Description:
!!! La Chasse aux Repères Français - The French Benchmarks Hunting !!!
Expanded Description:

Afin de localiser un objet sur la Terre il faut définir un Système Géodésique.
En France, il a donc été créé un Réseau Géodésique physiquement lié à la croute terrestre (borne, pilier, plaque, repère, etc…) dont les coordonnées et/ou l’altitude sont connues avec précision.
(Plus d'info sur la Géodésie)

La Nouvelle Triangulation Française (NTF) a été mise en place de la fin du XIXème siècle à 1991 et était matérialisée sur le terrain par:
 - 800 points de 1er Ordre espacés d’environ 30km,
 - 5 000 points de 2eme Ordre espacés d’environ 10km,
 - 60 000 points de 3eme et 4eme Ordre espacés d’environ 3km,
 - 20 000 points complémentaires de 5eme et 6eme Ordre (moins précis).
(Plus d'info sur la NTF)

Le Réseau Géodésique Français (RGF93) est le successeur de la Nouvelle Triangulation de la France (NTF) qu'il a officiellement remplacé en 2000.
C'est la réalisation nationale d'un système de référence tridimensionnel mondial, de précision centimétrique, adapté aux technologies modernes de positionnement.
Il est composé de:
 - 23 points du Réseau de Référence Français (RRF déterminés par Géodésie)
 - 1 009 sites du Réseau de Base de la France (RBF déterminé par GPS)
Les fiches détaillées sont accessibles sur le Site Géodésie et sur Geoportail RBF.
Il est complèté par environ 75 000 points du Réseau de Détail de la France (RDF).
Les fiches détaillées sont accessibles sur le Site Géodésie et sur Geoportail RDF.

Le Réseau GPS Permanent (RGP) est un ensemble organisé de stations de référence géodésiques implantées au sol de manière permanente, qui enregistrent ou émettent régulièrement leurs données d'observations.
Les fiches des stations sont accessibles sur le Site RGP et sur Geoportail RGP.

Le Réseau de Nivellement Général de la France (NGF):
Il a nécessité l'observation et le calcul de plus de 450 000 repères, généralement placés sur des ’’points durs’’ tels que ponts, soubassements de bâtiments, à environ un mètre du sol.
Tous ont (ou ont eu) une plaque indiquant l'altitude du lieu. Leur forme permet de s'en servir comme appui pour y poser une mire de Géomètre.
Les fiches détaillées sont accessibles sur le Site Géodésie et sur Geoportail NGF.

L’évolution des réseaux géodésiques vers des réseaux actifs utilisant les systèmes de positionnement satellitaires est le fait le plus marquant de ces dernières années.
Toutes les fiches ne sont donc plus maintenues dans les bases de données de l'IGN.

D'autres types de repères physiques méritent également d'être mémorisés afin de ne pas les oublier et d'en permettre la visite.

[EN] To locate an object on Earth it is necessary to define a Geodesic System of reference.
In France, a Geodesic grid has been created which is physically linked to the Earth's crust (marker, piller, plaque, benchmark, etc.) and for which the coordinates and/or altitude are precisely identified.

The New French Triangulation (NTF) consists of :
 - 800 points of 1st Order spaced about 30km apart,
 - 5 000 points of 2nd Order spaced about 10km apart,
 - 60 000 points of 3rd and 4th Order spaced about 3km apart,
 - 20 000 supplementary points of 5th and 6th Order (less accurate).

The French Geodesic Grid (RGF) is the successor to the New French Triangulation (NTF).
It is the national implementation of a worldwide three-dimensional system of reference, precise to the centimeter, and adapted to modern positioning technologies.
It is composed of:
 - 23 points of the French reference grid (RRF determined by Geodesics)
 - 1 009 sites of the French Base Grid (RBF determined by GPS)

The French general geodesic leveling grid (NGF):
This grid required the observation and calculation of more than 450 000 benchmarks, generally placed on "durable points" such as bridges, the base of buildings, at about one meter above the ground level. All have (or had) a plaque indicating  the altitude of the location.
Their form allows them to be used as a support for a survey leveling instrument.

All of these points are classified by the National Geographical Institute (IGN) and are individually catalogued.

You will easily find the entries for these points at geodesie.ign.fr  or geoportail.fr

Instructions for Posting a French Benchmarks Waymark:
Pour créer un Waymark dans cette catégorie, vous devez:
- Ajouter une photo en gros plan du point à trouver (une photo à plusieurs mètres du point est aussi souhaitable),
- Joindre l'adresse Internet de la fiche IGN.
Si la fiche IGN n'existe plus (Point IGN = Non), votre description devra être très précise.

To create a Waymark in this category, you must:
- Upload a photograph with the point to be found clearly depicting in the foreground,
- Indicate the Internet address of the IGN entry.
Instructions for Visiting a Waymark in this Category:
La condition pour loguer ce Waymark, à moins que son créateur ait défini une autre demande, sera au minimum une photo de Vous et/ou de votre GPS à ce point géodésique.
The requirement for logging this Waymark, unless if its creator defined another request, will be at least a picture of You and/or your GPS at this geodetic point.
