GeoGateway -- GeoGateway (GDB) User Reference

GeoGateway (also known as GDB) is a technology allowing programs to access data in many geomatics file formats, in a uniform manner, without having to translate them before use in applications. GeoGateway includes access to imagery, vectors, attributes, projections and other auxiliary information of interest to users of geomatics applications.

Each file format supported by GeoGateway is implemented within the GeoGateway library. All data types, and access approaches from the generic GeoGateway Data Model that make sense are implemented in a seamless manner.

However, not all file formats support all datatypes, or access approaches. In fact currently only PCIDSK (the format on which the GeoGateway Data Model was modelled) supports all possible data types. It is therefore important to recognize that different formats have limitations. The ``Supported File Formats'' topics describe each of the supported file formats, and their limitations.
