Traditionally, GIS users have depended upon files (usually ESRI's shape file or computer aided drafting files such as DGN/DWG) to store geographic information. Despite their ease-of-use, file-based GIS data storage methods do not provide the performance, security, and availability necessary for a GIS to support an enterprise's business goals.Centrally located "enterprise geodatabases" can deliver immediate benefits to both the users and GIS data agencies: significantly reduced data development and management costs,controlled access to valid and current geo-spatial information,simplified data maintenance workflows, and more productive use of GIS throughout the enterprise.Database update services are one of Midwest Infotech's core competencies and go beyond just geo-database design & creation. Providing these services involves periodic enhancement and maintenance of the geo-databases, to ensure that these assets remain current and reflect physical changes in the real world as accurately as possible.

•      Specifically, the services include:
•           Geospatial enabling of legacy databases.
•           Enhancing existing geo-databases in terms of realigning geometric shapes to ensure positional accuracy,
                conflation, and retaining and/or updating of attribute information.
•           Allowing interoperability of geo-databases for different data formats
                and software platforms.

Midwest Infotech's geo-database experts have successfully guided our clients from isolated file-based GIS to highly available,highly scaleable,and extremely high performance geo-database implementations. We provide expertise in all major geo-database architectures,with specific emphasis on:

•           ESRI ArcSDE for Oracle and Microsoft SQL Server.
•           Oracle 9i, Oracle 10g Locator and Spatial Options.
