WebGIS
The WebGIS is a cartographic viewer for the consultation and visualization of GIS data via web. The word is in fact composed of Web (the internet network) and GIS, an acronym of Geographic information system. Compared to the simple GIS, it allows users to store, view, consult and manage online all spatial data (associated with geographic coordinates) through a map and the related non-spatial information through tables.
The WebGIS is part of a Spatial Data Infrastructure (SDI) developed over the years at the CNR-ISMAR based in Bologna, in the framework of various national and international research projects and for operational requests. The other components of the SDI are: a relational spatial database inspired by the data models proposed by the INSPIRE Directive; a metadata catalogue that makes the data present in the WebGIS searchable and possibly accessible/reusable; and a cloud storage for data flow management.
Advantages:
• centralized information management;
• accesibility to information layers available through the metadata catalogue;
• download of cartographic data, if required;
• immediate distribution via OGC services (WMS, WFS, WCS);
• widespread diffusion;
• interaction in real time and without the need of specific software;
• management of different types of users.
