Digital cadastral data
The Digital Cadastral Database (DCDB) is essentially a computerised map of property boundaries and the related property description of all land parcels in Queensland. It is an ideal base for searching, planning and analysing land related information and is used by most local governments for these purposes.

Reliability
The DCDB is continually being improved using information from:
- survey control data and survey plans
- registered plans of subdivisions
- government gazettes and administrative notifications
- upgraded data and survey control network received from local authorities.
Strata, easements and boundaries of administrative areas have also been added.
Data attributes
Data in the DCDB consists of:
- a spatial component including
- land parcel boundaries
- coordinates of land parcel corners
- natural features (e.g. creeks) which form part of a property boundary
- an attribute component including
- lot on plan number
- area
- road and street names
- river and creek names
- feature names
- locality names
- alphabetic codes for tenure
- numeric codes for local government, parish and locality.
For further information on the above topics, see the Queensland Interchange Format Specifications (QIF) (PDF, 323K)*. Customers receive a metadata file when digital cadastral data is supplied.
Geodetic datum
The geodetic datum for the DCDB is GDA94. Data can be supplied in:
- grid coordinates (Eastings and Northings)
- metres
- geographical coordinates (latitude and longitude) in decimal degrees.
Data format
Data is extracted from the DCDB in the Queensland Interchange Format (QIF) (PDF, 323K)*.
It can be translated and supplied in proprietary GIS formats (ArcInfo, ArcView, MapInfo or MicroStation) depending on the product selected.
A QIF2MapInfo translator is also available for purchase.
