What is the bentley geospatial server

What is the Bentley Geospatial Server?

  • Geospatial Server is an Enterprise GIS

  • Using a unique Federated Information Management approach.

  • The idea is simple:

    • Index rather than convert

    • Find rather than search

  • Allows managing, indexing, editing, and plotting of :

    • Structured information, fixed schema

      • Spatial Database, DGN/XFM, Shapefile, …

    • Unstructured information, no schema

      • Raw DGN, DWG, Word, PowerPoint, …


The geospatial federated system way

The Geospatial Federated System Way

  • Federated System allows dealing with a wider range of information help considering all aspects of a project

    • Each topological primitive is stored once in the database

  • Each topological primitive can be associated with one or more features. For example:

    • An edge may be associated with two adjacent county boundaries

    • An edge may be associated with a land parcel and a river

  • Shared Editing is easier

  • Analysis is done using topological algorithms, using persistent relationships
