G.I.S.

Ξεκινώντας είναι σκόπιμο να γνωρίζουμε περί τίνος μιλάμε.

Άρα η πρώτη ερώτηση είναι:
Τι είναι G.I.S.;

Μια απάντηση δίνεται στην Wikipedia στο σχετικό άρθρο: Geographic information System

Geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data. The acronym GIS is sometimes used for geographical information science or geospatial information studies to refer to the academic discipline or career of working with geographic information systems. In the simplest terms, GIS is the merging of cartography, statistical analysis, and database technology.

A GIS can be thought of as a system—it digitally creates and «manipulates» spatial areas that may be jurisdictional, purpose, or application-oriented. Generally, a GIS is custom-designed for an organization. Hence, a GIS developed for an application, jurisdiction, enterprise, or purpose may not be necessarily interoperable or compatible with a GIS that has been developed for some other application, jurisdiction, enterprise, or purpose. What goes beyond a GIS is a spatial data infrastructure, a concept that has no such restrictive boundaries.

In a general sense, the term describes any information system that integrates, stores, edits, analyzes, shares, and displays geographic information for informing decision making. GIS applications are tools that allow users to create interactive queries (user-created searches), analyze spatial information, edit data in maps, and present the results of all these operations. Geographic information science is the science underlying geographic concepts, applications, and systems.

Ο επόμενος ορισμός είναι πιο «ποιητικός» αλλά σίγουρα σε συνδυασμό με τον ανωτέρω, ξεκαθαρίζει ότι G.I.S. σημαίνει: Σύστημα Γεωγραφικών Πληροφοριών και όχι Γεωγραφικό Σύστημα Πληροφοριών ή Γεωγραφικό Πληροφοριακό Σύστημα.

…we see GIS as providing a gateway
to science and problem solving (geographic information
systems ‘and science’ in general), and because we relate
available software for handling geographic information
to the scientific principles that should govern its use
(geographic information: ‘systems and science’). GIS
is of enduring importance because of its central coordinating
principles, the specialist techniques that have
been developed to handle spatial data, the special analysis
methods that are key to spatial data, and because of the
particular management issues presented by geographic
information (GI) handling…

Είναι ξεκάθαρο ότι μιλάμε για διαχείριση γεωγραφικών πληροφοριών από ένα σύστημα. Άρα οι πληροφορίες είναι γεωγραφικές και όχι το σύστημα.
