Abstract

Harmonised INSPIRE data can be effectively used by GIS experts mostly using a GIS desktop environment. This scenario requires specific skills in using GIS softwares, which only a small portion of the potentially interested stakeholders have.

To overcome this problem and to facilitate the access and use of harmonised INSPIRE data also by non-GIS experts, it is recommended to develop one or more web applications, easily accessible via browser by desktop or laptop computers and/or via mobile devices (smartphones and/or tablets).

In the context of the ELISE Energy Pilot project, the sample data set of the Energy Performance Certificate provided by the Agency for the Water Resources and Energy of the Autonomous Province of Trento has been used to provide an example web application to allow common users to access the harmonised INSPIRE data. The Energy Pilot is using an extension of the INSPIRE Buildings data model to integrate the energy performance data.

This prototype provides access to the energy performance certificates data-sets in a direct visual way, easy understandable also by non GIS expert users. The application directly adds layer on top of the basemaps, showing the buildings that have an energy performance certificate. The layer is thematised with different colors based on the energy performance label of the building and a pop-up shows some of the attributes of the certficate. This web application can be considered as an example of INSPIRE Spatial Data Service implementation.

It has been implemented using the most common open source JavaScript libraries that supports complex GIS operations (OpenLayers and Leaflet). The input data-set comes from a WFS 2.0.0 service response encoded in INSPIRE GML 3.2 (produced using an INSPIRE extended schema). The WFS 2.0.0 and GML 3.2 are is difficult to be handled using available web map libraries. Most of the implementations based on those libraries use the GeoJSON as input format for the data set. In order to handle this format in an easy and performant way, an XSLT-based live transformation proxy has been implemented (capable also of handling CRS transformation).

The presentation will describe the current features of the prototype web app, the provided advantages as well as future development plans.
