information to adequately define: Lineage Positional Accuracy Attribute Accuracy Logical Consiste Consistency ncy Completeness of Data

2. FILE NAMING CONVENTION Logical file names in conjunction with a suitable metadata statement should be used to provide sufficient information to clearly identify the data. An exampl e wh ere a logical name i s not used would be: survey.gen - The only information a user is likely to impart from this name is that it is an MX genio file (extension .gen) of a survey. A more logical name w ould be: GNH_200_220.gen - Logically this would identify that it is a file containing digital information for Great Northern Highway from 200-220 SLK. The associated metadata statement would identify whether it is survey, design etc.

3. MODEL NAMING CONVENTION Careful selection of model names shall be taken to avoid confusion when working on large projects with multiple interchanges or intersections. Uniform naming conventions will enable designers to move easily from one project to another. Model names shall contain no more than 28 letters including spaces. Wherever possible the name of a project zone shall be included in the model name.

3.1 Design Models For design purposes, separate models shall be created for intersections or each interchange. The main alignment and related strings shall be designed in a separate model. On completion of the design process all relevant strings shall be copied into a master design model for sectioning, volumes calculations, reporting for construction and preparation of final drawings. All redundant strings should be deleted and all relevant strings should have discontinuities introduced where necessary, after being copied into the master design model. The master design model shall contain only strings required for construction. Naming convention formats for typical design models should be as per the following example, where PCG94 is the local grid used: DESIGN CONCEPT PCG94 - Concept design model DESIGN FINAL PCG94 - Final design model DESIGN ULTIMATE PCG94 - Ultimate design model DESIGN CONCEPT "intersection/interchange name/number" PCG94 - Concept intersection/interchange design SECTIONS CONCEPT PCG94 - Concept sections model SECTIONS FINAL PCG94 - Final sections model SECTIONS ULTIMATE PCG94 - Ultimate sections model SECTIONS CONCEPT "name/number" PCG94 - Concept intersection/interchange sections CADASTRAL PCG94 - Cadastral model SERVICES PCG94 - Services model

These model names are provided as a guide and can be varied to suit the requirements of particular projects. Model names should however be selected logically enabling other designers to access the data easily.

3.2 Survey and Mapping Models 3.2.1 Detail Survey Models Care should be taken when defining MX model names to ensure that the name is relevant to the data content, survey location and project zone. For example a detail survey of the intersection of Wellington Street and William Street, Perth, where PCG94 is the local grid used could be called: WELLINGTON WILLIAM SURVEY PCG94 Whereas a stripped ground survey for a section of the Graham Farmer Freeway, where PCG94 is the local grid used could be called: GFF LAKE TO WILLIAM STRIP PCG94 To assist in the design process, individual detail surveys and thus model names shall be created for the following: Topographic Survey Boundary Polygon For Mapping Projects (67-08-44 Digital Photogrammetric Mapping ) Detail Relief Spot Heights Text Boundary Polygon Cadastral Services Contours Audit Where digital information is supplied to other internal or external areas, documentation must also be provided to clearly identify what is being supplied. For further information pertaining to this refer to the following guideline: Data Purchase or Supply Guidelines. Detail survey models shall have at the minimum, the coordinate zone used in the model name. Naming convention formats for typical survey and mapping models where, PCG94 is the local grid used, should be as per the following example:

Model names should however be selected logically enabling other designers to access the data easily.

4. STRING NAMING CONVENTION 4.1 Design Strings Surfaces and features are represented as a group of strings with string labels consisting of four alphanumeric characters. Main Roads has adopted the National MX string naming convention and feature set. The string names, detailed at section 4.3 shall be used for all Main Roads design projects and are compatible with the default MXRoad string naming convention and feature set. The labels detailed at section 4.3 are the first two characters of the string label. Consideration should be given to defining the 3rd character of string labels to particular intersections and/or interchanges. For example "ES10" would refer to a shoulder string located at intersection number 1 on the left hand side. This particular naming convention allows strings to be grouped according to the intersection(s) where they are situated, making it easier for other MX users and designers to locate a design string when necessary. String label "TTTT" is a special string and should not be used. The Road and Traffic Engineering Branch has developed a feature design style set meeting the requirements of the National String Naming Convention. This feature set also conforms to the Main Roads Drawing Presentation Guideline.

4.2 Survey and Mapping Strings A dig ital terrain model can b e represe nted by a nu mber of string or point features with e ach feature label consisting of four a lphanumeri c characters. Main Roads has developed a detailed list of string naming conventions to be used in all Main Roads survey and mapping projects. The feature coding for topographical surveys are detailed in the 67-08-43 Digital Ground Survey. All feature labels shall be used in strict accordance with this list. Undergroung utilities surveys codes are detailed in 67-08-121 . In the case of mapping projects, not all codes are used. For a list of feature codes applicable for mapping projects refer to Appendix B of 67-08-44 Digital Photogrammetric Mapping . Where a particular unique feature does not have a corresponding feature code and is considered to be significant, it shall be captured and supplied in an appropriate MX format, with a unique feature code. On registration and lodgement of the digital data, the associated documentation shall include a summary of all non-standard strings captured, including the MX code used.

4.3 Main Roads String Naming Convention The Main Roads String Naming Convention has been based on the National String Naming Convention. The following table gives standard string labels used for naming of strings in design models. The characters listed below represent the first two string label characters. The Main Roads String Naming Convention adopts different alphanumeric characters for left and right offsets. These characters are placed in the 4th field of the string label: Left hand side - 0 to 9 and A to H Right hand side - I to Z
