The BAG Toolkit is used to model with the BAG. The current version of the toolkit works with the BAG 2.0 format.
The BAG is a rich dataset which can be used in many applications, but its exchange format (xml/gml) 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, derive entities/attributes and use the BAG addresses for geocoding.
The following extra attributes are or can be calculated:
- residential type (woningtype), see for example residential type layer in a residential services webmap application
- altitude
The snapshot process also generates an address table, with RD-coordinates.
The BAG Toolkit consists of three tools:
- BAG20 Xml2FSS -> To make the BAG available in a format suitable for modelling.
- BAG20 MakeSnapshot -> To make a snapshot of the BAG at a specific date.
- GeoCode -> To geocode addresses with meta information on how the results are derived. This tool we developed with the Spinlab department of the VU.
- The toolkits also contains a script called: BAG20_ReadAndProcessSnaphot.dms, as an example on how to read the results of a snapshot and process it for different applications. This configuration is documented here.
- In the /bat subfolder the RunMultipleMakeSnapshots.bat shows an example how to make a set of snapshots for different dates with a batch file.
- GeoDMS version 8.8.1 or later
- Internal ram: 16 GB or more (as the BAG is a large dataset)
- Hard disk space: 40 GB or more
- Access rights to your LocalDataDir (default: C:\LocalData) and SourceDataDir (default: C:\SourceData). If not adjust these placeholders with the GeoDMS GUI: menu option > Tools > Options > Advanced tab.
- For height information in snapshot, download the PHN and unzip it in your %SourceDataDir%/PHN folder. PHN stands for: Pand Hoogte Nederland, based on the AHN4.
The BAG Toolkit is available under GNU-GPL version 3 license.
The BAG Toolkit scrips can be downloaded here. Activate the green Code tool, use the url to make a GIT clone or just download the code as zip file and unzip this file in a project folder like: D:\prj\BAGTools.
- Since 2020, BAG snapshots in Geopackage format are also available via Geoparaat.
- This configuration example (with data) show how a BAG snapshot can be used to relate attributes (e.g. to calculate the vbo surface or the address range for each pand) or how to make grid maps with the BAG.
