Spatial Data Maintenance Applications

Digital Cadastral Database (DCDB) and Fabric Manager

The DCDB is the authoritive source of Surveyed Cadastral information in the Northern Territory. Fabric Manager is a custom-built plugin for Micro Station written in MDL and C to manage the business rules and data manipulation of information in the DCDB.


Spicad manages cadastral survey co-ordinates, survey geometry and parcel details. Spicad data is maintained in two separate database instances, one in Darwin and the second in Alice Springs.

Metadata Tool

The Metadata Tool stores metadata about the spatial layers that are offered by various departments of the Northern Territory government. This data allows custodians of spatial data to publish the fact that they have spatial data on a given topic available as well as defining the attributes that are on the spatial layer. This tool has a maintenance side as well as allowing the public to search for what layers are available.

Base Stations

The Base Stations application stores details about GPS base stations around Australia. The base stations are used to correct GPS accuracy. Both spatial and textual data is stored in relation to each station. Since spatial data is stored we are able to create a spatial layer which can be used in map generation to show all the stations within a given area.

Soil and Landform Information (SALI)

SALI is an internal government application used by NRETAS to store their soil analysis data. This system is currently under development and testing.

Heritage Register

Heritage Register in an internal government application used by the Department of Natural Resources, Environment, The Arts and Sport (NRETAS) to store details of heritage-listed sites throughout the Northern Territory. The register stores textual and spatial data about heritage sites. This data is then fed back to ILIS for use in Land Searches to inform users a parcel is heritage registered.

Map Products Display System (MPDS)

MPDS is an internal government application used by NRETAS to store details on the maps they have generated for public use. This system is currently under development and testing.


Relational Data Systems has created a user-friendly system for Minerals and Energy that increases the reporting and charting capabilities of their previous database, which is used to store analytical data such as concentration of chemicals, pH and electrical conductivity in water samples from mine sites. Relational Data Systems has developed a new application similar to the existing system but with the following additional benefits:

  • accommodates the use of additional environmental data such as biological, meteorological and hydrological data
  • profiling of chemical data over water depth
  • improved data import facility to make the process less cumbersome
  • more powerful graphing capacity to accommodate high data throughput
  • rapid changes in variables in a multi user environment.

The new system now also integrates mining data with spatial information and possesses a simplified data importing facility and graphing capacity to accommodate reporting requirements, including dynamic graphing and a more powerful ad-hoc reporting facility.
