One example of openly accessible public sector information that exists within state government is the Shared Land Information Platform (SLIP), a Western Australian cross-government initiative spearheaded by Landgate, the state’s authority on land information. SLIP brings together spatial datasets from approximately twenty agencies (mostly at state level, but also some from local and federal level), and disseminates them online through WMS and WFS services. I should point out here that each agency retains FULL custodianship of their own data; SLIP provides the means to publish that data online from a single point.
Landgate has a significant amount of information which is freely available, including WMS products through our map viewer, WA Atlas (https://www2.landgate.wa.gov.au/waatlas/). Other data, including cadastral, topographic and imagery data is also available to all, at a cost. Landgate is presently considering Creative Commons licensing as part of the National Government Information Licensing Framework Project.
While there are a diverse range of datasets available through SLIP (the full list can be found at https://www2.landgate.wa.gov.au/slip/portal/services/datasets-available.html) I note there is some overlap between what has already been suggested and what Landgate could contribute:
-Administrative boundaries: Suburbs, localities, Local Government Authorities and even individual council wards
-Land title information: Cadastral information
-Road and railway line data
-Topographic data, particularly spot heights, contours and points of interest
-Community facilities such as Public Access Ways and building footprints
-Native title data
-Aerial photography and imagery
SLIP data can be accessed in a variety of ways, including the aforementioned WA Atlas, or using any of the GIS applications available. We have a number of guides available on how to access this data at https://www2.landgate.wa.gov.au/slip/portal/services/access-slip.html, and through our useful links at https://www2.landgate.wa.gov.au/slip/portal/links/links.html.
