GEODECI
Decisions you can justify, from the map.
What to do, where, in which order, and at what cost. The data behind the choice is delivered with it.
Guess where
Five stylised extracts. Drop a pin. The score is a geodesic distance.
No account. The score stays on this page.
Extract 1 of 5
Local tangent plane, north up. Not a Lambert-93 sheet: the scale is approximate.
Tap the map to move the pin, or place it at the center. Arrow keys pan when the map is selected. Then confirm.
No pin yet.
Sectors
The decision changes name. The method does not: written criteria, reliable data, a trail, a human choice.

In practice
Sectors
Local authorities, planning and land, water, energy and renewables, networks including telecom, environment, engineering firms and construction. We work in France, Belgium, Switzerland and Luxembourg.
A trail you can audit
The choice is traced, so it can be explained later.
Open tools
No dependency on a licence or a vendor.
What is public
What is public today: three open QGIS plugins on the official repository. They prepare compliant data, keep a change trail, and let you run the same process again.

What the public code already shows.
A change trail, conformant data, and one telecom example, read from public code.
Resources
Deciding with reliable geographic data.
One method, ten questions, a 90-day sequence. Then the network study.
Decision Diagnostic
A short fixed scope. We name what costs money or blocks the work, and the first action to take.
