Coordinate reference system– Gauß- Krüger
projection (Transversal Mercator)
– 3- degree- stripes for Austrian territory
– cm- accuracy of coordinates

Data structure of the DKM
• (partly) according to the AutoCAD- Software– DXF- format is broadly used also outside BEV
• Structured in logical layers• Graphical elements
– POLYLINE– CIRCLE– BLOCK REFERENCE (INSERT)– TEXT
21.Novembre 2011 Standards and Data Model of the Cadastre in Austria Page 12
Basic elements of the DKM
• Points, lines, symbols, text, attributes• Square elements:
– Parcels, land cover
• Block information: – Combination of symbols and attributes– e.g. Border point: symbol, point number, attribute
(indicator, )
• Connection to central database:– number of administrative unit, point number,..
21.Novembre 2011 Standards and Data Model of the Cadastre in Austria Page 13
Data structure of the DKM
• Defined objects– Map Sheet– administrative borders and borders of parcel (state
border, province,... administrative unit, borders of parcel )
– Parcel number– Land cover (lines, symbol,..)– Buildings– Other lines, symbols,..– Border-, state border -, control points

Process to store DKM _1
1. Maintaining and checking of the DKM– BEV-DKM-Application: AutoCAD– “local” check of the DKM: nodes- lines- structure,..– Automatic check of map sheets: Points, coordinates,
cadastral units, etc.
2. Checking and reload of DKM in Shape-Format– Check of all objects, indicators, cadastral unit,..– Report of all errors (“K-files”) > improve data– Generate shape- files
21.Novembre 2011 Standards and Data Model of the Cadastre in Austria Page 21
Process to store DKM _2
3. Central storage of DKM– DXF- Files (only for internal process) and Shape-
files– Update of central Real Estate Data Base – Real Estate Database and database for e- geodata
Austria (access to all data of BEV via internet)

Conclusion, outlook
• Ongoing change of the data model for New Real Estate Database
• Joint project between BEV and MoJ to develop a new integrated system– Fully “digital” processes between Cadastre (cadastral
offices) and Land Registry (local courts)
• Using open standards (OGC) Optimize internal processes– Standardizing of the system– Design of new processes for Cadastre and Land Registry
