NTLIS is responsible for maintaining various online services including ILIS and the NT spatial data infrastructure, and promotes the 'dissemination database' model for storing and delivering spatial data in the NT. The model recommends that data be made available by publishing it to a single reliable and accessible location, typically Oracle Spatial. From there applications and users can be guaranteed to be using up to date data, consistent with its metadata documentation. This model is described in the diagram below, where a range of applications and users are able to see the data stored in the dissemination databases, to a level agreed upon by the data custodians.
