The Development of the Austrian Cadastre from Documentation to an Integrated Planning

and Decision Support System

Wernher Hoffmann

Real estate infrastructure, fit for use?

Land register, fit for use?

Cadastre, fit for use?

But what means “fit for use?”

Austrian Cadastre, fit for use?

Clients want……

• … a fast process of property building

• … legal certainty

• … traceability

• … orientation, documentation and information

• … accessibility and availability of information

• … information up to date and even from the past

• … all the information wherever they are

• … all the information whenever they want

• … integrable and machine-readable data

• … additional information digital available

• …



Customer requirements developed over time

• Land administration systems have a strong impact on

legislation of other administrative tasks.

• A strong interaction between system design and

customer requirements exist.

• Understanding legal and system constraints is absolutely

necessary, because in land administration history is

nearly unchangeable.

• Therefore understanding the history is knowing, what

was the main purpose.



Main purposes were added over timePurpose of taxation: “Property Tax Cadastre”

since 1817…

since 1873 cadastre and land register in “accordance”

Purpose of legal certainty: “legal cadastre”

since 1969 surveyed boundaries are legally binding

Purpose of automation

since 1980 Real Property Register (no boundary information)

since 1987 Digital Cadastral Map (boundary information)

Purpose of information

since 2003 Dissemination System eGeodata Austria

Purpose of integration

since 2010 product web services

since 2012 integrated Process between Cadastre and Land Reg.



Cadastre: from Documentation … 1817 -

• The Cadastre documented primarily the relative position of parcels to another

• Therefore the cadastral map was a picture with very little legal relevance

• The main purpose of cadastre was taxation. Therefore the updating of the Cadastre had a low priority and was carried out only once a year.

• The archive of documents was more important, but in doubt the situation in nature was more valid then the deeds.

• Every Cadastral Unit has a cadastral map (Island maps)



… to a reference documentation system…

• Development of a system of rectangular map sheets all over the country

• Gauß-Krüger projection was the mathematical basis

• With the scale 1:1000 the cadastral map was the most detailed reference information

• Cadastral information was public and therefore available for other documentation purposes

• Geoinformation recorded for other purposes for example infrastructure building, Rural Development, Regional Planning, etc. was documented on copies of the cadastral map

• Million of blueprints of the cadastral maps were made each year and were then updated with the additional information

….to an information system …• Digitization of the cadastral map• Public authorities and

infrastructure companies started using the Digital Cadastral Map as an information system

• therefore changed the requirements of CAD to GIS

• the correct topology of the data was a big challenge

• topological structures enabled the intersection and integration with other data (e.g. Real estate database, zoning, ...)

• problem: Distribution and up-to-date-ness of data



… integrated Planning and Decision Support System

Requirements:

• Fast and reliable maintenance of date (no gaps)

• Traceability (Process documentation and historicization)

• The legal relevant information of the surveying deeds must be the same in the digital cadastral map

• Online availability

• Web services for online integration in customer systems

• Individual data requests on single objects and entities
