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
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. 1.500 / NRW: ca. 450 Number of staff : ca. 15.000 The license is given by the government of a federal state t to an individual, not to a company.
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.
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.
