Stuttgart opts for AED-SICAD to implement ALKIS+
Integrative solution for real estate cadastre and communal data
After the public invitation to tender for its ALKIS+ (Authoritative Real Estate Information System) solution, on July 25, 2005, the German provincial capital Stuttgart, opted for the offer of prime contractor AED-SICAD and its partners BARAL, ARC-BERLIN and ESRI Geoinformatik. Like this, the components of the ArcGIS®-based 3A product line for data management, collection, qualification and migration are going to be used in the future. Stuttgart explains the decision with the fact that the AED-SICAD solution fulfils all technical requirements and at the same time offers the highest profitability.
Stuttgart is the first large city in Baden-Württemberg that enters into the ALKIS® realization phase. Apart from the base data of the real estate cadastre, also additional data are integrated, for example communal land parcel or building data, the hunting cadastre and others (ALKIS+). Here, AED-SICAD benefits from its vast experiences in both areas – Land Management and Communal GIS. Thus, the municipal cadastre agency, which is responsible for the provision of geodata, creates an integrated system with uniform ALKIS compliant database and data processing.
Stuttgart is using the data management component 3A Server as well as 3A Editor for data collection, qualification and update. In addition, AED-SICAD also provides standardized migration tools with 3A Migration, which are configured according to the requirements of the German Federal State Baden-Württemberg by its partner BARAL. The project also includes the automated creation of ALKIS compliant presentation output from the database component as well as the use of the product 3A Survey of partner company ARC-BERLIN as field survey solution. The data, which were migrated and processed in the new system, are then distributed in the Intranet of the municipality via the already existing information systems, like e.g. GEOLiNE, which is also based on ESRI’s ArcGIS technology.
Bernd Hornung, project leader ALKIS+, municipal cadastre agency Stuttgart:
“Our aim is to create an integrated system for the management of geobase data and the branch data of the municipal cadastre agency – with clearly defined components. Our GIS strategy builds on national and international standards, object structured data and a user environment that can be flexibly extended. AED-SICAD’s 3A solution, based on the leading ArcGIS technology fully meets these requirements and is going to replace our former IBM-GTIS system.”
As the first large city in Baden-Württemberg, Stuttgart begins with the realization of ALKIS on communal level, therefore having the largest amounts of data. These are going to be logically integrated in a 3A Server, based on an Oracle database. The city’s ALKIS activities are offering a long-term perspective and serve as example for other municipal surveying agencies in Baden-Württemberg.
According to project manager Hornung “ALKIS+ is not only the municipal basemap but far more than that. By bridging geobase data and various communal branch data we increase the profitability of the geoinformation by far. With ALKIS+ we are entering new territories between surveying tasks and – based on these – complex application fields within a community. In both areas, we are profiting of the excellent branch know-how of AED-SICAD and its partners.”
Among the application fields of the data provided by the municipal surveying agency are – among others – the characteristic areas like city planning and renovation, environment, real estate, business development as well as the Civil Engineering Office and the independent company for sewage. However, also the department for statistics, the social and youth welfare office, which is visualizing its assets on the basemap, as well as the office for law and order, saving numerous on-site appointments, makes use of the geoinformation. Already today, around 1.500 users from nearly all parts of the city administration work with the information, which up to now had been provided in the Intranet. With the decision for AED-SICAD, Stuttgart has a flexible solution and is able to integrate further objects or advanced topics, and make it available for the users via the viewing system GEOLiNE.
