Types of spatial data

QSpatial includes data from participating Queensland Government agencies and displays metadata about downloadable data, either extracted on the fly or pre-packaged, available web map services, as well as information about offline resources.

Searching this repository you can discover, select and download spatial data over an area of interest. The data you download can be in a selected format which is specified by the publisher and advertised in the metadata: GDb, Shp, TAB, KMZ, map coverage data, image data and text file data as well as web services (APIs), or a pre-packaged format (DP).

Viewing spatial data

To view the spatial data downloaded from QSpatial you will need access to Geographic Information System (GIS) software. If you don't have access to GIS software, you don’t need to download the data, simply view most all of the data in the Queensland Globe.

How do I know when the data is updated in a dataset

Data alerts are available if you are logged in. They are under User Profile - Saved Subscriptions. When a subscribed dataset is updated by the data publisher, a notification is sent out the following day (6am) via email. Data available as a web service is ‘live’.

How do I find the accuracy of data

In the metadata you will find under Data Quality the Positional accuracy and Attribute accuracy statements. You can also determine accuracy by reviewing the History > lineage statement but this field is not mandatory.

What is the accuracy of the Digital Cadastral data set

The point of truth for property boundaries is the survey plan. The digital cadastral data set is a graphical representation of these boundaries. You can purchase a copy of a survey plan through the Titles Qld online title and image searches page.

The digital cadastre was originally captured by digitising the department’s cadastral maps. Positional accuracy was derived from the source map scale and the precision of the digitising. This positional accuracy initially varied throughout Queensland from +/-1 metre to +/-250 metres. This has been gradually improved so that the worst positional accuracy in Qld is currently +/-63 metres. More information is available via our page: Accuracy of the digital cadastral database.

Details about accuracies and other attributes can also be found in the Queensland Digital Cadastral Database data dictionary (QIF).
