Once completed it will contain information covering the following areas.
Data storage and access has obvious corporate impacts and it is envisaged that a number of the issues addressed in the following information will be formulated into policy statements and presented to Corporate Executive for endorsement.
The ability to effectively manage the data is being further pressured by the development of Term Consultancy Contracts, where there is a need not only to access existing data but also be able to store and manage captured information, developed and lodged as part of the contract deliverable's.
To address these issues a review is being undertaken by personnel from the Road & Traffic Engineering Branch who will liaise with each Region to review the data the Region currently holds and restructure the way that this data is stored and accessed.
This expected outcomes of this review will see:
It is hoped that this review and recommended approach to the management of digital design and survey data will be completed by July 2001. On completion of the review the recommendation will be forwarded to Corporate Executive for endorsement.
Digital data is a valuable and costly (to capture) asset that needs to be stored and effectively managed. To maintain the currency of this asset all digital data related to the design and survey process of road and bridge construction shall be stored. This includes:
All design models and input files including:
To facilitate the management of this stored data, all data shall have a related Metadata Statement. For further details refer to Metadata Requirements.
Depending on the type of contract being undertaken, there are varying requirements as to the type of digital data to be stored. For further details refer to Data Lodgement.
In essence a simple user interface will be available where the Main Roads officer lodging the information will place the internal or consultant supplied data in a designated directory on a shared server. That officer will then be requested to complete an easy to use windows based Metadata tool, which will require particular information to be entered so that the data can be stored and registered in a logical and consistent manner. The type of information that will be required is:
Once placed in this designated directory a notification will be sent to the Data Manager (Road and Traffic Engineering Branch) who will verify the Metadata and place the fully indexed data on a server to allow online access and backup.
Because of time and delivery constraints placed on projects an important aspect of the development of the methodology of storing digital data is to make it as user friendly as possible thus encouraging Project Mangers to ensure digital design and survey is lodged and stored in accordance with contract obligations.
Until the completion of the review any design or survey information that needs to be lodged and stored in accordance with contract requirements can be lodged with the
Data Manager - Road & Traffic Engineering
When supplying the information the minimum Metadata as described above is required.
Although these indexes are not yet complete, a summary of what digital information is available is detailed below.
Map the following network share \\dacsrv01\spatialsrv
IMAGES - The following digital images are found under the directory "images"
NOTE : Georeferenced images are images that are spatially correct and any coordinated information can be overlayed on the image by using an appropriate software package. For example Arcview. All images are in Zone 50 AMG coordinates. Street Smart touring maps are expected to be online shortly
MAPPING - in the directory "mapping indexes" the following Arcview project files are available:
Until the indexes are completed, for any queries as to what data is available or queries on the above guideline please contact the Data Manager - Road & Traffic Engineering.
The information is a small subset of what is available from State Government Agencies and selected private industry companies through the Western Australian Land Information System (WALIS).
To review the types of Land Information available through WALIS the data can be sourced from Interrogator On-line. Interrogator On-line is an index of over 9,500 datasets. It contains information on digital mapping, spatial databases, environmental impact statements, remotely sensed information and aerial photography, held by government and private organisations.
