Abstract
We describe the XYZ GeoServer, an autonomous server for geometric computation. The server supports the storage of temporary data, incremental operations and the definition of macro operations. The data model of the GeoServer is composed of a geometry independent and of a geometry specific data model. This distinction makes it possible to easily modify the geometric data model. The server is based on the XYZ GeoBench, a loosely coupled collection of carefully crafted software packages for geometric computation. The GeoServer is a first example of a server supporting as communication interface the COSIMA-standard (Cooperative Spatial Information Management). COSIMA defines a protocol allowing different services to be linked via a communication network.
