GeoInformation Bremen

from Wikipedia, the free encyclopedia

The GeoInformation Bremen is the State Office for Surveying and Geoinformation of the City of Bremen with the tasks state survey, real estate cadastre, official valuation and land division. It is subordinate to the Senator for Environment, Building and Transport .

History and legal basis

Since 1955, the “Land Registry and Surveying Administration Bremen” of the city of Bremen has had its headquarters in the service building between the Great and Small Weser Bridge. In 1995 the office, which had existed since May 1945, was converted into the business enterprise "Cadastre and Surveying Bremen" .

In 2002 the company Geoinformation Bremen was founded. The basis was the law on GeoInformation Bremen Eigenbetrieb des Landes Bremen (BremGeoG) dated December 4, 2001. The establishment of in-house operations was expected to benefit the state's budget. At the beginning of 2005, the company moved to Lloydstrasse 4 in the Überseestadt district, with the previous five parts of the authorities from different locations being combined.

When the expected benefits for the household could not be realized even after nine years, the in-house operation was transferred to the State Office GeoInformation on January 1, 2011 .

organization

The State Office has four areas of responsibility:

  • Surveying, cadastre
  • Geographic information, spatial reference, topographic-cartographic basic information
  • Appraisal, zoning
  • Information systems

GeoInformation Bremen currently has 150 employees in the office and in the field. 13 measuring vehicles are available to carry out the orders on site.

The surveying and land registry office of the city of Bremerhaven is independent and subordinate to the local magistrate.

Land survey

The state survey provides the basic data for all spatial information systems in the state of Bremen. Throughout Bremen, fixed point fields are provided in the respective geodetic reference systems for the position, height and gravity.

GeoInformation operates a network for the following fixed points:

  • The points of the location control point field form the geodetic basis for property surveys, for topographical national maps and for technical and scientific purposes.
  • The height control point field is spread over the entire municipality of Bremen. The points form the basis for building measures, disaster control, canal cadastre and terrain models, among other things.
  • Fixed gravity points (SFP) are measured using suitable leveling points (NivP) or trigonometric points (TP) and gravimeters. This means that the acceleration due to gravity can be determined with the greatest possible accuracy. The SFP located in the state of Bremen are co-administered by the state surveying and geographic base information Lower Saxony (LGN).

GeoInformation Bremen operates infrastructural facilities for the satellite positioning service of the German land survey (SAPOS) . The system is based on a network of GPS reference stations. It establishes the technical connection to the future official spatial reference system ETRS89 .

cartography

GeoInformation Bremen creates the official topographic map (TK 50) for Bremen and Bremerhaven .

3D model of the city of Bremen

On behalf of the Senator for Environment, Building and Transport and the Senator for Economy, Labor and Ports , GeoInformation Bremen is to develop a virtual 3D city model of the city of Bremen. This model has already been implemented for some areas.

The city model contains building models with a connection to basic data (property map). The digital 3D city model is based on a geo-referenced database system. The model can be output in the usual formats for 3D models. The basic model sees itself as a universal basic database for applications in the technical as well as in the design and planning as well as representative area. Based on the requirements of the respective user, the basic model is expanded to include B. terrain models, engineering structures, textures, soil structures, map bases, vegetation elements, planned objects or objects under construction.

The following applications are currently possible or available at short notice: the calculation of sound and immission propagation, an overview of suitable areas for solar thermal and photovoltaics and online presentations.
