Multi-scale mapping, spatial analysis, remote sensing: Geographic Information Systems are transforming how territories are diagnosed and planned.

Planning a territory means arbitrating between competing uses in space. GIS gives that arbitration an objective, shared and updatable basis.

From data to decision

A well-built GIS aggregates heterogeneous layers — land, hydrography, networks, hazards — to reveal relationships invisible on a paper map and to objectify choices.

Remote sensing changes the scale

Satellite imagery and RTK drone surveys offer fast, centimetric coverage. Urban sprawl, vegetation cover change or flood extent can be tracked with unprecedented precision.

Direct support to urban planning

From master plans to land-use plans, GIS speeds up diagnostics, makes enforceable documents more reliable and eases consultation through maps everyone can read.
