Key Features and Functionalities

3D City Database

  • Spatial relational database schema for semantic 3D city models
  • All thematic modules from CityGML 2.0 included
  • Five different Levels of Detail (LODs)
  • Appearance data (e.g. textures, colors) in addition
    to flexible 3D geometries
  • Supports generic and prototypical 3D objects
  • Complex digital terrain models (DTMs)
  • Web Feature Service (WFS) interface
  • Works with Oracle Spatial 10g, 11g, and 12c (Spatial and Locator), or PostGIS 2.0 or higher
  • Docker containers available for quick setup

3D City Database Importer/Exporter

  • Full support for importing/exporting of CityGML 2.0 and 1.0 datasets; support for tiled import/export
  • Export of KML/COLLADA/glTF models to be used with GIS and Digital Globe Browsers like ArcGIS, CesiumJS, Google Earth, or iTowns
  • Generic KML information balloons
  • Reading/writing CityGML documents of arbitrary file size; gzip & zip compression supported
  • Powerful query & filter capabilities
  • Multithreaded programming facilitating high-performance processing
  • Resolving of forward and backwards XLinks
  • XML validation of CityGML documents
  • User-defined Coordinate Reference Systems
  • Coordinate transformations for CityGML exports
  • Export of thematic data to spreadsheets (CSV and Microsoft Excel)
  • Batch mode & Graphical User Interface

3DCityDB-Web-Map-Client

  • Extension of the CesiumJS 3D virtual globe by:
  • Support for efficient displaying, dynamic loading and unloading of large 3D visualization models in the form of tiled KML/glTF datasets exported from the 3DCityDB using the Importer/Exporter
  • Layer management for adding and removing an arbitrary number of data layers like 3D visualization model (KML/glTF), 3DTiles datasets, WMS imagery layer, and Cesium digital terrain model
  • 3D visualization models can be linked with Google Fusion Tables for dynamic querying of thematic data for every 3D object
  • Rich interaction with 3D visualization models, e.g. highlighting of 3D objects on mouse-over and mouse click as well as hiding of selected 3D objects
  • Toggle shadow casting for 3D objects and terrain
  • Explore a selected 3D object from different view perspectives using third-party services like Microsoft Bing Maps oblique view, Google Streetview, and a combined version (DualMaps)
  • Save and share 3DCityDB web client projects using scene links (everything is stored in the URL)
