Northern Territory Land Information System
A cooperative arrangement between NT Government agencies, other
governments and the private sector, designed to deliver better outcomes for
government, the community and industry from the use of spatial data
resources
Focused on sustainable spatial information management
Build and maintain spatial infrastructure
Consult to government agencies
– application design
– data storage methods
Coordinate training, licensing and support

NTLIS Metadata Tool





ANZLIC profile of the ISO standard
– (Hopefully) compatible with GIS software of the future
Web based, free to use by government and non government custodians
Data dictionary
Metadata forms a spatial dataset itself !

NTLIS Spatial Data Broker: Development


Currently in development
– aiming for 4th quarter 2007 release
Allows non-government users access to
the existing ILIS Maps Spatial Data
Download
–


vector data only
Users must have pre-arranged data
license agreement (and payment) for
restricted datasets
Custodians must have satisfied the Spatial
Data Accessibility checklist for datasets
(see Forum)
NTLIS Spatial Data Broker: Development


Data must be in a dissemination database
Custodians control access
–
–

End users control output:
–



format, projection, extent
ANZLIC / ISO 19139 metadata inclusion
Logging of who downloads what
Data license awareness
–

role based authentication: ILIS
layers, attributes, polygon extent
renewal reminders
Auto downloader
–
–
allows users to schedule downloads
used by NTLIS web applications
NTLIS Spatial Data Broker: Architecture
End users
Spatial Data Broker
Administer
Custodian 2
(Oracle Application Express)
Layers Permission Administrator
- custodian defines:
- permissions for each of their own layers
- Metadata URL
- Shapefile (short) attribute substitutions
- Extent polygon
Download Form
- detects user role and current license
agreement and presents list of
available layers
Data License Administrator
- custodian manages existing data licenses
- schedule renewal reminders
- view existing license
Spatial Direct
- choices for format & projection
- only accepts connections from Spatial Data Broker
