GEODATA INFORMATION SYSTEMS P/L (GEODATA) is a Company formed in 2000 by a group of Hunter Valley Land Professionals to promote the development of the Cadastral Adjustment (GeoCadastre) and Survey (GeoSurvey) software developed over the last 20 years by Michael Elfick & Michael Fletcher for a user group of Survey Companies throughout Australia. The software is now patented worldwide.

GEODATA promoted the software to the ENVIRONMENTAL SYSTEMS RESEARCH INSTITUTE Inc (ESRI) at Redlands, California, which is the world's leading GIS Software Company. ESRI focuses on large scale government mapping and database management and is in use in over 200 countries. ESRI's decision to use the GeoCadastre methodology was made after reviewing many cadastral solutions from around the world to confirm that the software process and workflows provide the most effective model, and management system of a legal cadastre for use in GIS systems.

Geodata has sold exclusive world-wide rights to use the 'GeoCadastre' process within a GIS software package to ESRI for their cadastral management. Geodata has retained the rights to market the GeoCadastre software as a fully supported stand-alone product with full interoperability (being able to read and output to other data formats).

THE ESRI - GEODATA ALLIANCE


GEODATA AUSTRALIA P/L (GA) is a survey & cadastral database consultancy, providing specialist software development and implementation skills and tools to government and the private sector. GA is a consulting subsidiary of Geodata Information Systems P/L (GEODATA) which was a Company formed to promote the development of the Cadastral Adjustment (GeoCadastre) and Survey (GeoSurvey) software developed over the last 20 years by Michael Elfick & Michael Fletcher for a user group of Survey Companies throughout Australia. The software is now patented worldwide.

GEODATA promoted the software to the ENVIRONMENTAL SYSTEMS RESEARCH INSTITUTE Inc (ESRI) at Redlands, California, which is the world's leading GIS Software Company. ESRI focuses on large scale government mapping and database management and is in use in over 200 countries. ESRI's decision to use the GeoCadastre methodology was made after reviewing many cadastral solutions from around the world to confirm that the software process and workflows provide the most effective model, and management system of a legal cadastre for use in GIS systems.

Geodata has sold a world-wide license to ESRI to use the 'GeoCadastre' process as the ESRI ArcGIS cadastral management engine. GA has retained the rights to market the GeoCadastre software as a fully supported stand-alone product with full interoperability (being able to read and output to other data formats).

The need was outlined to ESRI to design and deliver an architecture which created or migrated a parcel network fabric into the GIS database and then allowed an adjustment and update of both survey points and features within the GIS while retaining the original survey Title data. The result for ESRI was a completely new data model for parcels built within a GIS database.

This process took several years of joint product development as ESRI had to incorporate cadastral storage in the geodatabase as defined by points and lines (survey methodology) rather than shape files (GIS/mapping methodology). The need to retain the original Title dimensions to describe any legal parcel rather than the dimensions from the adjusted cadastral model was also a move away from traditional GIS methodologies.

THE GEODATA AUSTRALIA VISION


The GA focus is now on the implementation of the technology within and outside the ESRI database environment and the provision of cadastral database management services utilising our experienced team of Land Professionals.

Notable projects utilising GA technology and services include:

  • The Northern Territory where title coordination legislation enacted was enacted in 2004.The legislation requires the spatial quality of the cadastral model to be ratified in a particular area for title coordination to occur. We have also built higher level database and web enabling tools to assist them in implementation of the coordinated title system and provide remote web access to the administration database.
  • The NSW LPMA ePlan Pilot Project which will provide considerable efficiencies through electronic lodgement and automatic examination of survey plan LandXML files. The examination process updates the database and could allow the Titles Office to immediately update and make available the state cadastral database to all stakeholders.

These projects were achieved through the utilisation of the GA Survey Data Model process.

The project team delivering these outcomes includes:
Roger Lee - Managing Director - 30yrs experience in Valuation & Land Administration in Australia and S.E Asia
Michael Elfick - Registered Surveyor - 40 yrs experience in surveying & survey software development
Ian Harper - Surveyor - 25 yrs experience in consulting cadastral surveying & land development.
Sharmane Jackson - GIS Manager - 4 yrs experience in cadastral mapping.

The GA technology and experience provides a database outcome from survey processes to generate management and business efficiencies in land administration databases through cadastral accuracy.


By understanding the basic components of measurement and database technologies, we specialise in incorporating all existing measurement and database formats and workflows into the Survey data Model process to move forward.
