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
– [email protected]
Dissemination Databases and the SDI
Dissemination database access to spatial data
Client Applications
NT Visualiser
Oracle Clients
(Google Earth Enterprise)
- MapInfo, FME, SQL / JSP
Spatial Data Download
WMS Clients
(ILISMaps or scheduled download)
- ArcGIS, MapInfo, Web Apps
Web Services
ILISMaps/NT Atlas
Automated Mapping
RenderX (XEP)
- generates PDF from SVG
Users
FME
- generates SVG from spatial data
- for customosed inquiry services

Example: Aerial Photography Index

Data comes in as CSVs from flight contractors
– includes: photo centre point, scale, bearing
– obliques

FME appends latest data to 4 existing oracle tables:
– frame centres, frame coverages, run lines, project coverages



Data – driven client applications:
– Aerial Photography Index
– Google extractor
Rapid turnaround / publish timeframe
‘Codifies’ data load procedure
Example 2: Building Asset Management System


BAMS ‘spatialisation’: currently in development
Data maintained in AutoCAD DWG files
– Greater than 20 levels / feature types
– periodic simplification using LISP routines down to 4 levels
– FME workbench run by the data custodian

FME builds 4 dissemination database tables:
– primary assets, building & roof outlines, ground floor details


Extract to ILISMaps & Google Earth Enterprise
FME captures the conversion procedure

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

Increasing use of FME for dissemination database establishment
use in gaining buy-in to produce KML as interim to Oracle
Automated Mapping: MapText
– move from manually placed, scale based text
– migration to Linux
Spatial Data Download: Online Broker
– public access
