The BAG Toolkit is used to model with the BAG. The BAG is a rich dataset wich can be used in many applications, but it's exchange format (xml) is not very convenient for calculations and selections.
With the BAG Toolkit you can make the data available in a suitable format for modelling, calculate snapshots and derived entities/attributes and use the BAG adresses for geocoding.


The BAG Toolkit consists of three tools:

  • Xml2FSS -> To make the BAG available in a format suitable for modelling.
  • MakeSnapshot -> To make a snapshot of the BAG at a specific date and optional for a geographic extent and calculate derived entities and attributes.
  • GeoCode -> To geocode addresses in batch with relevant meta information on how the results are derived. This tool we developped with the Spinlab department of the VU.


  • GeoDMS version 7.130 or later, see Setup
  • Internal ram: 16 Gb or more (as the BAG is a very large dataset)
  • Hard disk space: 10 Gbyte or more
  • Access rights to your LocalDataDir (C:\LocalData) and SourceDataDir (default D:\SourceData). If not adjust these placeholders with the GeoDMS GUI > Tools > Options.

The Bag Toolkit scrips can be downloaded here. For the Vesta model download this version (it also includes calculating the number of floors of a BAG pand, based on the OHN data).
