ArcGIS

ArcGIS Pro connects to Topolab over the OGC API - Features standard today, no toolbox required. This page covers the working OGC connection (generally available), then the dedicated toolbox that is in preview.

Connect over the OGC API (available today)

Topolab serves every collection through OGC API - Features, which ArcGIS Pro reads as an OGC API server. You need a key with the GIS_ACCESS addon; see Authentication.

1. Add the OGC API - Features server

1. Open the Catalog pane.

2. Right-click Servers and choose New OGC API Server (under New Server in some versions).

3. Set the server URL to the OGC base:

   https://api.topolab.nl/v1/ogc
   

4. Under the connection's HTTP/custom header settings, add a header with name X-API-Key and value tlb_prod_.... ArcGIS sends this header on every request to the server, which is how Topolab authenticates the connection.

5. Finish to save the connection.

The landing page is anonymous, but listing collections requires the key, you can confirm the URL outside ArcGIS:

curl -H "X-API-Key: tlb_prod_..." \
  "https://api.topolab.nl/v1/ogc/collections"

2. Add a collection as a feature layer

Expand the new server connection in the Catalog pane. Each collection is a Topolab dataset, addressed by its table name such as transport_infrastructure_bushaltes. Right-click a collection and choose Add To Current Map, or drag it into the map, to consume it as a feature layer.

Geometry arrives in WGS84 (EPSG:4326). ArcGIS reprojects on the fly to the map's coordinate system; use Export Features if you need the data stored in a projected CRS such as RD New (EPSG:28992).

The collection list and its contents are described in Collections.

Dedicated ArcGIS toolbox (preview)

A dedicated Topolab geoprocessing toolbox for ArcGIS Pro is in preview. It will add sign-in, dataset search, and credit-aware download tools you can run directly in ModelBuilder and Python, removing the manual server setup above. Until it ships, use the OGC API - Features server connection, which is generally available and fully supported.
