Recipe-driven spatial data downloader for Netherlands geo-data

---

What is GISKit?

GISKit is a Python tool for downloading Dutch spatial data using simple JSON "recipes". Define what data you need and where you need it - GISKit handles the downloads and combines everything into a single GeoPackage.

Perfect for:

• Creating project underlays for construction/infrastructure projects
• Downloading base maps for GIS analysis
• Collecting spatial context data for locations
• Automating repetitive spatial data downloads

Key Features

• Recipe-Driven: Define your data needs in simple JSON
• PDOK Integration: Access to 50+ Dutch government spatial datasets
• Smart Downloads: Automatic bbox calculation from addresses
• Single Output: Everything combined in one GeoPackage
• CRS Handling: Automatic coordinate transformation
• Export Options: GeoPackage, GeoJSON, CityJSON, optional IFC/GLB

Quick Start

Installation

From PyPI (recommended):

pip install pygiskit

# With IFC export support (Python 3.10-3.12 only)
pip install pygiskit[ifc]

From source:

git clone https://github.com/sanderboer/py-giskit.git
cd py-giskit
pip install -e .

Your First Recipe

Create dam_square.json:

{
  "name": "Dam Square Buildings",
  "location": {
    "type": "address",
    "value": "Dam 1, Amsterdam",
    "radius": 500
  },
  "datasets": [
    {
      "provider": "pdok",
      "service": "bgt",
      "layers": ["pand", "wegdeel"]
    }
  ],
  "output": {
    "path": "./dam_square.gpkg",
    "crs": "EPSG:28992"
  }
}

Run it:

giskit run dam_square.json

Result: dam_square.gpkg with buildings and roads around Dam Square!

Recipe Examples

All examples are in the recipes/ directory. Try them out:

# Download buildings and infrastructure around Curieweg, Spijkenisse
giskit run recipes/curieweg_multi_service.json

# Amsterdam Dam Square with buildings
giskit run recipes/amsterdam_dam_square.json

# Simple bbox example
giskit run recipes/bbox_simple.json

Available Data Sources

PDOK (Platform Digitale Overheid - Netherlands)

GISKit provides access to 50+ Dutch government datasets via PDOK's OGC API Features:

Base Registries (Basisregistraties):

• BGT - Large Scale Topography (54 layers: buildings, roads, water, terrain, etc.)
• BAG - Buildings and Addresses (buildings, addresses, residence objects)
• BAG3D - 3D Building Models (LoD 1.2, 1.3, 2.2 in CityJSON format)
• BRK - Cadastral Parcels

Infrastructure:

• NWB Roads - National Road Database (road segments, junctions)
• NWB Waterways - Waterway network

Statistics & Administration:

• CBS Neighborhoods 2024 - Statistical areas (neighborhoods, districts, municipalities)
• Administrative Boundaries - Municipalities, provinces, water boards

Environment:

• Protected Areas - Nature reserves, Natura 2000
• Soil Data - Soil types, contamination

See docs/PDOK_SERVICES.md for complete catalog with all layers.

Planned Providers

• OpenStreetMap - Global POI, buildings, roads via Overpass API
• AHN Elevation - Dutch elevation data via WCS
• Aerial Imagery - Luchtfoto via WMTS

CLI Commands

Run recipes:

# Execute a recipe
giskit run recipe.json

# Validate recipe syntax
giskit recipe validate recipe.json

Explore providers:

# List available providers and services
giskit providers list

# Show PDOK service details
giskit providers info pdok

# Search for specific data
giskit search "buildings"

Monitor API quirks:

# Show known API quirks for providers
giskit quirks list

# Show details for specific provider
giskit quirks show pdok ogc-features

# Monitor which quirks are being applied
giskit quirks monitor

Export Formats

Built-in formats:

• GeoPackage (.gpkg) - default, recommended
• GeoJSON (.geojson)
• Shapefile (.shp)
• CityJSON (.json) - for 3D data

Optional IFC/GLB export:

Requires pip install giskit[ifc] (Python 3.10-3.12 only)

# Export GeoPackage to IFC
giskit export ifc data.gpkg output.ifc

# Convert IFC to GLB (for web viewers)
giskit export glb data.ifc output.glb

See notes/EXPORT_GUIDE.md for details.

How It Works

1. Define - Write a JSON recipe with location and datasets
2. Geocode - GISKit converts addresses to coordinates
3. Download - Fetches data from PDOK OGC API Features
4. Transform - Converts to target CRS if needed
5. Combine - Merges all layers into single GeoPackage
