The West Australian Land Information System or WALIS is a dynamic partnership of State Government agencies, of which Main Roads is a member, working with local government, business, education and the community to manage the state's land and geographic information. WALIS is a complex system with diverse stakeholders and customers. The success of WALIS depends of a high level of collaboration and cooperation by these participants.
There are significant benefits to be gained by sharing land information. By using WALIS, costly duplication of data and systems, as well as the use of inconsistent information, are avoided. Sharing land information, building a consistent view and bringing land information to the user is the essence of WALIS.
WALIS is not a single centralised database, but is being developed as a network of systems and databases to provide users with access to data held by all WALIS participants.
Main Roads is represented on a number of WALIS technical committees and the WALIS Council to ensure that the interests of Main Roads are addressed when the WALIS community develop systems, policies and guidelines with respect to Land Information.
The WALIS Council focuses on operational co-ordination and information exchange. It allows Main Roads representatives to ensure key strategic and operational goals are met in regards to land information and spatial initiatives. It also allows representatives to share key initiatives in their respective agencies to identify possible collaborative efforts and reduce the costly duplication of data and systems.Main Roads is currently represented on the WALIS Council and technical committees by the following positions:
A major policy instigated by WALIS (through agencies) and ratified by the Executive Policy Committee (EPC) is the ability of government consultants/contractors to obtain government information at government rates. Currently government agencies obtain information at a discount rate of 10% of actual cost whereas all private industry pays the full 100%.
Refer to the guidelines on Data Purchase or Supply for further information.
In summary this means that there is two ways for a contractor working on a Main Roads contract to obtain external information (eg; Cadastral, Geodetic, Photogrammetric information from other agencies). The two ways are to either to obtain the information through Main Roads direct or request the information directly from a particular agency.
To do the latter, a letter authorising the contractor to obtain the information is required from the Project Manager as well as a signed license agreement. This is then forwarded to the respective agency. It is important to note however that agencies have set formats that data can be supplied in. If the format is not compatible and the contractor is obtaining the data direct then it is his responsibility to ensure the compatibility of the supplied data with his systems.
The Data Manager - Survey and Geospatial Services can provide advice on specific data issues.
The WALIS Community are currently involved in a number of cross government projects.
The following government agencies and private organisations are members of WALIS.
