A WFS - Web Feature Service is a standard Open Gis Consortium (OGC) service that allows a client to request, analyze and/or import geographic objects via the Web. This WFS has the "Real estates and anthropizations" layer of the Reference Territorial Database of Entities (BDTRE), structured according to the national technical specifications (DPCM November 10, 2011), collects the definition of all those objects that derive from anthropic activity in the territory and which do not constitute transport infrastructure (described instead in the specific stratum). The contents of this service are divided into the following levels corresponding to the BDTRE classes:- buildings (both of a residential and industrial nature and service sector activities);- artefacts (works that do not have a stable character in terms of habitability and human tracking); variously located in the territory; - works for transport (works such as artifacts but of greater complexity); - works for soil protection; - hydraulic works for defense and hydraulic regulation. We remind you that the data can be used for the uses permitted for one's own activity.
