- initial situation -
Deficiencies of the process solutions ALB and ALK
 the concepts of ALB and ALK are obsolete
 large data redundancy in ALB and ALK
 no consistently object structured data model
 no uniform data structure
 different data interfaces (EDBS, BGRUND, WLDGE, ASCII, …)
 no standard scheme language
 no concepts to describe metadata and data quality

- objectives -
to get away from redundant data management in ALB and ALK
to get away from different data models
to get away from many different data interface formats
move towards more uniformity in Real Estate Cadastre

- new cadastre standard -
ALKIS – a new cadastre standard
 uniform object-structured data model
(instead of the previous parcel centered view in ALB)
 integrated management of graphic and semantic data in ALKIS in
attendance with harmonizing the content of ALKIS and ATKIS
(object-structured AAA-model)
 international standards (ISO, OGC) > interoperability
 standardized exchange interface (NAS)
 standardized description language (UML)
 management of metadata and data quality

ALKIS – Components
 Component for data collection and
qualifying (EQK)
 Component for data storage (DHK);
nationwide and daily updated data
 Component for information and
presentation (APK); database for
producing ALKIS standard outputs (e. g.
land parcel proof and real estate map)
described in the Documentation on the Modelling of Geoinformation
of Official Surveying and Mapping (GID reference version 6)
