Organisational Context Manage natural resource investment Develop and manage natural resource

datasets Use these spatial datasets for Planning,

Reporting, Monitoring and Evaluation Currently maintain these important datasets

- Land Use- Salinity Outbreaks- Groundwater Bores- Soil profiles and Soil Landscapes- Land Capability

5

Examples of Natural Resource Investment

Establishment of localised native vegetation Riparian bed stabilisation and bank protection

works Fencing off areas of significant vegetation Location of troughs and tanks for water

supply infrastructure Removal and control of noxious weeds Trapping and control of feral animals

The Land Management Database

Primary user is the NSW Catchment Management Authority’s

A customisation of ArcMap Provides a consistent standardised

process Features compiled automatically on a

centralised database. Provides instant reporting (using Crystal

Reports) against a range of criteria Links to other natural resource datasets

18

Background Developed over six (6) years The organisation had a significant Arcview

3.3 user base. Recently implemented Oracle spatials and

was beginning to use ArcGIS 8.1 New to ArcObjects development and how

it interacts with our new spatial infrastructure

19

Background - continued Many workshops and data modelling

sessions. Discussions with our DBA’s who were

implementing our Oracle Spatial systems. Preliminary programming was undertaken

in 2003 however the project stalled in 2004 when Amanda left the organisation.

In 2005 further development occurred and it was implemented on ArcGIS 9.0

20

Implementation The programming to export to the Central

database was completed in 2005. Went through our change control

procedure to the production database. We could now easily demonstrate the

benefits of a centralised database for corporate reporting.

Began marketing the LMD to the CMAs and within our organisation.

21

Development Environment

Microsoft Visual Basic 6. Active-X dynamic link library (dll). ESRI ArcObjects libraries. Microsoft Jet Engine libraries High speed Wide Area network

22

EDB

Users operate independently and store data centrally

23

Database Environment Modelled and designed using Visio. Front-end and back-end solution “one-to-many-to-many” relational model. Points, lines or areas stored locally Centralised (EDB) database uses

Oracle spatial 10 with SDE 9.X elements.

24

Database Key Management

Database are checked out with each LMD database

Keys are unique across the WAN

Upload of spatial data using Append function

Spatial integrity maintained locally

25

LMD Feature Classes on EDB

26

Spatial Feature Description Rels

One unique number (LMID) per spatial feature

To many sub-

typesTo many activities

27

28

Application Updates

The system Automatically updates itself across the WAN from the EDB.

One xml file on EDB controls the system versioning and updating functions.

All LMD Geodatabases link to lookup tables stored in an external reference database, no domains.

Allows easy update and management of the reference data for description or attribute list.

Features of the LMD Tool

Standardised attribution list (1859) Customisation for all users, limit available

attributions. Detailed attribution of area, line and point

spatial features Up-load of attributed feature data Instant reporting once data up-loaded
