To answer to such fundamental queries about the human
environment organisation it is necessary to access to:
- A set of relevant information about the study subject (study area).
- Methods and techniques for analysing this information with specific objectives:
-
- Exploration: What?
- Modelling: Why? How?
- Acting, forecasting and planning: And then?

Geographic Information Science (often called Geomatics or Geo-processing)
and its operational environment –the Geographic Information System (GIS-
offers methodological processes (made of methods, techniques and tools) to construct
and to exploit the geographic information. Spatial analysis (SA) is obviously concerned
with the exploitation stage. However, as seen and illustrated in the Basic Level of this
GITTA course, numerous interactions take place between the construction and the exploitation
process. Let us recall some major steps.
