Open Data

A consultation service allows “to perform at least the following operations: Visualization, navigation, variation of the display scale (zoom in and zoom Out), variation of the portion of territory framed (pan), overlap of the set of Searchable spatial data and visualization of the information contained in the legends and any relevant content of the metadata “(Directive 2007/2/EC).

The INSPIRE guidelines for the implementation of consultation services suggest that this service is implemented by using the standard ISO 19128 – Web Map Service (WMS) 1.3.0.

The WMS (Web map Service), generated according to the standard, delivers a map that is the representation of spatial information in the form of a digital image file in PNG, GIF or JPEG format: The map Therefore, as an image, cannot be edited or spatially Analyzed by end users.

However, the use of image formats that support the transparent background allows overlapping of different maps that can be requested by different servers.

A download or download service “allows you to download copies of spatial data sets or part of them and, where feasible, to access them directly” (Directive 2007/2/EC).INSPIRE Guidelines for the implementation of download services, for vector data, advise that this service, with direct access, is implemented using the standard ISO 19142 Web Feature Service supporting ISO 19143 Filter Encoding (OGC Web Feature Service 2.0 and OGC Filter Encoding 2.0)The standard-generated WFS (Web Feature Service) provides the end user with an XML based on the Geography Markup Language (GML) allowing the transfer of individual geospatial entities and therefore direct access to territorial information with the possibility to analyze and directly process the spatial data from different sources.
