6 Official Surveying and Mapping in Germany Official surveying and mapping belongs to the responsibilities of the 16 states, t not to the federal level State Survey and Real Estate Cadastre in one authority, but different organisational structures t The private sector - publicly appointed surveyors - is involved in cadastral surveys in 15 states

7 Official Surveying and Mapping in Germany The administrations i ti belong to different ministries: Interior (8) Finance (1) Economy, Traffic (1) Land Development, Traffic (1) Environment (1) Rural Affairs (1) Ub Urban Development t(in the 3 city states)

8 Federal Republic of Germany 16 states ( Länder ) AdV an umbrella organisation on voluntary basis German Geodetic Commission

9 Tasks and Responsibilities of AdV Recommendations, guidelines and binding regulations for state survey and real estate cadastre in Germany All decisions of AdV are recommendations and have to be transposed into state laws Co-ordination of state overlapping projects Co-operation in research, development and application of technical methods and procedures Representation of official surveying and mapping of the states of Germany in international organisations and co-operation at international level

10 Private Sector publicly appointed (1) Publicly appointed surveyors in 15 states (exception Bavaria). The institution of a publicly appointed surveyor is regulated by state laws. Some figures: Number of licensed surveyors: DE ca / NRW: ca. 450 Number of staff : ca The license is given by the government of a federal state t to an individual, not to a company.

11 Private Sector publicly appointed (2) The license is valid only for that one state (comparable with the regulations for civil servants). Although the publicly appointed surveyor is a freelancer, he/she is part of the official surveying and mapping of that state. Mostly he/she is working in the field of cadastral surveys. The publicly appointed surveyor is concerning to the public appointment acting on behalf of that state and uses the seal of the state for the functions publicly appointed.

12 Private Sector publicly appointed (3) The activities of a publicly appointed surveyor are subject of special conditions and regulations (e.g. concerning liability and insurance, withdrawal of the license, advertisement). The publicly appointed surveyor has the same education as comparable civil servants (4-5 years university plus 2 years of additional traineeship with state examination). The publicly appointed surveyor is supervised by the state not by a chamber. Same scale of fees as the public sector to avoid unfair competition.

13 Real Estate Multi Purpose Cadastre German Constitution (Grundgesetz): Article 14 [Property, inheritance, expropriation] (1) Property and the right of inheritance shall be guaranteed. Their content and limits shall be defined by the laws. (2) Property entails obligations. Its use shall also serve the public good. (3) Expropriation shall only be permissible for the public good. Task of the property cadastre: official parcel register for the land register register for the results of the official rural ground value determination base for property valuation and taxation strong role in the real estate transaction process 100 % digitised (cadastral data base)
