Data Integration

Inquiries for data integration in geodata servers or geodata warehouses are rapidly arising. The distinctive challenge is, that different and possibly very complex heterogeneous datasets have to be collected, integrated, stored and updated in a homogeneous repository which can be accessed by open IT-standards independent from any GIS-technologies. In addition, catalogues for data description (metadata) have to be managed.

Within the warehouse the data can  not be merely selected according to aspects of original content, i.e. certain features classes from source x and other layers from source y, but one important benefit is, that they can  be combined and modelled in the manner that they result in a new information.

Today, geodata servers or warehouses are recommended to be used from different organizations and their subsidiaries: for example, large government departments and utilities do not longer inevitably depend on using one particular GIS centrally Instead the system decision can be made related to the requirements of all different users within the organization. By such a concept they can choose the best suited solution for their purposes. In this context it is important to note that the concept of a geodata server/geodata warehouse can be introduced step by step and is independent of a specific GIS. Appropriate geodatabase - software, which allows a GIS-independent administration of the data, is already on the market.
