Business Problems – con’tFile based datasets – single editNo audit trailIncoming info did not work well with GIS

As ConstructedContractsDay labour

Realised the difference between “Data Capture” and “GIS” – they overlap, but not the same

Need “Right tools for the job”


Business NeedFeb 2004 –

To implement a water/wastewater specific system that would enable seamless concurrent asset capture between GIS and OASIS (Hansen) while maintaining the data integrity inherent in the OASIS system.

Strategic alignmentCity Assets – “Develop and maintain appropriate information systems to support informed asset related decision making”


The Project

Descriptively named –“Data Capture Improvement Project”Gold Coast Water only

Minimal impact on Corporate GIS environment

Urgency due to asset capture backlog


General Requirements

Water and Wastewater SpecificOff the shelf functionalityCustomisable where required

Manual drawing functions – CAD like toolsSeamless integration with Hansen

User to have no direct interaction with HansenCode / Lookup tables – single source

Oracle Spatial Database based


General Requirements – con’t

Migration of MapInfo datasets to OracleOpen access/standards

Future proofed solution

Compatible with current GCCC GISSystem only for asset capture and analysis, other GIS users would still maintain current access

Ability to receive data from multiple sources eg. dxf, SEQROC (GML)

Selection

Invited GIS vendors with existing Hansen Integration tools (select tender)The selection process identified that the industry has acknowledged there is a need for this type of system and we were impressed at the level of fit of all the responses


The Solution

Oracle Spatial data storageOpen GIS standardsMigration of GCW GIS data to Oracle Spatial“Munsys” Data CaptureUtilise and enhance existing Munsys –Hansen integration tool


The Solution – con’t

Hansen IntegrationAccepted by HansenUses Hansen API and direct access to databaseHansen is point of truth for codes/lookups, Administrator maintains from Hansen end and Munsys is updatedNo user interaction required with Hansen app

Implementation Issues

Clean data is not clean dataIntegration challenges when dealing with multiple vendorsChange management of staff from “old school” file based systemsStaff skill sets had to be upgraded for this project


Current State of project

Asset capture went “live” in April 2005Hansen tool is working well, however some additional features missed in our initial technical spec are being addedMapInfo (corporate GIS) integration in place – not yet automated


Summary

Impressed with what we can now do with our data

Usability of the data separately as spatial and aspatial as well as combined

Data is now secure and futureproofIntegrated reporting possible with HansenReady for MIDAS deploymentLot more cleansing to doGIS team excelled in the implementation


Summary – con’t

Productivity GainsEven with problems in the source data format, capture is nearly twice as efficient.Huge benefits expected once GCCC adopts a more appropriate digital data lodgement standard – will be able to map lodged data directly into Oracle Spatial through the Munsys application (to ensure integrity).No more manual asset capture into HansenAble to use most appropriate tool on the single data source.
