Let's imagine that we work for a utilities company that is contracted to build a piece of underground pipeline. The job is not only to do the actual construction work, the company also has to negotiate with the land owners and obtain their legal agreements for the construction work. The company GIS department has been tasked to prepare a list of parcels that will be affected by the pipeline itself and the construction work - after all, builders do need to be able to get to a place with their heavy equipment.
Our job is, therefore, to do the following:
- Buffer the pipeline geometry with a radius of 100 m.
- Extract the buffer geometry off the database.
- Query a WFS service to obtain parcels that intersect with the pipeline buffer.
- Load the parcels data to the PostGIS database.
- Prepare a report with the parcel data.
We have visited Poland and the UK in the previous examples. For this example, we will fly over to New Zealand and consume a web feature service provided for us by LINZ...
