Accessing the Trap.NZ map feeds with QGIS
Create a new Server Connection and enter the WFS URL in the format described here
The WFS server is set to return a maximum of 10k features per request. If you have more than this number of features you must enable paging and set a page size less than 10,000. We recommend 5000.
You can then add individual or groups of layers to the map.
You can add a CQL filter to a WFS connection to filter features from the WSF server. This can greatly reduce the amount of data retrieved (speeding up the transfer and improving performance).
For example - if you are only interested in this year’s records, you could add a CQL filter to build the query as a filter before loading the layer from the server.
1. Connect to the server as above to see the list of available layers.
2. Select the layer you want to query (e.g. default-project-trap-records) and click the Build query button
When you add the layer now, only the filtered records (features) will be loaded.
