Now, we have an understanding of what an application schema is, and we have our instance of GeoServer ready to serve data based on one. It is time to get our hands dirty with a simple example. For this example, we are going to continue with the idea (presented earlier) of delivering a road network dataset using the INSPIRE Annex I Road Transport Network schema. Specific details on what this schema is can be found in the INSPIRE data-specification document, D2.8.1.7, available at http://inspire.jrc.ec.europa.eu/documents/Data_Specifications/INSPIRE_DataSpecification_TN_v3.1.pdf.
We will use the following steps to create a simple implementation of the Road Transport Network schema using some free OpenStreetMap data:
We will first prepare our source dataset in a PostGIS database.
Then, we will configure the data store to hold our application schema dataset.
After that, we will create the application schema mapping file.
Finally, we will bring it all together...
