The Flood Map for Planning Flood Zones data is a very large national dataset. It can be challenging to import this data for a particular area but this guide will demonstrate how the data can be imported easily into PostGIS.

Step-by-step guide

1. If the data is to be loaded into PostGIS first ensure that a suitable schema exists in the database.

2. Copy the WFS URL from https://environment.data.gov.uk/dataset/04532375-a198-476e-985e-0579a0a11b47

3. Create a Workflow WFS Connection using the URL.

4. Identify the bounding box required. It should be in this format: minx miny maxx maxy.

5. Create a Spatial Data Transformation task.

   1. Select the WFS as the source and specify a destination schema and table name.

   2. Add the following to the additional parameters in Expert mode: “-spat <minx> <miny> <maxx> <maxy> --config OGR_WFS_PAGING_ALLOWED ON”.

   3. Set the geometry type to MULTIPOLYGON

      Open

      

6. Once loaded configure a layer in Studio for iShare GIS. Be aware that in this example the geometry was stored in a ‘shape’ field, not ‘wkb_geometry’. Under the advanced button in the Layer Configuration dialog it is possible to select a custom geometry field.
