ABOUT GEODATA AUSTRALIA PTY. LTD.
PROVIDING SKILLS AND TECHNOLOGY IN SURVEY AND GIS CADASTRAL DATA BASE MANAGEMENT FOR GOVERNMENT AND INDUSTRY, THEREBY INCREASING ACCURACY FOR GREATER EFFICIENCIES IN LAND AND INFRASTRUCTURE ADMINISTRATION
Our strategies begin with introducing surveyors to digital survey workflows and the new realm of a survey database, which holds cadastral intelligence allowing automated examination of plan content. This technology facilitates local survey and cadastral database management, but is also scalable to strategic regional and State cadastral systems. The same data structure, GeoCadastre®, in use in many jurisdictions around the world, is Licensed to ESRI and known as 'Parcel Fabric', which Esri utilises in its product ArcGis.
The creation and management of Survey-Accurate Cadastral Models (SACM) assists project planning, engineering design and asset management, which flow to efficiencies for spatially enabled data storage, data retrieval and project decision-making.
GEODATA AUSTRALIA (GA) has considerable experience in historical and modern measurement defining Land Title systems and the application of digital database technology. Importantly, our significant experience generates a pragmatic approach to ensure business and technical solutions remain as simple as possible.
Our approach also recognises that a ‘Fit-For-Purpose’ cadastral solution will be a sustainable beginning for land administration in developing economies, however future security of tenure may require spatial upgrading of that database. GA Strategies can also provide direction and assistance for that, with specialist tools and expertise.

INTO THE FUTURE
Systems Pty. Ltd. (GIS)
GIS was formed in 2000 to promote the development of the cadastral adjustment software, "GeoCadastre®" and the survey software "GeoSurvey™". This software, developed over the last 20 years by Michael Elfick and Michael Fletcher - recognised leaders in the domain of electronic survey database management - creates the core cadastral layer in property-related GIS Systems. Our GeoCadastre® process has now been released worldwide as ‘Parcel Editor’ - the cadastral management engine within ESRI ArcGIS10®.
In addition to marketing and continuing development of GeoCadastre® and GeoSurvey™ software, GA provides interoperability (data migration – LandXML etc), cadastral database and GIS land title management solutions. That interoperability includes consulting services in the implementation of the automated ICSM ePlan lodgement and examination of LandXML survey plan files. GA has assisted the NSW Land and Property Information (LPI) in their successful ePlan implementation and the Northern Territory to implement a minimalistic digital lodgement and examination process outside the rigour of the ICSM LandXML processes.
Our consulting services extend to assisting surveyors and Local Government to implement digital workflows in their survey and cadastral database management. Whilst these software processes have been developed to provide a structure for the most rigorous outcomes in cadastral survey data, they also provide tools to cost-effectively integrate into a functioning land administration system, existing GIS mapping data and the most basic measurement, progressing the integration of both existing survey plan data and modern measurement data.
Incorporation and management of all types of measurement and mapping data, with an understanding of their spatial contribution to a database, are key to efficient land administration and governance systems. GA’s considerable experience in measurement, measurement systems and their application to electronic database technology provides a unique set of skills. Importantly, that experience generates a pragmatic approach to ensure business and technical solutions remain as simple as possible.
Other consulting services and resources include assistance with projects involving the creation and management of Survey Accurate Cadastral Models (SACM) - also sometimes referred to as a cadastral overlay. An accurate cadastral database assists in project planning, engineering design and asset management and then ultimately provides considerable efficiencies for spatially enabled data storage, data retrieval and project decision-making.

WHAT IS A CADASTRE?
A CADASTRE IS A PUBLIC RECORD, SURVEY OR MAP OF THE EXTENT AND OWNERSHIP OF LAND. THE WORD 'CADASTRE' IS DERIVED FROM THE GREEK TERM FOR 'TAX MAP'
Benefits of A Secure And
Legal Cadastral System
Real property (real estate) ownership is the fundamental building block of the modern market economy. Large and small land owners and investors require security of tenure for their property and investments.
The bulk of benefits from a comprehensive, secure and legal cadastral system accrue to local citizens who own, or have rights to land and real estate (e.g. residential, commercial and rural). These benefits take the form of access to cheaper long-term credit, increased productivity, increased land values, stimulated land and real estate markets, more efficient use of land and the opportunity for the creation and accrual of wealth.
Government Guarantee of
The accurate defining of property/cadastral boundaries in modern economies is generally regulated at certain government levels to enable the cadastre to be guaranteed by government. In emerging economies, interest in the establishment of legal cadastres has been fuelled by the need to attract foreign investment, together with the privatisation of public lands and enterprises, to ensure landholders secure the benefits of their physical and commercial endeavours on their land (e.g. farming). The formalisation of usage rights would deliver a similar outcome where private ownership is not an option.
The Australian Torrens Title Cadastral System
The “Torrens Title” system began operating in South Australia in 1863 and has been adopted throughout Australia. It has since been exported to a number of countries and is recognised as a leading cadastral system due to the following:-
Property Boundary definition is undertaken by Registered Surveyors. Title plans registered with the State Land Titles Office must be of a certain standard to be guaranteed by the State Government. The Land Titles Office maintains a single register of all property, ownership and other interests in that land. A Title Deed is issued to the owner and guaranteed by the State Government.
WHAT IS A GIS?
A GEOGRAPHIC INFORMATION SYSTEM (GIS) IS A SYSTEM DESIGNED TO CAPTURE, MANIPULATE, ANALYSE, MANAGE AND STORE ALL TYPES OF SPATIAL OR GEOGRAPHIC DATA ON A COMPUTER, WHICH SYSTEM AND DATA ARE HOSTED USUALLY IN A DIGITAL DATABASE
Accuracy of Spatial Record For Infrastructure
The Cadastre is the fundamental layer in the GIS used by governments, utilities and local authorities. Most infrastructure assets, such as roads, railways, pipelines, power-lines and street furniture are physically located, relative to land boundaries. The accuracy of their spatial record depends upon the accuracy of the land ownership layer.
Improved Database Creation Methodologies
Historically, GIS accuracy was limited by hardware capabilities and the quality of the data entered. Cadastral database layers were input for presentation purposes only, relevant to the way GIS systems were utilised at the time.
Improvement in hardware capability and the rapid development in the accuracy and availability of Global Positioning Systems (GPS) data has highlighted the inadequacy of existing cadastral database creation methodologies, generally digitised and rubber-sheeted to coincide with recognisable ground data features.
The Importance of Spatial Quality
All levels of Government and service utilities now rely heavily on GIS systems for administration, planning, design and asset management. Governments and the private sector now realise that the more spatially accurate land administration databases are, the more valuable they become. In the past the business case was difficult to define, but as reliance on the database content grows, the issues of liability and risk management grow. The issue of spatial quality becomes fundamental. The risks of operational and commercial problems and inefficiencies with a spatially poor database are considerably greater than with a database of high spatial quality.
The Relevance of Database Accuracy
An example of the importance of the spatial integrity of a database becomes relevant when a fibre optic cable running between major cities, containing millions of phone lines and data cables, is incorrectly referenced on a plan forwarded to an operator and, subsequently, is severed during earthworks operations. Millions of dollars per hour in downtime costs are a likely result. An inaccurate database may not have been the cause but an accurate one may have assisted in avoiding the damage and, in any event provides a tighter legal case for apportionment of liability.
